That combined-load job is exactly why selecting one is harder than picking a standard bearing.<\/p>\n      <\/div>\n    <\/div>\n\n    <div class=\"aub-slew-main-grid\">\n      \n      <div class=\"aub-slew-content-col\">\n        <div class=\"aub-slew-sys-label\">[SYS-01] COMPONENT DEFINITION<\/div>\n        <h3 class=\"aub-slew-h3\">What is a slewing bearing?<\/h3>\n        <p class=\"aub-slew-body\">A slewing bearing is a large-diameter rolling-element bearing \u2014 balls or rollers between two concentric rings \u2014 built to support axial, radial, and overturning (moment) loads simultaneously, usually below 10 RPM (load directions per ISO 76). Many include integral external or internal gear teeth so a pinion or slew drive can rotate them.<\/p>\n\n        <div class=\"aub-slew-sys-label\">[SYS-02] INDUSTRY GAP<\/div>\n        <p class=\"aub-slew-body\">Most OEM product pages list the bearing types and stop there. The dimensions, load ratings, materials, and hardened-depth data, the numbers an engineer actually need to size a bearing, sit behind a login, a selector tool, or a PDF request.<\/p>\n\n        <div class=\"aub-slew-alert-block\">\n          <p class=\"aub-slew-body aub-slew-p-strong\">That gap is expensive. Choosing on the wrong number risks a ring that passes an axial check yet fails years early under moment load, and because the deciding data is hidden the mistake only surfaces after install.<\/p>\n        <\/div>\n      <\/div>\n\n      <div class=\"aub-slew-media-col\">\n        <div class=\"aub-slew-media-frame\">\n          <div class=\"aub-slew-corner top-left\"><\/div>\n          <div class=\"aub-slew-corner bottom-right\"><\/div>\n          <img decoding=\"async\" class=\"aub-slew-img\" \n               src=\"https:\/\/aubrikmc.com\/wp-content\/uploads\/2026\/06\/What-is-a-slewing-bearing.png\" \n               alt=\"Slewing bearing carrying axial, radial, and tilting-moment loads\" \n               width=\"800\" height=\"600\" loading=\"lazy\">\n          \n          <div class=\"aub-slew-hud-badges\">\n            <div class=\"aub-slew-badge\">\n              <span class=\"aub-slew-badge-key\">LOAD REF<\/span>\n              <span class=\"aub-slew-badge-val\">ISO 76<\/span>\n            <\/div>\n            <div class=\"aub-slew-badge\">\n              <span class=\"aub-slew-badge-key\">MAX SPEED<\/span>\n              <span class=\"aub-slew-badge-val\">&lt; 10 RPM<\/span>\n            <\/div>\n            <div class=\"aub-slew-badge\">\n              <span class=\"aub-slew-badge-key\">SE-SERIES<\/span>\n              <span class=\"aub-slew-badge-val\">203 kN\u00b7m<\/span>\n            <\/div>\n          <\/div>\n        <\/div>\n      <\/div>\n\n    <\/div>\n\n    <div class=\"aub-slew-bottom-card\">\n      <div class=\"aub-slew-card-content\">\n        <div class=\"aub-slew-sys-label aub-slew-card-label\">[SYS-03] AUBRIK STANDARD<\/div>\n        <p class=\"aub-slew-card-body\">Aubrik publishes the numbers on the page instead.

Three-Row Roller<\/h2>\n      <\/div>\n      <div class=\"ud-slw-intro\">\n        <p>Engineers default to the highest-capacity type when a load look demanding. That instinct quietly wastes money: a three-row roller is frequently over-specified for a load a four-point ball would carry at a fraction of the cost and friction.<\/p>\n        <p>The honest trade-off is that the three constructions trade capacity, rigidity, friction, and price differently, so the \u201cbest\u201d type depends on your governing load, not on raw rating. A cross roller slewing bearing, for instance, wins on rigidity but costs more and runs with more friction than a ball type. Here&#8217;s the Construction-to-Load Decision Tree Aubrik uses, with the load and rigidity behavior verified against published engineering data and slewing-bearing patents.<\/p>\n      <\/div>\n    <\/div>\n\n    <h3 class=\"ud-slw-h3\">Construction-to-Load Decision Tree<\/h3>\n\n    <div class=\"ud-slw-panel-stack\">\n      \n      <div class=\"ud-slw-panel\">\n        <div class=\"ud-slw-watermark\">01<\/div>\n        <div class=\"ud-slw-viewport\">\n          <div class=\"ud-slw-crosshair ud-slw-crosshair-tl\"><\/div>\n          <div class=\"ud-slw-crosshair ud-slw-crosshair-tr\"><\/div>\n          <div class=\"ud-slw-crosshair ud-slw-crosshair-bl\"><\/div>\n          <div class=\"ud-slw-crosshair ud-slw-crosshair-br\"><\/div>\n          <div class=\"ud-slw-carousel\">\n            <div class=\"ud-slw-track\">\n              <img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/aubrikmc.com\/wp-content\/uploads\/2026\/06\/011-012.png\" alt=\"Single-row four-point contact ball 011-012 schematic\" width=\"400\" height=\"266\" \/>\n            <\/div>\n          <\/div>\n        <\/div>\n        <div class=\"ud-slw-data-grid\">\n          <div class=\"ud-slw-meta\">\n            <span class=\"ud-slw-index\">[SYS-01]<\/span>\n            <span class=\"ud-slw-series\">AUBRIK 010\u2013014<\/span>\n          <\/div>\n          <h4 class=\"ud-slw-h4\">Single-row four-point contact ball<\/h4>\n          <div class=\"ud-slw-specs\">\n            <div class=\"ud-slw-spec-item\"><span class=\"ud-slw-label\">Moment \/ Capacity<\/span><span class=\"ud-slw-val\">Medium<\/span><\/div>\n            <div class=\"ud-slw-spec-item\"><span class=\"ud-slw-label\">Rigidity<\/span><span class=\"ud-slw-val\">Medium<\/span><\/div>\n            <div class=\"ud-slw-spec-item\"><span class=\"ud-slw-label\">Friction<\/span><span class=\"ud-slw-val ud-slw-highlight\">Lowest<\/span><\/div>\n          <\/div>\n          <div class=\"ud-slw-scenario\">\n            <span class=\"ud-slw-scenario-title\">Application Scenario<\/span>\n            <span class=\"ud-slw-scenario-text\">Variable multi-directional load, weight-limited, efficiency matters<\/span>\n          <\/div>\n        <\/div>\n      <\/div>\n\n      <div class=\"ud-slw-panel\">\n        <div class=\"ud-slw-watermark\">02<\/div>\n        <div class=\"ud-slw-viewport\">\n          <div class=\"ud-slw-crosshair ud-slw-crosshair-tl\"><\/div>\n          <div class=\"ud-slw-crosshair ud-slw-crosshair-tr\"><\/div>\n          <div class=\"ud-slw-crosshair ud-slw-crosshair-bl\"><\/div>\n          <div class=\"ud-slw-crosshair ud-slw-crosshair-br\"><\/div>\n          <div class=\"ud-slw-carousel\">\n            <button class=\"ud-slw-nav ud-slw-prev\" aria-label=\"Previous image\"><svg viewBox=\"0 0 24 24\"><path d=\"M15.41 16.59L10.83 12l4.58-4.59L14 6l-6 6 6 6z\"\/><\/svg><\/button>\n            <button class=\"ud-slw-nav ud-slw-next\" aria-label=\"Next image\"><svg viewBox=\"0 0 24 24\"><path d=\"M8.59 16.59L13.17 12 8.59 7.41 10 6l6 6-6 6z\"\/><\/svg><\/button>\n            <div class=\"ud-slw-track\">\n              <img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/aubrikmc.com\/wp-content\/uploads\/2026\/06\/110.png\" alt=\"Single-row cross roller 110 schematic\" width=\"400\" height=\"266\" \/>\n              <img decoding=\"async\" src=\"https:\/\/aubrikmc.com\/wp-content\/uploads\/2026\/06\/111-112.png\" alt=\"Single-row cross roller 111-112 technical layout\" width=\"400\" height=\"266\" loading=\"lazy\" \/>\n            <\/div>\n            <div class=\"ud-slw-dots\">\n              <button class=\"ud-slw-dot ud-slw-active\" aria-label=\"Go to slide 1\"><\/button>\n              <button class=\"ud-slw-dot\" aria-label=\"Go to slide 2\"><\/button>\n            <\/div>\n          <\/div>\n        <\/div>\n        <div class=\"ud-slw-data-grid\">\n          <div class=\"ud-slw-meta\">\n            <span class=\"ud-slw-index\">[SYS-02]<\/span>\n            <span class=\"ud-slw-series\">AUBRIK 110\u2013112<\/span>\n          <\/div>\n          <h4 class=\"ud-slw-h4\">Single-row cross roller<\/h4>\n          <div class=\"ud-slw-specs\">\n            <div class=\"ud-slw-spec-item\"><span class=\"ud-slw-label\">Moment \/ Capacity<\/span><span class=\"ud-slw-val\">High<\/span><\/div>\n            <div class=\"ud-slw-spec-item\"><span class=\"ud-slw-label\">Rigidity<\/span><span class=\"ud-slw-val ud-slw-highlight\">Very High<\/span><\/div>\n            <div class=\"ud-slw-spec-item\"><span class=\"ud-slw-label\">Friction<\/span><span class=\"ud-slw-val\">Medium<\/span><\/div>\n          <\/div>\n          <div class=\"ud-slw-scenario\">\n            <span class=\"ud-slw-scenario-title\">Application Scenario<\/span>\n            <span class=\"ud-slw-scenario-text\">High moment + precision;

A slew drive integrates the slewing ring with a self-locking worm gear and a hydraulic or electric motor mount, so you get controlled rotation, holding torque, and an IP65-sealed package in one ready-to-install unit.<\/p>\n        <p class=\"abk-tech-desc-text\">That integration is where Aubrik separates from bearing-only suppliers: the SE series ships the bearing, worm gearbox, and seal as a tested assembly. The self-locking worm set holds the load without a brake, which is why these drives suit solar trackers, small wind turbines, and crane swing axes (slew-drive patents).

In real installations, cranes, excavators, wind turbines, robot bases, the tilting moment, not the thrust rating, is the binding constraint.\n                <\/div>\n                <div class=\"amc-dash-body\">\n                    Here is why it bites so hard. Under a tilting moment the load is not shared evenly; the most-loaded rolling element carries 3\u20135\u00d7 the average. And because bearing fatigue follows the inverse-cube life law of ISO 281, a peak element load just 1.5\u00d7 the average drops that element\u2019s life to roughly (1\/1.5)\u00b3 \u2248 30% of the even-distribution value.

Over-speccing to three-row when a ball passes adds cost, friction, and weight, not safety.\"}},{\"@type\":\"Question\",\"name\":\"Which sizes can Aubrik manufacture?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Bore\/OD from 200 mm to 6,000 mm, in four-point ball, cross-roller, and three-row roller, plus custom designs.\"}},{\"@type\":\"Question\",\"name\":\"What materials are slewing bearings made from?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Rings are 42CrMo (4140) \/ 40Cr \/ 50Mn alloy steel, normalized and tempered; raceways are induction-hardened to HRC 55\u201362 with controlled case depth, and corrosion or zinc-plated options are available on request.\"}},{\"@type\":\"Question\",\"name\":\"Why do slewing bearings fail, and how long do they last?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Most early failures trace to one of three root causes: sizing on axial load instead of tilting moment, mounting-flatness errors beyond 0.05\u20130.15 mm\/m, or lapsed relubrication that lets metal contact the raceway. Get those right and a well-maintained crane bearing reaches 10\u201315 years, with wind-turbine rings designed to 20.\"}},{\"@type\":\"Question\",\"name\":\"How can you tell a slew ring is worn?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Watch for resistance to swing or the boom over-travelling its stop, grinding during rotation, metal in extracted grease, and rising drive-motor current. Vibration monitoring flags raceway fatigue 2\u20136 months before it shows.\"}},{\"@type\":\"Question\",\"name\":\"Can a slewing bearing rotate continuously, and what lubrication does it need?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Most run intermittently below 10 RPM, but continuous rotation is fine within the rated speed. Use GB7324 No.2 lithium grease through the nipples; relube every 50 operating hours in harsh duty to 500+ hours in clean, lightly loaded service, and never mix incompatible grease thickeners.\"}},{\"@type\":\"Question\",\"name\":\"Are turntable bearings and slewing bearings the same?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"For industrial use, yes, one combined-load ring under two names. Aubrik builds the full range, from lighter rotary-table sizes to multi-metre crane rings.\"}},{\"@type\":\"Question\",\"name\":\"Do you offer custom \/ OEM slewing bearings and what is the lead time?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes, custom bore, load class, gearing, and mounting are standard, with OEM service and a one-year warranty. Send your drawing or load case for a part-number match, drawing, and quoted lead time from our two production bases.\"}}]}<\/script>\n<\/div><\/div><\/div>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Slewing Bearing Slewing Bearings &#038; Slewing Drives: Specs, Types &#038; Selection Open dimension tables, real load ratings, and a moment-first selection method, from a slewing bearing manufacturer that publishes what the catalogs hide.
