Timken Thrust Tapered Roller Bearings Guide
Product Description
The TIMKEN 81577DW / 81962 thrust tapered roller bearing features a two-row design consisting of one double inner ring with a keyway, two single outer rings, and two rows of tapered rollers. The steep contact angles provide high axial load capacity in both directions, while the keyway helps prevent inner ring rotation and bore fretting. Its robust construction ensures stable axial support and reliable performance under heavy rolling loads.
The bearing 81577DW / 81962 is typically used in axial positions for work rolls subjected to high axial loads and in backup roll thrust positions. Its high axial load capacity and rigid construction help maintain stable roll positioning and provide reliable axial support under continuous heavy loads and demanding operating conditions, ensuring stable rolling mill operation.
