Timken Thrust Tapered Roller Bearings Guide
Product Description
The TIMKEN 378DW / 374 Thrust Tapered Roller Bearing features a two-row design consisting of one double inner ring with extended ribs and a keyway, two outer rings, and two rows of tapered rollers. The steep contact angles provide high axial load capacity in both directions, while the extended ribs and keyway contribute to stable roller guidance and secure inner ring positioning. Its robust construction provides rigid axial support and reliable performance under heavy rolling loads.
The bearing 378DW / 374 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.
