Roller bearings
Double-Row Tapered Roller Bearings
Two opposed rows in a single assembly give bidirectional axial capacity without a second bearing position — the arrangement used for pinion mounts and gear stands.
- Series
- Per drawing
- Bore
- 40 – 600 mm
- Class
- P5
Design
Both directions, one position.
Every batch is measured on the finished part, and the measurement file travels with the goods. Send a designation, a drawing or a photo of the failed part and an engineer will answer with a lead time and a price, usually inside 48 hours.
- Back-to-back or face-to-faceBack-to-back for stiffness at the pinion nose, face-to-face where misalignment has to be absorbed.
- Pre-set on assemblyClearance or preload is set and measured before the assembly leaves the bench.
- One outer ringA single outer ring keeps both rows in line through the housing fit.
- RebuildableCones, cups and cage supplied separately for overhaul programmes.

Where it is used
Common applicationsPinion mounts
Locating the pinion shaft in a gear stand in both directions.
Gear stands
Rolling-mill drive spindles where axial float must be eliminated.
Wheel hubs
Commercial-vehicle hubs with combined radial and axial load.
Reducer shafts
Worm and bevel reducers where a single bearing position must locate the shaft.
Send the part number.
We will send the answer.
A designation, a drawing, or a photo of the failed part is enough to start. Technical questions reach an engineer, not a mailbox.
