Family specifications and selection conditions
| Product description | Single row tapered roller bearings are designed to accommodate combined radial and axial loads and provide low friction during operation. The inner ring, with rollers and cage, can be mounted separately from the outer ring. These separable and interchangeable components facilitate mounting, dismounting and maintenance. By mounting one single row tapered roller bearing against another and applying a preload, a rigid bearing application can be achieved. Also available on request with special sized bore and/or outside diameters, suitable for reworked shafts and housings. |
|---|---|
| Manufacturer features | High radial and axial load carrying capacity • Accommodate axial loads in one direction • Low friction and long service life • Separable and interchangeable components |
