Family specifications and selection conditions
| Product description | Spherical roller bearings can accommodate heavy loads in both directions. They are self-aligning and accommodate misalignment and shaft deflections, with virtually no increase in friction or temperature. Under normal operating conditions, sealed bearings are almost maintenance-free, keeping service costs and grease consumption low. The design includes features to facilitate relubrication. Also available on request with special sized bore and/or outside diameters, suitable for reworked shafts and housings. |
|---|---|
| Manufacturer features | Accommodate misalignment up to 0.5 degree • High load carrying capacity • Sealed for increased reliability, with relubrication features • Low friction and long service life • Increased wear resistance |
