Spherical roller bearing with tapered boreSpherical 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. They can be used in a modular system, including housings, sleeves and nuts.
- Accommodate misalignment
- High load carrying capacity
- Low friction and long service life
- Increased wear resistance
