Spherical roller bearing for continuous casters, with relubrication featuresSpherical 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. This variant is optimized for use in continuous casters in the metals industry. The design includes features to facilitate relubrication. The bearings are developed for very slow rotation speed.
- Accommodate misalignment
- High load carrying capacity
- Low friction and long service life
- Increased wear resistance
- Suitable only for very low speed
