RSTO 12
Support roller (yoke-type track roller), without flange rings and inner ringSupport rollers (yoke-type track rollers) are designed to run on all types of tracks and to be used in cam drives, conveyor systems, etc. They are based on a single row needle roller bearing without an inner ring, intended for applications where hardened and ground raceways can be provided on the pin or shaft. They have a thick-walled outer ring with a crowned running surface and are supplied ready-to-mount. The outer ring and the needle roller and cage assembly can be mounted separately.
- High radial load carrying capacity
- Able to withstand shock loads
- Long service life
- Ready to mount
- Separable design
