Features
- it consists of a machined massive outer ring with rib, a needle roller and cage assembly and a separable inner ring
- suitable for high radial load capacities
- wider than needle roller bearings of the series 49 and therefore suitable for significantly higher radial loads
- seal: open (without seal); for higher speeds than with sealed ball bearings and easy relubrication
- can be used if the surface of the shaft is not suitable as a raceway
