Stud Type Track Rollers of the series KRV-PP

Special feature of this series
Stud type track rollers of the series KRV-PP, with axial guidance, have no cage. They are based on a needle roller bearing and, because of the full complement needle roller set design, are suitable for higher radial and also axial load capacities than cage-guided stud type track rollers of the series KR and KRE. The surface of the outer ring is spherical, so they can compensate for misalignment. They have a three-stage seal consisting of axial plain washers made of rubber.
