product features
The cylindrical roller is in line contact with the raceway and has a large radial load capacity. Suitable for both heavy and shock loads, as well as for high speed rotation.
Cylindrical roller bearing raceways and rolling elements are geometric. After the improved design, the new load-bearing capacity, the new structural design of the rib and the roller end face not only improve the axial bearing capacity of the bearing, but also improve the lubrication conditions of the contact area between the roller end face and the rib, and improve the lubrication condition.
