Low friction (roller end face/edge contact area)
The open edge design, as well as the roller end design and surface finish, promote the lubricating oil film, thereby reducing friction and bringing higher basic rated load.
long service life
The logarithmic curve profile of the roller reduces the edge stress at the contact between the roller and the raceway, as well as the sensitivity to misalignment and axial deflection.
Improve operational reliability
The surface treatment of the contact surface between the roller and the raceway is beneficial for the formation of a hydrodynamic lubricating oil film.
Separable and interchangeable
The separation components of cylindrical roller bearings are interchangeable. This facilitates installation, disassembly, maintenance, and inspection.
High speed capability
The cage design is suitable for high speed, rapid acceleration, and maximum load.
