Product Details

Feature

1. Low friction (roller end face / flange contact zone)

The open flange design, in conjunction with the roller end design and surface finish, promotes the formation of a lubricant film with low friction and high axial basic load ratings.

2. Long service life

The roller logarithmic curve profile reduces edge stress at the roller/race contact and sensitivity to misalignment and shaft deflection.

3. Improve operational reliability

The surface finish of the roller and raceway contact surfaces facilitates the formation of a hydrodynamic lubricating oil film.

4. Separable and interchangeable

The separate components are interchangeable. This facilitates installation, disassembly, and maintenance inspection.

5. High speed capability

The cage is designed for high speeds, high accelerations and shock loads.
