Super-precision, high-speed B design, universally matchable single row angular contact ball bearing suitable for direct oil-air

These super-precision, high-speed, single row angular contact ball bearings with 15? or 25? contact angle accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. Compared to the equivalent SKF E design high-speed bearings, these are suited for lighter loads. Being universally matchable, they can be used together in arrangements to provide effective load sharing, within a predetermined preload range, without the use of shims or similar devices. They have two lubrication holes, an annular groove, and two annular O-ring grooves in their outer rings.

• Suitable for direct oil-air lubrication
• Very high running accuracy
• Accommodate high speeds
• Reduced stresses on rolling contact surfaces
• Universally matchable
