Application of High Speed Bearing 719/8 CE/HCP4A

These super-precision, high-capacity, single row angular contact ball bearings accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. They are designed to accommodate heavy loads at relatively high speeds under low to moderate operating temperatures. 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.

• Very high running accuracy

• Very high load carrying capacity

• Relatively high speed and stiffness

• Universally matchable

719/8 Bearings we also can supply HQW Bearings, GRW Bearings, and TKW Brand bearings also finished testing by the customers, 

Advantages of 719/8 Bearings for turbo jet engine
