What is the 70 Series?

Engineered for ultimate velocity, the Welink Bearing 70 Series Angular Contact Ball Bearing features a slim cross-section designed to handle combined radial and unidirectional axial loads simultaneously. It is specifically optimized for ultra-high-speed operations.

Key Advantages & Features

• High-Speed Optimization: Internal geometry and contact angles (e.g., 15°, 25°) are tailored for maximum RPM.

• Low Heat Generation: Slim profile and precision P4/P5 grades minimize friction and thermal expansion.

• High Rigidity: Excellent rotational accuracy when mounted in duplex or multiplex pairs.

Application Areas

The primary choice for high-speed machine tool spindles, precision grinding machines, and high-frequency motors.

Solutions Provided

For precision machining applications where standard bearings overheat or lose accuracy at extremely high speeds, the 70 Series provides a cool-running, highly rigid spindle solution that guarantees microscopic machining tolerances.
