NSK Angular Contact Ball Bearings 7000 – High-Speed Machine Tool Bearings

NSK Angular Contact Ball Bearings 7000 – High-Speed Machine Tool Bearings

The NSK 7000 Angular Contact Ball Bearings are designed for high-speed precision applications, particularly in machine tools. With their specialized contact angles (15°, 30°, 40°, and special 25° versions), these bearings can handle significant one-way axial loads, with a greater contact angle offering a higher load capacity. Constructed with high-quality steel balls and available in multiple configurations, they ensure efficient and reliable performance in demanding industrial environments.
