High-Speed NSK Angular Contact Ball Bearings 71930C to 71936P

High-Speed NSK Angular Contact Ball Bearings 71930C to 71936P

NSK high-speed angular contact ball bearings, ranging from 71930C to 71936P, are engineered to meet the demands of industrial machinery. These bearings feature a robust design capable of handling high axial loads, especially in high-speed environments. With options for various contact angles, they are versatile and suited for a wide range of applications.

Features and Specifications:

• Contact Angle Options: Available in contact angles of 15° (C), 30° (A), 40° (B), and special production angles of 25° (A5). A larger contact angle offers a greater capacity for axial load-bearing.
• Material and Construction: Manufactured with high-quality steel balls and retainers made of steel, brass, or engineering plastic. Retainer formation varies between pressing and turning, depending on the bearing design and usage conditions.
• Load Capacity: Primarily designed to handle significant one-way axial loads. The higher the contact angle, the better the ability to support heavy loads.
