Super Precision Angular Contact Ball Bearings 71915 CD/P4ADBC

Super Precision Angular Contact Ball Bearings 71915 CD/P4ADBC

The 71915 CD/P4ADBC is a super precision angular contact ball bearing with a 75mm bore and 105mm outer diameter, crafted from high-quality chrome steel. It features a 15° contact angle and comes in a matched pair (DB arrangement) for balanced performance.

This bearing handles radial loads up to 13162 lbf and operates smoothly at speeds up to 36000 RPM. Its moderate preload (Class C) ensures stability, while the open design allows for easy lubrication.

The phenolic cage reduces friction and wear, making it durable for high-speed applications. With a temperature range of -30°C to 110°C, it’s suitable for demanding environments.

Ideal for precision machinery like spindles or CNC equipment, this bearing is interchangeable with SKF models. Weighing 0.7kg, it offers a robust yet lightweight solution for angular contact needs.

Compliant with P4A tolerance standards, it ensures reliable performance in critical applications. The 26 balls (9.525mm each) provide smooth rotation and even load distribution.
