Super Precision Angular Contact Ball Bearings S71914 ACDGA/P4A

Super Precision Angular Contact Ball Bearings S71914 ACDGA/P4A

The S71914 ACDGA/P4A is a super precision angular contact ball bearing with a 70mm bore and 100mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 7312 lbf and operates smoothly at high speeds up to 28,000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet, long-lasting performance. The 25° contact angle provides excellent stability for angular loads.

This bearing is ideal for precision applications like machine tool spindles or high-speed motors. It comes with an extra light preload (Class A) for minimal friction.

Weighing just 0.34kg, it’s lightweight yet robust. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacements. Suitable for temperatures from -30°C to 110°C.
