Super Precision Angular Contact Ball Bearings S71915 ACDGA/HCP4A

Super Precision Angular Contact Ball Bearings S71915 ACDGA/HCP4A

The S71915 ACDGA/HCP4A is a super precision angular contact ball bearing with a 75mm bore and 105mm outer diameter, crafted from chrome steel for durability. Its 25° contact angle and ceramic balls ensure smooth operation under radial loads up to 7605 lbf.

Sealed for protection, this bearing runs at high speeds up to 28,000 RPM and handles temperatures from -30°C to 110°C. The phenolic cage adds strength while keeping it lightweight at just 0.3kg.

With an extra light preload (Class A), it’s ideal for precision applications like machine tool spindles or high-speed robotics. The P4A tolerance class guarantees consistent performance.

This model is interchangeable with SKF bearings and comes in sets of three for universal matching (back-to-back, face-to-face, or tandem). Its grease lubrication makes maintenance straightforward.
