Super Precision Angular Contact Ball Bearings S7213 ACDGA/HCP4A

Super Precision Angular Contact Ball Bearings S7213 ACDGA/HCP4A

The S7213 ACDGA/HCP4A is a super precision angular contact ball bearing with a 65mm bore and 120mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 14332 lbf and operates smoothly at speeds up to 36,000 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 high-speed applications like machine tool spindles or precision equipment. It comes with an extra light preload (Class A) for reduced vibration and enhanced accuracy.

Weighing 0.88kg, it’s designed for universal matching in back-to-back, face-to-face, or tandem arrangements. Compliant with P4A tolerance standards for reliable performance in temperatures from -30°C to 110°C.
