Super Precision Angular Contact Ball Bearings S7011 ACDGA/HCP4A

Super Precision Angular Contact Ball Bearings S7011 ACDGA/HCP4A

The S7011 ACDGA/HCP4A is a super precision angular contact ball bearing, measuring 55mm by 90mm by 18mm. Made from chrome steel with ceramic balls, it offers smooth operation and durability.

With a 25° contact angle, it handles both radial and axial loads efficiently. Its extra light preload ensures minimal friction, making it suitable for high-speed applications up to 34,000 RPM.

The sealed design keeps grease in and contaminants out, reducing maintenance needs. The phenolic cage adds strength while keeping weight low at just 0.32kg.

Ideal for precision machinery like spindles or CNC equipment, this bearing works in temperatures from -30°C to 110°C. It can be matched in sets for back-to-back, face-to-face, or tandem arrangements.
