Super Precision Angular Contact Ball Bearings S7012 ACE/HCP4ATBTA

Super Precision Angular Contact Ball Bearings S7012 ACE/HCP4ATBTA

The S7012 ACE/HCP4ATBTA is a super precision angular contact ball bearing with a 60mm bore and 95mm outer diameter, crafted from chrome steel for durability. It features a 25° contact angle and comes sealed for protection, with three matched bearings in a TBT arrangement.

This bearing handles radial loads up to 7898 lbf and spins smoothly at speeds up to 31,000 RPM, thanks to its ceramic balls and phenolic cage. The extra-light preload ensures minimal friction during operation.

Its sealed design keeps grease in and contaminants out, making it low-maintenance. Ideal for high-speed applications like machine tool spindles or precision equipment where accuracy is key.

Weighing 1.2kg, it operates reliably in temperatures from -30°C to 110°C. The P4A tolerance class guarantees consistent performance, while its compatibility with SKF bearings simplifies replacements.
