Super Precision Angular Contact Ball Bearings S7013 CD/P4A

Super Precision Angular Contact Ball Bearings S7013 CD/P4A

The S7013 CD/P4A is a super precision angular contact ball bearing with a 65mm bore and 100mm outer diameter, crafted from high-quality chrome steel. It handles radial loads up to 9360 lbf and operates smoothly at speeds up to 14,000 RPM.

Its sealed design keeps lubrication in and contaminants out, while the phenolic cage ensures quiet, efficient performance. The 15° contact angle makes it ideal for handling combined radial and axial loads.

This bearing is available with preload and matched arrangements, offering flexibility for precise applications. It works reliably in temperatures from -30°C to 110°C and meets P4 tolerance standards for high accuracy.

Weighing 0.43kg, it’s a robust choice for machine tools, spindles, or other high-speed equipment where precision is key. Interchangeable with SKF bearings, it simplifies replacements.
