Super Precision Angular Contact Ball Bearings S7013 CDGA/HCP4A

Super Precision Angular Contact Ball Bearings S7013 CDGA/HCP4A

The S7013 CDGA/HCP4A is a super precision angular contact ball bearing with a 65mm bore and 100mm outer diameter, crafted from high-quality chrome steel. Its compact 18mm width makes it suitable for tight spaces while maintaining robust performance.

This bearing handles radial loads up to 9360 lbf and achieves impressive speeds of 36,000 RPM, thanks to its ceramic balls and phenolic cage. The 15° contact angle ensures smooth operation under angular loads, with extra light preload for precision applications.

Sealed for protection, it comes pre-lubricated with grease and operates efficiently in temperatures from -30°C to 110°C. The P4A tolerance class guarantees high accuracy, ideal for demanding machinery.

Universal matching allows flexible arrangements like back-to-back or tandem setups. Weighing 0.37kg, it’s a reliable choice for spindle drives or high-speed rotary systems where precision is key. Interchangeable with SKF bearings for easy replacement.
