Super Precision Angular Contact Ball Bearings S7012 CE/HCP4A

Super Precision Angular Contact Ball Bearings S7012 CE/HCP4A

The S7012 CE/HCP4A is a super precision angular contact ball bearing with a 60mm bore and 95mm outer diameter, crafted from durable chrome steel. Its 15° contact angle efficiently manages combined radial and thrust loads, while the ceramic balls reduce friction for smoother operation.

This sealed unit comes pre-lubricated and can handle speeds up to 24,000 RPM, making it suitable for high-performance applications. The phenolic cage ensures quiet running and long service life, even in temperatures ranging from -30°C to 110°C.

With a P4 tolerance class (equivalent to ABEC-7), it offers exceptional accuracy for precision machinery. Ideal for use in spindle drives, machine tools, or other applications demanding high-speed and precise motion control.

Weighing just 0.4kg, it’s lightweight yet robust, and can be matched with other bearings for specific preload requirements. Interchangeable with SKF bearings, it’s a reliable choice for replacements or upgrades.
