Super Precision Angular Contact Ball Bearings 7008 ACE/HCP4AQBCA

Super Precision Angular Contact Ball Bearings 7008 ACE/HCP4AQBCA

The 7008 ACE/HCP4AQBCA is a super precision angular contact ball bearing with a 40mm bore and 68mm outer diameter, crafted from high-quality chrome steel. Its 25° contact angle and ceramic balls ensure smooth operation under radial loads up to 6908 lbf.

This set includes four matched bearings with an extra-light preload, ideal for high-speed applications reaching 56,000 RPM. The phenolic cage adds durability while keeping the weight at just 0.68kg.

The open design allows for easy lubrication, and it performs reliably in temperatures from -30°C to 110°C. Perfect for precision machinery like spindles or CNC equipment where accuracy is key.

Interchangeable with SKF bearings, this P4A-class model offers a practical solution for demanding industrial setups. Its compact size (40mm×68mm×60mm) fits neatly into tight spaces without sacrificing performance.
