Super Precision Angular Contact Ball Bearings 71920 ACEGA/HCP4AL

Super Precision Angular Contact Ball Bearings 71920 ACEGA/HCP4AL

The 71920 ACEGA/HCP4AL is a super precision angular contact ball bearing with a 100mm bore and 140mm outer diameter, crafted from chrome steel for durability. Its 25° contact angle and ceramic balls ensure smooth operation under angular loads.

This bearing handles radial loads up to 8348 lbf and spins at speeds up to 16,000 RPM, making it suitable for high-performance applications. The phenolic cage provides stability while keeping the weight low at just 0.65kg.

With an extra light preload (Class A) and P4A tolerance, it offers precise movement in demanding setups. The open design allows for easy lubrication and maintenance.

Ideal for machine tools or spindle applications, this bearing can be matched in sets of four for back-to-back, face-to-face, or tandem arrangements. It works in temperatures from -30°C to 110°C and is interchangeable with SKF models.
