Super Precision Angular Contact Ball Bearings 71910 ACE/HCP4ALDBA

Super Precision Angular Contact Ball Bearings 71910 ACE/HCP4ALDBA

The 71910 ACE/HCP4ALDBA is a super precision angular contact ball bearing with a 50mm bore and 72mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 4478 lbf and reaches speeds of 46,000 RPM, making it suitable for high-performance applications.

Its open design and phenolic cage ensure smooth operation, while the 25° contact angle provides excellent stability under angular loads. The extra-light preload (Class A) reduces friction for enhanced efficiency.

This matched set of two bearings (DB arrangement) is ideal for precision machinery like spindles or CNC tools. It operates in temperatures from -30°C to 110°C and weighs just 0.22kg.

Compatible with SKF bearings, it’s a reliable choice for replacements or upgrades in demanding environments. The P4A tolerance class guarantees exceptional accuracy for critical tasks.
