Super Precision Angular Contact Ball Bearings S71910 ACB/HCP4ATBTB

Super Precision Angular Contact Ball Bearings S71910 ACB/HCP4ATBTB

The S71910 ACB/HCP4ATBTB 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 3510 lbf and spins smoothly at speeds up to 34,000 RPM, thanks to its phenolic cage and grease lubrication.

Its sealed design and 25° contact angle ensure stable performance, while the matched set of three bearings (arranged TBT) provides balanced load distribution. The light preload (Class B) enhances precision in demanding applications.

Ideal for high-speed machinery like spindles or CNC tools, where accuracy and reliability are crucial. With a temperature range of -30°C to 110°C, it suits various industrial environments.

Weighing 0.4kg, it’s a compact yet robust choice for precision engineering. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacements.
