Super Precision Angular Contact Ball Bearings S71914 ACB/HCP4ATGA

Super Precision Angular Contact Ball Bearings S71914 ACB/HCP4ATGA

The S71914 ACB/HCP4ATGA is a super precision angular contact ball bearing with a 70mm bore and 100mm outer diameter, crafted from high-quality chrome steel. Its compact size (70mm×100mm×48mm) makes it suitable for tight spaces while maintaining robust performance.

With a 25° contact angle and ceramic balls, it handles radial loads up to 6322 lbf and spins smoothly at speeds up to 22,000 RPM. The phenolic cage ensures durability, and the sealed design keeps grease in place for long-term use.

This bearing comes in a matched set of three, offering flexibility for universal matching in back-to-back, face-to-face, or tandem arrangements. Ideal for high-speed applications like machine tool spindles or precision instruments.

Weighing 1.03kg, it operates efficiently in temperatures from -30°C to 110°C. Compliant with P4A tolerance standards, it’s a reliable choice for demanding engineering tasks.
