Super Precision Angular Contact Ball Bearings S71915 ACEGA/HCP4A

Super Precision Angular Contact Ball Bearings S71915 ACEGA/HCP4A

The S71915 ACEGA/HCP4A is a super precision angular contact ball bearing with a 75mm bore and 105mm outer diameter, crafted from chrome steel for durability. Its 25° contact angle and ceramic balls ensure smooth operation under angular loads.

This sealed bearing handles dynamic radial loads up to 4770 lbf and spins at speeds up to 28,000 RPM. The phenolic cage and grease lubrication make it low-maintenance and long-lasting in temperatures from -30°C to 110°C.

With a P4A tolerance class, it offers high precision for demanding applications. The bearing comes in matched sets of two, suitable for back-to-back, face-to-face, or tandem arrangements.

Ideal for high-speed machinery like spindles or robotics, where precision and reliability are key. Weighing just 0.29kg, it’s lightweight yet robust for its size.
