Super Precision Angular Contact Ball Bearings S7005 ACE/HCP4ADGA

Super Precision Angular Contact Ball Bearings S7005 ACE/HCP4ADGA

The S7005 ACE/HCP4ADGA is a super precision angular contact ball bearing, measuring 25mm by 47mm by 24mm. It’s crafted from chrome steel with ceramic balls for smooth operation and a phenolic cage for durability.

With a 25° contact angle, it handles radial loads up to 2858 lbf and spins at speeds up to 83,000 RPM. The sealed design keeps grease in place, reducing maintenance needs.

This bearing comes in a matched set of two, suitable for universal mounting (back-to-back, face-to-face, or tandem). Its extra-light preload ensures minimal friction during high-speed use.

Ideal for precision applications like machine tool spindles or high-performance motors. Compliant with P4A tolerance standards for reliable accuracy. Weighs just 0.14kg, making it lightweight yet robust.
