Super Precision Angular Contact Ball Bearings S7008 CDGC/P4A

Super Precision Angular Contact Ball Bearings S7008 CDGC/P4A

The S7008 CDGC/P4A is a super precision angular contact ball bearing with a 40mm bore and 68mm outer diameter, crafted from durable chrome steel. Its 15° contact angle and sealed design ensure smooth operation under angular loads.

This bearing handles dynamic radial loads up to 3780 lbf and spins at speeds up to 41,000 RPM, thanks to its phenolic cage and grease lubrication. It performs reliably in temperatures from -30°C to 110°C.

The P4A tolerance class offers high precision, while the universal matching allows flexible arrangements (back-to-back, face-to-face, or tandem). Weighing just 0.19kg, it’s lightweight yet robust.

Ideal for high-speed applications like machine tool spindles or precision equipment where accuracy and durability are key. Compatible with SKF bearings for easy replacement.
