Super Precision Angular Contact Ball Bearings S7008 CE/P4ADBA

Super Precision Angular Contact Ball Bearings S7008 CE/P4ADBA

The S7008 CE/P4ADBA is a super precision angular contact ball bearing, measuring 40mm by 68mm by 30mm, crafted from durable chrome steel. It features a 15° contact angle and comes sealed for protection, with two bearings arranged back-to-back for stability.

This bearing handles radial loads up to 4478 lbf and spins smoothly at speeds up to 41,000 RPM, thanks to its phenolic cage and grease lubrication. Its extra-light preload ensures minimal friction during operation.

The sealed design keeps contaminants out, making it low-maintenance, while the P4A tolerance class guarantees high precision. It works reliably in temperatures from -30°C to 110°C.

Ideal for high-speed applications like machine tool spindles or precision equipment, where accuracy and durability are key. Weighing 0.38kg, it’s a robust yet lightweight solution for demanding setups.
