Super Precision Angular Contact Ball Bearings 7008 CE/P4ADBA

Super Precision Angular Contact Ball Bearings 7008 CE/P4ADBA

The 7008 CE/P4ADBA is a super precision angular contact ball bearing with a 40mm bore and 68mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 4478 lbf and reaches speeds of 56,000 RPM, thanks to its phenolic cage and 15° contact angle.

Its matched pair design (DB arrangement) with extra light preload ensures smooth, stable rotation for high-precision applications. The open seal allows easy lubrication, while the P4A tolerance class guarantees consistent performance.

Ideal for machine tools or spindle drives where accuracy is key, this bearing operates in temperatures from -30°C to 110°C. Weighing 0.37kg, it’s a robust yet lightweight choice for demanding setups.

Compatible with SKF equivalents, it’s a reliable option for replacements or upgrades. The 19-ball design balances load distribution for long service life.
