Super Precision Angular Contact Ball Bearings 7008 FE/HCP4ADBA

Super Precision Angular Contact Ball Bearings 7008 FE/HCP4ADBA

The 7008 FE/HCP4ADBA is a super precision angular contact ball bearing with a 40mm bore and 68mm outer diameter, designed for high-speed applications. It features a 18° contact angle and comes in a matched pair (DB arrangement) for balanced performance.

Made from chrome steel rings and ceramic balls, it handles radial loads up to 4388 lbf and spins smoothly at speeds up to 56,000 RPM. The phenolic cage ensures durability while keeping weight low at just 0.34kg.

Its open design allows easy lubrication, and the extra light preload (Class A) ensures minimal friction. Ideal for precision machinery like CNC spindles or high-speed motors.

The bearing operates in temperatures from -30°C to 110°C and meets P4A tolerance standards for accuracy. Interchangeable with SKF bearings, it’s a reliable choice for replacements or upgrades.
