Super Precision Angular Contact Ball Bearings 71907 CD/P4ADBA

Super Precision Angular Contact Ball Bearings 71907 CD/P4ADBA

The 71907 CD/P4ADBA is a super precision angular contact ball bearing with a 35mm bore and 55mm outer diameter, crafted from durable chrome steel. It features a 15° contact angle and comes in a matched pair for balanced performance.

This bearing handles radial loads up to 3578 lbf and reaches speeds of 56,000 RPM, making it suitable for high-speed applications. Its phenolic cage ensures smooth operation and reduces friction.

The open design allows for easy lubrication, while the extra light preload (Class A) ensures precise alignment. It operates reliably in temperatures from -30°C to 110°C.

Ideal for precision machinery like spindles or CNC tools, where accuracy and speed are crucial. Weighing just 0.15kg, it’s lightweight yet robust. Compliant with P4A tolerance standards for high precision.

Interchangeable with SKF bearings, it’s a practical choice for replacements or upgrades. The matched pair setup (DB arrangement) provides stability under angular loads.
