Super Precision Angular Contact Ball Bearings 71915 ACD/P4ATBTB

Super Precision Angular Contact Ball Bearings 71915 ACD/P4ATBTB

The 71915 ACD/P4ATBTB is a super precision angular contact ball bearing with a 75mm bore and 105mm outer diameter, crafted from high-quality chrome steel. It handles both radial and angular loads, with a dynamic radial load capacity of 16380 lbf.

Its 25° contact angle and matched set of three bearings (arranged > TBT) ensure smooth operation at speeds up to 22000 RPM. The phenolic cage offers durability while keeping the weight light at 1.05kg.

Designed for precision applications, this bearing works well in temperatures from -30°C to 110°C. Ideal for machine tools or high-speed spindles where accuracy and reliability are key.

The open design allows for easy lubrication, and its P4A tolerance class guarantees consistent performance. Interchangeable with SKF bearings, it’s a practical choice for replacements or upgrades.
