Super Precision Angular Contact Ball Bearings 71915 ACD/HCPA9ADT

Super Precision Angular Contact Ball Bearings 71915 ACD/HCPA9ADT

The 71915 ACD/HCPA9ADT is a super precision angular contact ball bearing with a 75mm bore and 105mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 12442 lbf and reaches speeds of 22000 RPM, thanks to its ceramic balls and phenolic cage.

Its 25° contact angle and matched arrangement (2 bearings << DT) ensure stable performance under angular loads. The open design allows easy lubrication, while the PA9A tolerance class guarantees high precision. This bearing operates smoothly in temperatures from -30°C to 110°C, making it suitable for demanding applications like machine tool spindles or high-speed robotics. Weighing 0.6kg, it’s lightweight yet robust for its size. Interchangeable with SKF bearings, it’s a reliable choice for replacements or upgrades. Ideal for scenarios where precision and speed are critical.
