Super Precision Angular Contact Ball Bearings 71911 FE/HCP4ALDGA

Super Precision Angular Contact Ball Bearings 71911 FE/HCP4ALDGA

The 71911 FE/HCP4ALDGA is a super precision angular contact ball bearing with a 55mm bore and 80mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 5648 lbf and reaches speeds of 34,000 RPM, making it suitable for high-performance applications.

Its open design and phenolic cage ensure smooth operation, while the extra-light preload (Class A) minimises friction. The bearing operates efficiently in temperatures from -30°C to 110°C.

This model comes in a matched set of two, allowing universal mounting (back-to-back, face-to-face, or tandem). Ideal for precision machinery like spindles or CNC equipment where accuracy is key.

Weighing just 0.29kg, it’s lightweight yet robust. Compliant with P4A tolerance standards for reliable performance. Interchangeable with SKF bearings for easy replacements.
