KF050AR0 Bearing Product Overview & Core Advantages
The KF050AR0 is a high-performance thin section angular contact ball bearing designed for applications requiring exceptional precision and space optimization. This single row bearing features a 30° contact angle, enabling it to support significant combined loads—both radial and axial. Manufactured to ABEC-1 precision standards, it delivers reliable performance in compact envelopes, making it ideal for high-rigidity systems where accuracy and high load capacity are critical.

KF050AR0 Bearing Structural Features & Performance Benefits
Engineered for superior performance, the KF050AR0's thin section construction (0.75" width) minimizes system weight and space requirements without compromising strength. The 30° contact angle and single row design provide optimal stiffness and moment load capacity (21,870 lbf), ensuring stable operation under complex loading conditions. The brass cage enhances guidance and durability, while the ABEC-1 precision and tight radial internal clearance (0.0000 – 0.0005") contribute to smooth, precise rotation. The open design allows for custom lubrication schemes, supporting operation across a temperature range of -30°C to 110°C.
