KF065AR0 Bearing Product Overview & Core Advantages
The KF065AR0 is a high-performance thin section angular contact ball bearing designed for applications requiring exceptional precision and load handling capabilities. This single row bearing features a 30° contact angle, enabling it to support significant combined loads—both radial and axial forces—simultaneously. Its Reali-Slim Open construction provides a compact, lightweight solution without compromising strength, making it ideal for space-constrained, high-rigidity applications. Manufactured to ABEC-1 tolerance standards, it ensures reliable performance in demanding industrial environments.

KF065AR0 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The 30° contact angle and single row design provide excellent combined load handling, with a radial dynamic load rating of 4,734 lbf and axial static load rating of 11,220 lbf.
Precision Engineering: Manufactured from chrome steel rings and balls with a brass cage, this bearing offers consistent performance under high stress. The tight radial internal clearance (0.0000 – 0.0005") ensures smooth operation and minimal vibration.
Space-Efficient Design: With a cross-section of only 0.75" and large bore diameter of 6.5", the Reali-Slim construction maximizes available space while maintaining structural integrity, offering a static load moment capacity of 28,220 lbf.
Wide Operating Range: Suitable for temperatures from -30°C to 110°C, this bearing accommodates various industrial environments when properly lubricated.
KF065AR0 Bearing Typical Application Areas
- Robotics and automation systems requiring precise motion control
- Aerospace components where weight savings and reliability are critical
