KF080AR0 Bearing Product Overview & Core Advantages
The KF080AR0 is a high-performance thin-section angular contact ball bearing designed for applications demanding precision and space optimization. Engineered in inch dimensions with an 8" bore, this single-row bearing excels in handling combined radial and axial loads simultaneously, thanks to its specified 30° contact angle. Its Reali-Slim Open construction provides a compact cross-section while maintaining high load capacity, making it ideal for precision equipment and robotic applications where weight and space constraints are critical.
KF080AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| KF080 | Bore diameter identifier (8 inches) | Specifies the large bore size for shaft mounting |
| A | Angular contact design | Optimized for combined radial and axial loading |
| R0 | Reali-Slim open bearing series | Ultra-thin cross-section design for space-constrained applications |
KF080AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: The Reali-Slim construction provides a minimal cross-section (0.75" width) while maintaining structural integrity, enabling compact machine designs and weight reduction.
High Load Capacity: With a 30° contact angle and premium chrome steel components, this bearing delivers exceptional radial dynamic load rating of 5242 lbf and axial static load capacity of 12670 lbf, making it suitable for demanding applications.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore tolerance: -0.0012" to 0"), ensuring consistent performance and smooth operation in precision systems.
Enhanced Durability: The brass cage provides superior guidance and stability, while the open design allows for optimal lubrication management in high-performance systems.
