KF120AR0 Bearing Product Overview & Core Advantages
The KF120AR0 is a high-performance thin section angular contact ball bearing designed for applications demanding high precision and compact design. Featuring a single row construction with a 30° contact angle, it is engineered to efficiently support combined loads, handling significant radial and axial loads simultaneously. Manufactured to ABEC-1 tolerance standards, this bearing offers reliable performance in space-constrained assemblies where weight and cross-section are critical factors, making it an ideal solution for high-rigidity rotary systems.
KF120AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| KF120 | Bearing series designation | Identifies the thin section bearing series with specific cross-section dimensions |
| A | Angular contact design | Optimized for combined radial and axial loads |
| R0 | Radial internal clearance designation | Specifies the precise internal clearance range for optimal performance |
KF120AR0 Bearing Structural Features & Performance Benefits
Thin Section Design: With a compact cross-section of only 0.75" width and minimal wall thickness, this bearing enables space-saving designs while maintaining structural integrity.
Premium Material Construction: Utilizing chrome steel for both rings and balls, combined with a brass cage, ensures excellent durability and consistent performance under demanding conditions.
High Load Capacity: The 30° contact angle configuration provides superior axial load capacity (16,290 lbf static) while maintaining excellent radial load handling (6,487 lbf dynamic, 17,100 lbf static).
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (±0.0014" on diameters) ensures smooth operation and precise positioning in critical applications.
Optimized Internal Clearance: The specified radial internal clearance range (0.0000 – 0.0005") provides optimal preload characteristics for enhanced system rigidity and rotational accuracy.
