KC047AR0 Bearing Product Overview & Core Advantages
The KC047AR0 is a thin-section angular contact ball bearing designed for applications requiring high precision and compact design. As part of the Reali-Slim Open series with inch measurements, this single-row bearing excels in handling combined loads through its specific 30° contact angle, providing excellent performance in both radial and axial directions. Its ABEC-1 precision and optimized internal geometry ensure reliable operation in space-constrained applications where weight reduction and dimensional accuracy are critical.
KC047AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Impact |
|---|---|---|
| KC047 | Bearing series designation for thin-section design | Enables compact, lightweight construction |
| A | Angular contact design | Optimized for combined radial and axial loads |
| R0 | Radial internal clearance specification | Ensures precise fit and optimal performance |
KC047AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With a consistent 0.375" cross-section regardless of bore size, this bearing enables space-saving solutions while maintaining structural integrity. The optimized cross-section provides excellent stiffness-to-weight ratio.
Angular Contact Configuration: The 30° contact angle and single-row construction deliver superior combined load capacity, making it ideal for applications experiencing both radial and axial forces simultaneously.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with chrome steel rings and balls, combined with a brass cage for stable operation and extended service life. The controlled radial internal clearance (0.0000 – 0.0005") ensures predictable performance.
High Load Capacity: Despite its slim profile, the bearing offers substantial load ratings with 1274 lbf dynamic and 3020 lbf static radial capacity, plus 3100 lbf axial static load capability.
