KC055CP0 Bearing Product Overview & Core Advantages
The KC055CP0 is a high-performance thin-section open bearing designed for applications requiring compact design and precise radial load capacity. As part of the Reali-Slim Open Bearings series with inch measurement system, this single-row ball bearing features an exceptionally thin cross-section relative to its bore diameter, enabling significant space and weight savings in precision machinery. Manufactured to ABEC-1 tolerance class, it delivers reliable performance in applications demanding high rotational accuracy and consistent operation.
KC055CP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| KC | Reali-Slim Series Identifier | Indicates thin-section bearing construction |
| 055 | Bore Diameter: 5.5 inches | Large bore size for shaft mounting |
| C | Cross Section: 0.187" (R Series) | Ultra-thin radial section profile |
| P0 | ABEC-1 Precision Class | Standard precision for general applications |
| Open Construction | No seals or shields | Allows for custom lubrication schemes |
KC055CP0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With a cross-section of only 0.375" and consistent radial thickness, this bearing enables compact machine designs while maintaining structural integrity. The optimized geometry provides excellent space utilization in applications where envelope constraints are critical.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, combined with a brass cage, this bearing delivers superior wear resistance and dimensional stability. The brass cage ensures smooth operation at moderate speeds and provides excellent guidance for the ball complement.
Precision Engineering: The ABEC-1 tolerance class and tight dimensional controls (bore tolerance: -0.0010"–0", OD tolerance: -0.0010"–0") guarantee consistent performance and reliable fitment in precision assemblies. The controlled radial internal clearance (0.0000 – 0.0005") ensures optimal preload conditions.
Load Capacity: With a dynamic radial load rating of 1274 lbf and static radial load rating of 2830 lbf, this bearing handles significant radial loads while maintaining smooth operation. The ISO radial rating of 2594 lbf confirms its robust performance capabilities.
