JB055CP0 Bearing Product Overview & Core Advantages
The JB055CP0 is a thin section sealed ball bearing from the Reali-Slim series, engineered for applications requiring compact design and reliable performance in limited spaces. This single row bearing features a sealed construction and is pre-lubricated, making it suitable for radial load applications where minimal cross-section is critical. Its inch-dimension design with a 5.5" bore provides high precision and consistent operation, ideal for precision machinery and motion control systems demanding ABEC-1 tolerance standards.
JB055CP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| JB055 | Bearing series designation for Reali-Slim sealed bearings with 5.5" bore diameter | Identifies the thin-section bearing family and size specification |
| C | Radial internal clearance specification | Optimized clearance (0.0000 – 0.0005") for precise operation |
| P0 | ABEC-1 tolerance class equivalent | Standard precision grade for general industrial applications |
JB055CP0 Bearing Structural Features & Performance Benefits
Thin Section Design: With only 0.3125" width and minimal cross-section, this bearing enables compact machine designs while maintaining structural integrity. The optimized bearing dimensions (5.5" bore × 6.125" OD) provide maximum space utilization.
Sealed Construction: Integrated seals protect against contamination while retaining lubrication, extending service life in demanding environments. The brass cage material ensures smooth operation and reliable ball guidance.
Premium Material Selection: Constructed from chrome steel for both rings and balls, delivering excellent wear resistance and durability. The combination provides a radial dynamic load rating of 984 lbf and static load capacity of 2360 lbf.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore tolerance: -0.0010"– 0"), ensuring consistent performance and easy installation in precision assemblies.
