| Code Segment | Technical Meaning |
|---|---|
| KB | Indicates the Reali-Slim® series of thin section bearings. |
| 030 | Specifies the bore diameter in inches (3.0"). |
| C | Denotes the cross-section type (specific to the Reali-Slim sizing system). |
| P | Specifies the bearing's radial internal clearance. |
| 0 | Indicates the open (unsealed) construction, allowing for custom lubrication or high-speed applications. |
KB030CP0 Bearing Structural Features & Performance Benefits
- Space-Saving Thin Section Design: With a minimal width of 0.3125", this bearing enables compact and lightweight assemblies without sacrificing performance, making it ideal for applications with strict size constraints.
- High Radial Load Capacity: The single-row construction with a full complement of chrome steel balls provides a dynamic load rating of 707 lbf and a static load rating of 1340 lbf, ensuring reliable operation under significant radial stress.
- Precision Performance: Built to ABEC-1 precision standards with tight bore and OD tolerances, it guarantees smooth, low-vibration rotation essential for accurate positioning systems.
- Optimized Material Selection: The combination of a chrome steel ring and brass cage offers excellent durability and stable operation across the specified temperature range (-30°C to 110°C).
- Flexible Lubrication: The open seal type allows for the use of specialized lubricants tailored to specific operational environments, from high-speed to extreme temperatures.
