KC090CP0 Bearing Product Overview & Core Advantages
The KC090CP0 is a thin-section open bearing engineered for applications demanding space optimization without compromising performance. As part of the Reali-Slim series, this single-row ball bearing is designed to handle significant radial loads within a compact cross-section. Its open construction allows for custom lubrication schemes and facilitates easy inspection, making it ideal for high-precision machinery where weight and space are critical constraints. Manufactured to ABEC-1 precision tolerances, it ensures reliable operation and consistent performance.
KC090CP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KC090 | Indicates the specific Reali-Slim series bearing size with a 9" bore diameter. |
| C | Specifies the radial internal clearance group (C3 equivalent: 0.0000 – 0.0005"). |
| P | Denotes the bearing is lubricated from the factory. |
| 0 | Identifies the contact angle and specific internal design configuration. |
KC090CP0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: With a consistent cross-section (0.375" width relative to 9" bore), this bearing delivers maximum load capacity in minimal space, enabling lightweight and compact machinery designs.
Superior Load Handling: The single-row deep groove ball bearing construction provides a high radial dynamic load rating of 1678 lbf and an exceptional radial static load rating of 4510 lbf, ensuring durability under demanding conditions.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore/OD tolerance: -0.0012"– 0"), guaranteeing smooth operation and reduced vibration in precision applications.
Advanced Material Selection: Chrome steel rings and balls provide excellent wear resistance, while the brass cage ensures stable ball guidance and reliable performance at moderate speeds.
Controlled Internal Clearance: The specified radial internal clearance (0.0000 – 0.0005") allows for precise fitment and optimal performance under various operating conditions.
KC090CP0 Bearing Typical Application Areas
- Robotics and Automation: Joint bearings in robotic arms and automation equipment where space and weight are critical
