KC300AR0 Bearing Product Overview & Core Advantages
The KC300AR0 is a high-precision thin section angular contact ball bearing designed for applications requiring exceptional rigidity and accurate rotational performance. As a single row bearing with a 30° contact angle, it is engineered to efficiently support combined loads, handling significant radial and axial loads simultaneously. Its Reali-Slim Open construction provides a compact cross-section, maximizing space and weight savings in precision assemblies. Manufactured to ABEC-1 tolerance standards, it delivers reliable performance for demanding, high-accuracy environments.
KC300AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KC300A | Indicates the specific thin section bearing series and size (30" bore). |
| R0 | Signifies an Open (unsealed) design, allowing for custom lubrication schemes and facilitating high-speed operation. |
KC300AR0 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 30° contact angle provides optimized support for combined loads, offering a high radial dynamic load rating of 3561 lbf and a substantial axial static load rating of 10160 lbf.
- Precision Engineering: Manufactured from Chrome Steel for rings and balls with a Brass cage, the bearing ensures durability and stable operation. Compliance with ABEC-1 precision tolerances guarantees consistent performance and interchangeability.
- Optimized for Performance: The open design allows for efficient heat dissipation and is suitable for applications where custom lubrication is preferred. The specified radial internal clearance ensures optimal preload and running accuracy.
- Extended Service Life: The robust construction and high-quality materials contribute to long-term reliability under demanding operating conditions within its temperature range of -30°C to 110°C.
