KC050AR6 Bearing Product Overview & Core Advantages
The KC050AR6 is a high-precision Angular Contact Ball Bearing engineered for demanding applications requiring exceptional accuracy and reliability. Manufactured to ABEC 7F tolerance standards, this bearing is designed to accommodate combined loads, handling significant radial and axial static loads simultaneously. Its inch-series dimensions (5" bore) and compact thin-section design make it an ideal solution for space-constrained, high-performance assemblies where rigidity and precise rotational motion are critical.
KC050AR6 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KC050 | Product series identifier for this specific thin-section angular contact bearing. |
| A | Indicates the 30° contact angle, optimized for supporting high axial loads. |
| R6 | Specifies the radial internal clearance group (0.0000 – 0.0005"), ensuring precise fit and optimal performance. |
| Open | Denotes an unsealed (Open) construction, allowing for custom lubrication schemes and high-speed operation. |
KC050AR6 Bearing Structural Features & Performance Benefits
High-Precision Construction: Built with Chrome Steel rings and balls, and a Brass cage, the KC050AR6 delivers consistent performance and long service life. The ABEC 7F precision grade guarantees tight dimensional tolerances and minimal runout.
Superior Load Capacity: The 30° contact angle and robust single-row design enable the bearing to support a high axial static load rating of 3200 lbf and a radial dynamic load rating of 1313 lbf, making it suitable for applications with significant combined loads.
Optimized for High-Speed & Rigidity: The open design, combined with the precision-ground components, facilitates efficient lubrication and heat dissipation, supporting high-speed operation. The compact cross-section contributes to a high rigidity system, minimizing deflection under load.
Pre-Configured Performance: The bearing comes lubricated from the factory and is designed for a wide operating temperature range of -30°C to 110°C, ensuring immediate readiness for installation and reliable operation in various environments.
