KD200AR0 Bearing Product Overview & Core Advantages
The KD200AR0 is a high-performance thin-section angular contact ball bearing designed for applications requiring exceptional precision and space optimization. As part of the Reali-Slim Open Bearings series, it features a single-row construction with a 30° contact angle, enabling it to efficiently handle combined radial and axial loads. Its inch-dimension design (20" bore) provides a compact cross-section while maintaining high rigidity and load capacity, making it ideal for precision machinery where weight and space are critical constraints.
Model Code Deep Explanation
| Code Segment | Technical Meaning |
|---|---|
| KD200 | Bearing series designation for thin-section angular contact bearings |
| A | 30° contact angle design |
| R0 | Radial internal clearance specification (0.0000 - 0.0005") |
| Open | Unsealed construction for custom lubrication solutions |
KD200AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: With only 0.5" width and 1" radial cross-section, this bearing provides maximum space savings while maintaining structural integrity.
High Load Capacity: The 30° contact angle and precision construction deliver exceptional load ratings - 4,356 lbf dynamic and 16,190 lbf static radial load capacity, plus 11,710 lbf axial static load capacity.
Precision Performance: Manufactured to ABEC-1 tolerance class with minimal radial internal clearance (0.0000 - 0.0005") for smooth, precise operation in demanding applications.
Premium Materials: Constructed with chrome steel rings and balls with a brass cage for durability and reliable performance across the operating temperature range of -30°C to 110°C.
