KC200AR0 Bearing Product Overview & Core Advantages
The KC200AR0 is a high-performance thin-section angular contact ball bearing designed for applications demanding exceptional precision and space optimization. As part of the Reali-Slim Open Bearings series, this single-row bearing excels in handling combined radial and axial loads simultaneously, thanks to its defined 30° contact angle. Its inch-series construction with a large 20-inch bore and remarkably slim 0.375-inch cross-section makes it an ideal solution for compact, high-rigidity designs in robotics, aerospace, and precision machinery where weight and space are critical constraints.
KC200AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit/Feature |
|---|---|---|
| KC200 | Series designation for Reali-Slim angular contact bearings | Identifies the thin-section bearing family and size |
| A | Angular Contact design | Optimized for combined radial and axial loading |
| R0 | Open (unsealed) construction | Allows for custom lubrication schemes and maximum speed capability |
KC200AR0 Bearing Structural Features & Performance Benefits
Premium Material Construction: Manufactured from chrome steel for both rings and balls, ensuring high durability and wear resistance. The brass cage provides excellent stability and guidance at high speeds.
High Load Capacity: With a radial dynamic load rating of 2863 lbf and axial static load rating of 7780 lbf, this bearing delivers reliable performance under significant combined loads. The 30° contact angle is optimally balanced for axial load support while maintaining radial load capability.
Precision Engineering: Built to ABEC-1 tolerance class with tight dimensional controls (bore and OD tolerance: -0.0018" to 0"), ensuring consistent performance and easy integration into precision assemblies. The minimal radial internal clearance (0.0000 – 0.0005") provides precise rotational accuracy.
Space-Optimized Design: The thin-section bearing configuration with only 0.375" width enables compact machine designs without compromising on load capacity or performance.
KC200AR0 Bearing Typical Application Areas
- Robotics: Robot arm joints, rotary actuators, and precision positioning systems
- Aerospace: Aircraft control mechanisms, satellite positioning systems, and aerospace instrumentation
- Medical Equipment: CT scanners, MRI systems, and surgical robot joints requiring high precision
