KC080AR0 Bearing Product Overview & Core Advantages
The KC080AR0 is a high-precision thin section angular contact ball bearing designed for applications demanding exceptional rigidity and accuracy within compact spaces. Manufactured to ABEC-1 tolerance standards, this single-row bearing excels at supporting combined loads, handling significant radial and axial forces simultaneously due to its specified 30° contact angle. Its Reali-Slim open construction offers a superior strength-to-cross-section ratio, making it ideal for high-reliability, weight-sensitive applications where space is at a premium.
KC080AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KC080 | Indicates the specific bearing series and size designation (8" bore). |
| A | Signifies an Angular Contact design, optimized for combined loads. |
| R0 | Denotes the Radial Internal Clearance group (0.0000 – 0.0005"). |
KC080AR0 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single-row angular contact design with a 30° contact angle provides high rigidity, enabling the bearing to support substantial combined radial and axial static loads (4950 lbf radial, 4300 lbf axial).
- Precision Thin-Section Design: As a Reali-Slim bearing, it minimizes weight and space requirements (0.375" width) without sacrificing performance, crucial for compact assemblies.
- Premium Material Construction: Components made from Chrome Steel (rings and balls) and a Brass cage ensure high strength, durability, and stable operation.
- Precision Performance: Manufactured to ABEC-1 tolerances with a controlled radial internal clearance, ensuring consistent, high-precision rotation and smooth operation.
KC080AR0 Bearing Typical Application Areas
This bearing is engineered for high-performance applications, including:
- Robotics and automation arms (for precise joint movement)
- Aerospace control mechanisms and instrumentation
- Medical Equipment such as MRI scanners and surgical robots
- Semiconductor Manufacturing equipment
- High-precision Industrial Rotating Stages and spindles
