KG050AR0 Bearing Product Overview & Core Advantages
The KG050AR0 is a thin-section angular contact ball bearing engineered for applications demanding high precision and space optimization. This single-row bearing is designed to accommodate combined loads, efficiently handling significant axial static loads in one direction alongside radial loads. Its 30° contact angle and ABEC-1 precision class make it an ideal solution for high-rigidity, moderate-speed systems requiring reliable performance in a compact envelope.
KG050AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KG050AR0 | Model designation for this specific thin-section angular contact bearing series. |
| Open (Seal Type) | Unsealed construction, allowing for custom lubrication schemes and enabling higher potential speeds in clean environments. |
| Lubricated | Factory pre-lubricated, ensuring immediate operation and reducing initial setup complexity. |
KG050AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides excellent resistance to combined loads, supporting a high axial static load rating of 15,400 lbf and a radial static load rating of 11,370 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with a controlled radial internal clearance (0.0000 – 0.0005"), ensuring smooth, precise rotation and reduced vibration.
- Optimized Material Selection: Components made from Chrome Steel (rings and balls) and a Brass cage offer high durability, corrosion resistance, and stable operation across a wide temperature range (-30°C to 110°C).
- Space-Saving Design: As part of the Reali-Slim Open Bearings family, it features a thin cross-section (1" width with 5" bore), enabling compact and lightweight machinery designs without sacrificing performance.
KG050AR0 Bearing Typical Application Areas
This bearing is suited for high-performance applications where space, weight, and precision are critical. Key industries and equipment include:
- Robotics and Automation: Robot arm joints, rotary actuators.
- Aerospace & Defense: Gyroscopes, radar platforms, control surface mechanisms.
- Medical Equipment: CT scanner gantries, surgical robot joints.
