KG200AR0 Bearing Product Overview & Core Advantages
The KG200AR0 is a high-performance thin section angular contact ball bearing designed for applications demanding exceptional precision and rigidity. Engineered with a single row construction and a 30° contact angle, this bearing excels at supporting combined loads, simultaneously handling significant radial and axial forces. Its large 20-inch bore and compact 1-inch width in an open design make it ideal for space-constrained, high-precision machinery requiring reliable performance under demanding conditions.
KG200AR0 Bearing Model Code Explained, Specifications & Naming Convention
The KG200AR0 model code provides specific technical information:
- KG200: Denotes the specific bearing series and size designation.
- A: Signifies the Angular Contact design.
- R0: Indicates the Radial Internal Clearance group (0.0000 – 0.0005").
KG200AR0 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 loads, as evidenced by its high radial dynamic load rating of 13,612 lbf and axial static load rating of 35,490 lbf.
- Precision Performance: Manufactured to ABEC-1 tolerance standards, this bearing ensures smooth, precise operation essential for accurate positioning and minimal runout.
- Optimized Material Selection: The use of Chrome Steel for rings and balls, combined with a Brass cage, ensures durability, high-speed capability, and long service life.
- Controlled Internal Clearance: The specified radial internal clearance (R0 group) is critical for optimal performance, managing operational heat and preload in the application.
KG200AR0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring large diameters, thin cross-sections, and high precision, such as:
- Robotics and Automation Arms
- Precision Rotary Tables and Indexers
- Aerospace Actuation Systems
- Medical Imaging Equipment (e.g., CT Scanners)
- Semiconductor Manufacturing Equipment
