KG100AR0 Bearing Product Overview & Core Advantages
The KG100AR0 is a high-performance thin section angular contact ball bearing engineered for applications demanding exceptional precision and load-handling capabilities in a compact envelope. Manufactured to ABEC-1 precision standards, this single-row bearing is specifically designed to accommodate combined radial and axial loads simultaneously, thanks to its defined 30° contact angle. Its Reali-Slim open construction offers a significant reduction in weight and cross-section without compromising strength, making it an ideal solution for space-constrained, high-rigidity systems requiring reliable performance.
KG100AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KG100AR0 | Manufacturer's specific model designation for this thin-section, angular contact bearing series. |
| Open | Indicates the bearing has no integral seals or shields, allowing for custom lubrication schemes and minimizing friction for higher potential speeds. |
| ABEC-1 | Specifies the precision tolerance class, ensuring consistent running accuracy and reduced vibration. |
KG100AR0 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row angular contact design with a 30° contact angle is optimized to support substantial combined loads. It offers a high radial dynamic load rating of 9561 lbf and a significant axial static load rating of 23060 lbf, providing robust support in demanding applications.
- Precision Engineering: Manufactured from chrome steel for both rings and balls, and featuring a brass cage, this bearing ensures smooth operation, high durability, and extended service life. The tight radial internal clearance (0.0000 – 0.0005") contributes to precise shaft positioning and low runout.
- Space and Weight Savings: As part of the Reali-Slim series, it features a large 10" bore within a compact 12" O.D. and 1" width cross-section. This design maximizes the bore size while minimizing the overall envelope and weight (8 lbs), which is critical for robotics, aerospace, and semiconductor equipment.
- Versatile Operation: The open, lubricated design allows for a broad operating temperature range from -30°C to 110°C, ensuring performance stability across various environmental conditions.
KG100AR0 Bearing Typical Application Areas
This bearing is ideally suited for high-performance machinery where precision, a slim profile, and high load capacity are paramount. Key industries and equipment include:
- Robotics: Robotic arms, rotary joints, and precision actuators.
- Aerospace & Defense: Radar platforms, gimbal systems, and flight control mechanisms.
- Semiconductor Manufacturing: Wafer handling robots, stepper stages, and precision positioning tables.
- Medical Equipment: CT scanners, MRI machines, and surgical robotics.
- Industrial Automation: Rotary index tables, CNC rotary axes, and high-speed pick-and-place units.
