KB035AR6 Bearing Product Overview & Core Advantages
The KB035AR6 is a high-precision thin section angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. Manufactured to ABEC 7F tolerance class, this single-row bearing excels in handling combined radial and axial loads simultaneously, thanks to its defined 30° contact angle. Its compact thin-section design (0.3125" width) provides a high load capacity within a minimal cross-section, making it ideal for space-constrained, high-performance machinery requiring superior rotational accuracy and high rigidity.
KB035AR6 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KB | Indicates the Reali-Slim series of thin section bearings. |
| 035 | Specifies the bore diameter of 3.5 inches. |
| A | Denotes the 30° contact angle, optimized for handling significant axial loads. |
| R | Signifies a Brass (machined) cage for enhanced stability and speed capability. |
| 6 | Represents the ABEC 7F precision class, ensuring extremely tight dimensional and running accuracy. |
KB035AR6 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single-row angular contact design with a 30° contact angle provides robust support against combined loads. It offers a high radial dynamic load rating of 801 lbf and a substantial axial static load rating of 1930 lbf.
- Precision Engineering: Manufactured to ABEC 7F standards with a very tight radial internal clearance (0.0000 – 0.0005"), this bearing ensures smooth, precise, and quiet operation, minimizing vibration and runout.
- Optimized Components: The use of a machined brass cage (R) ensures excellent guidance and stability at high speeds. All components, including rings and balls, are made from Chrome Steel for high durability and wear resistance.
- Thin-Section Design: The compact cross-section maximizes space efficiency without compromising on performance, allowing for lighter and more compact machine designs.
KB035AR6 Bearing Typical Application Areas
The KB035AR6 is engineered for high-performance applications where precision, rigidity, and a compact form factor are critical. Key industries and equipment include:
- Robotics and Automation: Robot arm joints, precision actuators, and rotary tables.
- Aerospace and Defense: Gyroscopes, radar platforms, and satellite positioning mechanisms.
- Medical Equipment: CT scanners, MRI machines, and surgical robot arms.
- Semiconductor Manufacturing: Wafer handling robots, precision stages, and stepper motors.
- High-Precision Machinery: Optical positioning systems, coordinate measuring machines (CMM), and high-speed spindles.
