KF400AR0 Bearing Product Overview & Core Advantages
The KF400AR0 is a high-precision thin section angular contact ball bearing designed for applications demanding exceptional rigidity and precise motion control. Engineered with a 30° contact angle and a single-row design, it is optimized to support combined loads, handling significant radial loads alongside thrust loads in one direction. Its Reali-Slim open construction offers a compact, lightweight solution, making it ideal for space-constrained, high-performance systems requiring ABEC-1 precision and reliable operation.
KF400AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KF400 | Indicates the specific bearing series and size designation for thin section bearings. |
| A | Signifies the 30° contact angle, which is optimized for handling high axial loads. |
| R0 | Denotes a specific internal design and radial internal clearance group (0.0000" – 0.0005"). |
KF400AR0 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 (Radial Dynamic: 12,147 lbf, Axial Static: 35,580 lbf).
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (Bore/OD tolerance: -0.0020"– 0"), ensuring smooth, precise rotation and minimal runout for high-accuracy applications.
- Optimized Material Construction: Features rings and balls made from Chrome Steel for durability and wear resistance, combined with a Brass cage for superior guidance and stability at moderate speeds.
- Compact and Lightweight: As part of the Reali-Slim series, it offers a minimal cross-section (Width: 0.75") relative to its bore diameter, reducing system weight and enabling compact design solutions.
KF400AR0 Bearing Typical Application Areas
The KF400AR0 is ideally suited for precision machinery and systems where space, weight, and accuracy are critical. Common applications include:
- Robotics and Automation arms and joints
- Aerospace control mechanisms and gimbals
- Medical Equipment such as scanners and surgical robots
- Semiconductor Manufacturing equipment
- Precision Rotary Tables and indexing heads
