K09013AR0 Bearing Product Overview & Core Advantages
The K09013AR0 is a high-precision Angular Contact Ball Bearing designed for applications requiring exceptional accuracy and reliability. This single row metric bearing features a compact thin-section design (13mm width) with a 90mm bore, making it ideal for space-constrained installations. Its primary advantage lies in its ability to support combined loads, efficiently handling both radial forces and substantial thrust loads in one direction due to its specified 30° contact angle. Manufactured to ABEC-1 tolerance standards, it ensures consistent performance in precision machinery.
K09013AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K09013 | Indicates the bearing series and size: 90mm bore, 116mm outside diameter, 13mm width. |
| A | Signifies a 30° contact angle, optimized for handling high axial loads. |
| R0 | Specifies the radial internal clearance group (0.0000 – 0.0005"), which is a premium grade for high-precision applications requiring minimal play. |
K09013AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design, combined with a 30° contact angle and a robust brass cage, provides high rigidity. This enables the bearing to support significant combined radial and axial loads, with a static axial load rating of 4828 lbf.
- Precision Performance: Manufactured from chrome steel for both rings and balls and built to ABEC-1 precision tolerances, it ensures smooth operation, low noise, and minimal vibration, which is critical for high-speed and high-accuracy applications.
- Optimized for Thin-Section Applications: The Reali-Slim cross-section provides a high load capacity relative to its small cross-sectional size, saving space and weight (only 0.31 kg) without sacrificing performance.
- Standard Lubrication & Temperature Range: The bearing comes pre-lubricated and operates effectively within a temperature range of -30°C to 110°C, suitable for a wide array of industrial environments.
K09013AR0 Bearing Typical Application Areas
This bearing is engineered for use in precision equipment and machinery where space and weight are at a premium, and high reliability is required. Key applications include:
- Robotics and automation arms (for joint and actuator support)
- Medical Equipment such as MRI scanners and surgical robots
