K34013AR0 Bearing Product Overview & Core Advantages
The K34013AR0 is a metric thin-section angular contact ball bearing engineered for applications demanding high precision and space optimization. This single-row bearing features a 30° contact angle, enabling it to support significant combined loads—both radial and axial—simultaneously. Its Reali-Slim design provides a large bore diameter relative to its cross-section, making it ideal for compact, weight-sensitive assemblies requiring high rotational accuracy and high rigidity.
K34013AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K34013 | Basic bearing designation indicating a metric thin-section bearing with a 340mm bore and 13mm width. |
| A | Signifies a 30° contact angle, optimized for handling high axial loads in one direction. |
| R0 | Indicates a specific radial internal clearance group (0.0000 – 0.0005") for precision applications. |
K34013AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides excellent resistance to combined loads. It offers a high radial dynamic load rating of 4361 lbf and a substantial axial static load rating of 11060 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance class with a very tight radial internal clearance, ensuring smooth, precise operation and minimal runout.
- Premium Material Construction: Features rings and balls made from Chrome Steel for high durability and wear resistance. The brass cage ensures stable operation under high-speed conditions.
- Optimized for Thin-Section Applications: The Reali-Slim construction delivers a high bore-to-cross-section ratio, saving space and weight (only 1.02 kg) without compromising performance.
K34013AR0 Bearing Typical Application Areas
This bearing is ideally suited for high-precision machinery and systems where space and weight are critical constraints. Common applications include:
- Robotics and Automation: Rotary joints and arm assemblies.
- Aerospace & Defense: Gyroscopes, radar platforms, and control surface actuators.
- Medical Equipment: CT scanners, MRI machines, and surgical robots.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
