K32013AR0 Bearing Product Overview & Core Advantages
The K32013AR0 is a single row angular contact ball bearing from the Reali-Slim mm Metric series of thin section bearings. Engineered for applications requiring high precision and space-saving designs, this bearing excels at handling combined loads, supporting significant radial loads alongside thrust loads in one direction due to its 30° contact angle. Its compact cross-section (13 mm width) and ABEC-1 precision make it ideal for high-accuracy, lightweight systems demanding reliable performance.

| Code Segment | Technical Meaning |
|---|---|
| K | Part of the Reali-Slim metric thin-section bearing series designation. |
| 32013 | Specifies the bore diameter (320 mm) and cross-section. |
| A | Indicates a 30° contact angle, optimized for high thrust load capacity. |
| R0 | Specifies a standard radial internal clearance (0.0000 – 0.0005"). |
K32013AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: The single-row construction with a 13 mm width provides a compact, lightweight solution without sacrificing performance, crucial for reducing overall system size and weight.
High Load Capacity: The 30° contact angle and robust construction using chrome steel rings and balls enable the bearing to handle high combined radial and axial loads, with a radial dynamic load rating of 4197 lbf and an axial static load rating of 10591 lbf.
Precision & Rigidity: Manufactured to ABEC-1 tolerance class, this bearing ensures smooth, precise operation. The brass cage provides excellent stability and guidance for the balls, contributing to reliable high-speed capability and low noise.
Standard Lubrication & Open Design: The bearing comes lubricated and features an open seal type, allowing for easy re-lubrication and customization in controlled environments, supporting a temperature range of -30°C to 110°C.
K32013AR0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and precision positioning systems.
- Aerospace & Defense: Guidance systems, radar platforms, and actuation mechanisms.
- Medical Equipment: MRI and CT scanner gantries, surgical robots.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
