K08013AR0 Bearing Product Overview & Core Advantages
The K08013AR0 is a metric thin-section angular contact ball bearing from the Reali-Slim mm series. Engineered for applications demanding high precision and space-saving designs, this single-row bearing excels at handling combined loads, particularly substantial axial loads in one direction, thanks to its defined 30° contact angle. Its compact cross-section, with a 13 mm width relative to its 80 mm bore, makes it an ideal solution for lightweight, high-rigidity systems where minimizing weight and envelope size is critical. Manufactured to ABEC-1 precision tolerances, it ensures reliable performance in high-speed and precision motion control applications.
K08013AR0 Bearing Model Code Explained, Specifications & Naming Convention
The model number K08013AR0 provides specific technical information about the bearing's dimensions and type. Below is a detailed breakdown:
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| K | Series Identifier | Denotes the Reali-Slim metric thin-section bearing series. |
| 080 | Bore Diameter | Indicates a bore diameter of 80 mm. |
| 13 | Cross-Section | Specifies the width of 13 mm, defining the slim profile. |
| A | Contact Angle | Signifies a 30° contact angle, optimized for high axial load capacity. |
| R0 | Internal Clearance | Specifies a standard radial internal clearance group. |
K08013AR0 Bearing Structural Features & Performance Benefits
The design of the K08013AR0 incorporates several key features that deliver distinct performance advantages:
- High Rigidity & Load Capacity: The single-row angular contact design, combined with a 30° contact angle and a brass cage, provides high rigidity and enables the bearing to support significant combined radial and axial loads. It offers a high axial static load rating of 4519 lbf.
- Precision & High-Speed Capability: Manufactured to ABEC-1 tolerance standards with a very low radial internal clearance, this bearing ensures smooth, precise rotation, which is essential for high-speed applications and accurate positioning.
- Space & Weight Optimization: As part of the Reali-Slim series, its thin cross-section allows for drastic reductions in weight and overall machine size without sacrificing performance, weighing only 0.28 kg.
- Durability & Temperature Resistance: Constructed from chrome steel for both rings and balls, the bearing provides excellent wear resistance and can operate within a temperature range of -30°C to 110°C.
K08013AR0 Bearing Typical Application Areas
The K08013AR0 thin-section angular contact ball bearing is ideally suited for a wide range of compact and precision-driven machinery, including:
- Robotics: Rotary joints and actuator arms where space and weight are at a premium.
- Aerospace & Defense: Guidance systems, radar platforms, and other instrumentation requiring high precision and reliability.
- Medical Equipment: Surgical robots, CT scanners, and MRI machines demanding smooth, quiet, and precise motion.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical and Imaging Systems: Rotary stages for cameras and scanning devices.
