K13013AR0 Bearing Product Overview & Core Advantages
The K13013AR0 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 and ABEC-1 precision make it an ideal solution for high-rigidity, lightweight systems where accuracy and reliability are paramount.

| Code Segment | Technical Meaning |
|---|---|
| K | Indicates a specific series or design variant within the manufacturer's catalog. |
| 13013 | Specifies the core dimensions: 130mm bore, 156mm outside diameter, 13mm width. |
| A | Denotes a 30° contact angle, optimized for high axial load capacity. |
| R0 | Specifies a standard radial internal clearance group. |
K13013AR0 Bearing Structural Features & Performance Benefits
- Thin-Section Design & High Rigidity: The compact cross-section (13mm width) saves critical space and weight while the single-row, angular contact construction provides high axial and moment stiffness, ensuring precise shaft positioning.
- Superior Load Capacity: With a 30° contact angle, this bearing is engineered to support significant combined radial and axial loads. Its high axial static load rating of 6058 lbf and static load moment of 16031 lbf make it robust for demanding applications.
- Precision Performance: Manufactured to ABEC-1 tolerance class with a controlled radial internal clearance, it ensures smooth, low-vibration operation, contributing to enhanced system accuracy.
- Durable Construction: Components made from chrome steel (rings and balls) and a brass cage offer excellent durability, wear resistance, and stable operation across the specified temperature range (-30°C to 110°C).
K13013AR0 Bearing Typical Application Areas
This bearing is ideally suited for precision machinery and equipment where space and weight are constrained, including:
- Robotics (joint actuators, rotary units)
- Aerospace & Defense Systems (gimbals, control mechanisms)
- Medical Equipment (CT scanners, surgical robots)
- Semiconductor Manufacturing Equipment (wafer handling robots)
- High-Precision Rotary Tables and indexing systems
