K02513AR0 Bearing Product Overview & Core Advantages
The K02513AR0 is a single row angular contact ball bearing from the Reali-Slim mm Metric Bearings series, designed for applications demanding compact cross-sections and high precision. This bearing is engineered to support combined loads, handling significant radial and axial loads simultaneously due to its specified 30° contact angle. Manufactured to ABEC-1 tolerance standards, it ensures reliable performance in high-accuracy and high-reliability scenarios where space and weight are critical constraints.
K02513AR0 Bearing Model Code Explained, Specifications & Naming Convention
The model number K02513AR0 can be broken down to understand its technical specifications:
- K: Indicates a metric Reali-Slim series bearing.
- 02: Specifies the cross-section series (light).
- 5: Indicates a 25 mm bore diameter.
- 13: Indicates a 13 mm width.
- A: Denotes a 30° contact angle.
- R: Specifies a brass (machined) cage.
- 0: Indicates a standard radial internal clearance.
K02513AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 30° contact angle is optimized to support substantial combined radial and axial loads. The robust chrome steel construction of rings and balls ensures high durability and load ratings.
- Precision Performance: Manufactured to ABEC-1 precision tolerances with a very tight radial internal clearance (0.0000 – 0.0005"), ensuring smooth, precise operation essential for high-accuracy applications.
- Cage Design: The brass cage provides excellent guidance and stability for the balls, contributing to smooth operation at moderate speeds and reliable performance.
- Compact & Lightweight: As part of the Reali-Slim series, this bearing features a thin cross-section, saving space and reducing overall weight (0.13 kg), which is critical in compact machinery designs.
K02513AR0 Bearing Typical Application Areas
The K02513AR0 is ideally suited for a variety of compact and precision machinery, including:
- Robotics (joint and actuator bearings)
- Aerospace control mechanisms and instrumentation
- Medical Equipment (scanners, small precision drives)
- Semiconductor Manufacturing Equipment
- Optical Positioning Systems
