K25020AR0 Bearing Product Overview & Core Advantages
The K25020AR0 is a metric thin-section angular contact ball bearing from the Reali-Slim® series, engineered for applications demanding high precision and space optimization. This single-row bearing is designed to accommodate combined loads, efficiently handling significant radial loads and axial loads in one direction due to its defined 30° contact angle. Its compact cross-section, with a 20mm width relative to its 250mm bore, makes it an ideal solution for lightweight, high-rigidity designs in precision machinery. Manufactured to ABEC-1 tolerance standards, it ensures reliable performance and consistent operation.

K25020AR0 Bearing Structural Features & Performance Benefits
The performance of the K25020AR0 is derived from its specific construction and material selection:
- 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 6704 lbf and a substantial axial static load rating of 16331 lbf.
- Precision & Consistency: Manufactured to ABEC-1 precision tolerances, this bearing ensures smooth, low-vibration operation essential for high-accuracy applications.
- Optimized Material Selection: The use of chrome steel for both rings and balls, combined with a brass cage, provides high strength, durability, and stable operation at moderate speeds.
- Compact & Lightweight Design: As part of the Reali-Slim series, it minimizes system weight and cross-section without compromising on load capacity, enabling more compact machinery designs.
K25020AR0 Bearing Typical Application Areas
- Robotics: Rotary joints and actuator arms.
- Aerospace: Control mechanisms, gyroscopes, and radar platforms.
- Medical Equipment: CT scanners, surgical robots, and precision imaging devices.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
