K02508AR0 Bearing Product Overview & Core Advantages
The K02508AR0 is a metric thin-section angular contact ball bearing engineered for applications demanding high precision and space-saving design. As part of the Reali-Slim mm Metric Bearings series, it features a single row construction optimized to handle significant combined loads, including substantial thrust loads in one direction due to its 30° contact angle. Its compact cross-section, with an 8 mm width, makes it ideal for high-accuracy and high-reliability systems where minimizing envelope size is critical.
K02508AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K02508 | Indicates the specific thin-section bearing size series (25mm bore, 41mm OD, 8mm width). |
| A | Denotes a 30° contact angle, optimized for handling high axial loads. |
| R0 | Specifies a standard radial internal clearance and open (unsealed) construction. |
K02508AR0 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to ABEC-1 tolerance standards with a brass cage for stable operation and precise rotational accuracy, providing high system rigidity despite the thin cross-section.
- Superior Load Capacity: The 30° contact angle and robust chrome steel construction enable the bearing to support high combined radial and axial static loads (1237 lbf axial static load rating).
- Optimized for Compact Designs: The thin-section bearing design provides a large bore diameter relative to its cross-section, maximizing space utilization in lightweight assemblies.
- Wide Operating Range: Pre-lubricated and capable of operating within a temperature range of -30°C to 110°C, ensuring performance across various environments.
