SG250AR0 Bearing Product Overview & Core Advantages
The SG250AR0 is a high-performance thin section angular contact ball bearing engineered for precision applications requiring exceptional rigidity and accuracy. Manufactured from stainless steel with a 30° contact angle, this bearing is specifically designed to handle combined loads, supporting significant radial and axial loads simultaneously. Its ABEC-1 precision class and inch dimensions make it an ideal component for compact, high-reliability systems where space and performance are critical.
SG250AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SG | Indicates a Stainless Steel bearing series. |
| 250 | Specifies the bore diameter of 25.0 inches. |
| A | Denotes a 30° contact angle, optimized for high axial load capacity. |
| R0 | Specifies the radial internal clearance group (0.0000 – 0.0005"). |
SG250AR0 Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its specialized construction. The single row design with a brass cage ensures stable operation and precise ball guidance. The 30° contact angle is fundamental to its ability to support high axial static loads (40,920 lbf) in combination with substantial radial loads. The stainless steel construction of both rings and balls provides excellent corrosion resistance, making it suitable for harsh environments. The thin-section design (1" width) offers a high load capacity within a minimal cross-section, saving critical space and weight (18.8 lbs) in the overall assembly. The pre-lubricated design ensures immediate operation and reduces initial maintenance requirements.
