SG350AR0 Bearing Product Overview & Core Advantages
The SG350AR0 is a thin-section angular contact ball bearing engineered for applications requiring high precision and space optimization. This stainless steel bearing features a single-row design with a 30° contact angle, enabling it to efficiently handle combined loads—significant radial loads alongside substantial thrust loads in one direction. Its ABEC-1 precision and Reali-Slim cross-section make it ideal for compact, high-rigidity assemblies where weight and space are critical constraints. The bearing comes pre-lubricated for immediate operation across a wide temperature range.
SG350AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SG | Indicates the bearing series (Reali-Slim thin-section type) |
| 350 | Specifies the nominal bore diameter in inches (3.500") |
| A | Denotes angular contact geometry |
| R0 | Specifies the radial internal clearance group |
SG350AR0 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides optimized support for combined radial and axial loads. With a radial dynamic load rating of 17,982 lbf and axial static load rating of 50,840 lbf, it delivers reliable performance in demanding applications.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore/OD tolerance: -0.0020" to 0"), ensuring smooth operation and accurate positioning.
Corrosion Resistance & Durability: Constructed entirely from stainless steel (rings and balls) with a brass cage, offering excellent corrosion resistance and longevity in harsh environments.
Space-Saving Design: The Reali-Slim thin-section construction (1" width) minimizes weight and envelope size while maintaining high performance, with a total weight of just 26.2 lbs.
