SB075AR0 Bearing Product Overview & Core Advantages
The SB075AR0 is a thin section angular contact ball bearing engineered for precision applications requiring minimal cross-section and high performance. Manufactured with stainless steel rings and balls and a brass cage, this single-row bearing is designed to handle combined radial and axial loads efficiently. Its compact design, characterized by a 7.5" bore and a slim 0.3125" width, makes it ideal for space-constrained, high-precision assemblies. The bearing is pre-lubricated and operates within a temperature range of -30°C to 110°C, offering reliable performance and corrosion resistance.
SB075AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SB075 | Indicates a thin section bearing with a 7.5-inch bore diameter. |
| A | Signifies the Angular Contact design, optimized for combined loads. |
| R0 | Specifies the Radial Internal Clearance group (0.0000 – 0.0005"). |
| Open (Seal Type) | No seals or shields, allowing for higher speeds and custom lubrication. |
SB075AR0 Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row angular contact design with a consistent 30° contact angle provides high rigidity and accurate rotational performance, suitable for ABEC-1 precision class applications.
- Superior Load Capacity: Engineered to support combined loads, with a radial dynamic load rating of 1235 lbf and a significant axial static load rating of 3120 lbf, ensuring reliable operation under complex force conditions.
- Optimized for High-Speed Operation: The brass cage ensures stability and reduced friction at high rotational speeds, while the open design facilitates efficient lubrication management.
- Corrosion Resistance and Durability: Constructed entirely from stainless steel, the bearing offers excellent resistance to corrosion and is ROHS compliant, making it suitable for harsh environments and specialized industries.
