SF300AR0 Bearing Product Overview & Core Advantages
The SF300AR0 is a high-performance thin section angular contact ball bearing engineered for precision applications requiring exceptional rigidity and load capacity. Constructed entirely from stainless steel with a brass cage, it is designed to handle significant combined loads—simultaneously supporting substantial radial and axial forces. Its 30° contact angle optimizes it for high axial load capacity, while the compact, thin-section design (0.75" width) allows for space-saving integration in sophisticated machinery. This bearing is pre-lubricated and operates reliably within a temperature range of -30°C to 110°C, making it a robust and durable solution for demanding environments.
SF300AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF300 | Indicates the bearing series and cross-section size (Reali-Slim). |
| A | Signifies a 30° contact angle, optimized for high axial load capacity. |
| R0 | Specifies the radial internal clearance group. |
| Open (Seal Type) | No seals or shields, allowing for higher speeds and custom lubrication schemes. |
SF300AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design, combined with a 30° contact angle and a robust brass cage, provides high rigidity. This enables the bearing to support a radial dynamic load rating of 10,533 lbf and a significant axial static load rating of 29,430 lbf.
- Precision Performance: Manufactured to ABEC-1 tolerance class with tight bore and outside diameter tolerances, ensuring smooth, precise operation and reliable performance in high-accuracy systems.
- Corrosion Resistance & Durability: The use of stainless steel for both rings and balls provides excellent corrosion resistance, making it suitable for harsh environments and extending service life.
- Optimized for Combined Loads: The inherent design of angular contact ball bearings makes the SF300AR0 ideal for applications where radial and axial loads are present simultaneously.
