SG300AR0 Bearing Product Overview & Core Advantages
The SG300AR0 is a precision thin-section angular contact ball bearing engineered for applications demanding high rigidity and accurate motion control. Manufactured with a single-row design from corrosion-resistant stainless steel, this bearing excels in handling combined loads (simultaneous radial and axial forces) due to its specified 30° contact angle. Its ABEC-1 precision class and inch-system dimensions make it ideal for compact, weight-sensitive assemblies requiring reliable performance.
SG300AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SG | Indicates Reali-Slim thin-section bearing series |
| 300 | Specifies cross-section size and series designation |
| A | Denotes 30° contact angle for optimal axial load capacity |
| R0 | Specifies standard radial internal clearance (0.0000 – 0.0005") |
SG300AR0 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single-row angular contact design with 30° contact angle provides exceptional stiffness and can support combined radial and axial loads simultaneously. With a radial dynamic load rating of 16,687 lbf and axial static load capacity of 46,020 lbf, it delivers reliable performance in demanding applications.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional controls (bore diameter tolerance: -0.0018" to 0"), ensuring smooth operation and accurate positioning. The brass cage provides stable ball guidance and reduced friction.
Corrosion Resistance & Durability: Constructed entirely from stainless steel (rings and balls), offering excellent corrosion resistance for harsh environments. The open design allows for custom lubrication schemes optimized for specific operating conditions within the temperature range of -30°C to 110°C.
