SF400AR0 Bearing Product Overview & Core Advantages
The SF400AR0 is a thin-section angular contact ball bearing designed for applications requiring high precision and compact design. Manufactured from stainless steel with a brass cage, this single-row bearing excels at handling combined loads, particularly significant axial loads in one direction due to its 30° contact angle. Its Reali-Slim design provides maximum load capacity within minimal cross-sections, making it ideal for space-constrained, high-reliability applications demanding corrosion resistance.
SF400AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF400 | Basic bearing designation indicating thin-section series and size |
| A | 30° contact angle for optimal axial load capacity |
| R0 | Open construction (no seals/shields) |
SF400AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: The Reali-Slim construction with 40" bore and 41.5" OD provides maximum performance in minimal space, enabling compact machinery design while maintaining high rigidity.
Superior Load Capacity: With a radial dynamic load rating of 12,147 lbf and axial static load rating of 35,580 lbf, this bearing effectively handles combined radial and axial loads. The 30° contact angle specifically optimizes axial load performance.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight radial internal clearance (0.0000-0.0005"), ensuring smooth operation and high positional accuracy.
Corrosion Resistance: Constructed entirely from stainless steel (rings and balls) with brass cage, providing excellent corrosion resistance for harsh environments and extended service life.
