SF140AR0 Bearing Product Overview & Core Advantages
The SF140AR0 is a high-performance thin section angular contact ball bearing designed for applications requiring exceptional precision and reliability. Engineered with a 30° contact angle, this bearing excels at handling combined radial and axial loads simultaneously. Manufactured entirely from stainless steel components with a brass cage, it offers excellent corrosion resistance and durability. Its ABEC-1 precision tolerance and optimized internal geometry ensure smooth operation and high positional accuracy in demanding systems.
SF140AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF140 | Bearing series designation for 14" bore diameter thin section bearings |
| A | Angular contact design with 30° contact angle |
| R0 | Standard radial internal clearance designation |
SF140AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: The compact cross-section (0.75" width) with 14" bore diameter provides significant space and weight savings while maintaining structural integrity.
High Load Capacity: The single row angular contact construction delivers exceptional radial dynamic load rating of 7043 lbf and axial static load capacity of 17950 lbf, making it suitable for applications experiencing significant moment loads (static load moment: 57140 lbf).
Precision Performance: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore tolerance: -0.0014" to 0") ensures consistent performance and accurate positioning.
Corrosion Resistance: Complete stainless steel construction of rings and balls provides excellent resistance to corrosion in harsh environments.
Temperature Stability: Operating temperature range of -30°C to 110°C allows for reliable performance across various environmental conditions.
