1320 Bearing Product Overview & Core Advantages
The 1320 is a metric double row angular contact ball bearing engineered for demanding industrial applications requiring high precision and reliability. This precision bearing is designed to accommodate significant combined loads, simultaneously supporting substantial radial forces and moderate axial loads in both directions. Its double row construction provides exceptional high rigidity and stability, making it an ideal solution for applications where shaft deflection must be minimized. With its open design and high-grade materials, the 1320 offers excellent performance in high-speed operations.
1320 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1320 | Basic bearing designation indicating the bearing size (100mm bore × 215mm OD × 47mm width) |
| Open | No seals or shields, allowing for optimal lubrication access and heat dissipation |
| Double Row | Two rows of balls providing enhanced load capacity and rigidity |
1320 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design significantly increases radial and axial stiffness, enabling the bearing to handle combined loads of up to 32,175 lbf dynamic and 12,825 lbf static ratings. This construction provides superior resistance to moment loads and shaft deflection.
Optimized for High-Speed Operation: Featuring a stainless steel cage that ensures reliable performance at limiting speeds up to 4,000 rpm. The open design facilitates efficient lubrication flow and heat dissipation, critical for maintaining performance in high-speed bearing applications.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, providing excellent wear resistance and durability. The stainless steel cage offers corrosion resistance and maintains dimensional stability across the operating temperature range of -30°C to 110°C.
Precision Engineering: Tight dimensional tolerances on bore diameter (-0.02mm to 0) and outside diameter (-0.03mm to 0) ensure precise fit and optimal performance in precision machinery applications.
