1310 K Bearing Product Overview & Core Advantages
The 1310 K is a double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. Featuring a tapered bore (1:12), this metric bearing excels in handling significant combined loads, including radial and axial forces. Its open design, combined with a nylon cage and factory-applied lubrication, enables reliable performance at limiting speeds up to 8,000 rpm. This bearing is engineered for high precision and durability in demanding industrial environments.
1310 K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1310 | Standard bearing series designation indicating bearing dimensions: 50mm bore, 110mm OD, 27mm width |
| K | Tapered bore with 1:12 ratio for precise mounting on tapered shafts |
| Open | No seals or shields, optimized for high-speed applications with external lubrication |
| CN | Normal radial internal clearance for standard operating conditions |
1310 K Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides exceptional stiffness, making it ideal for applications requiring minimal deflection under heavy combined loads.
Superior Load Capacity: Engineered to handle substantial radial loads (9,810 lbf dynamic rating) while accommodating axial loads in both directions, thanks to the angular contact design.
Optimized High-Speed Performance: The nylon cage reduces friction and weight, contributing to the limiting speed of 8,000 rpm. The open design facilitates efficient lubrication and heat dissipation.
Precision Tapered Bore: The 1:12 tapered bore ensures secure mounting on tapered shafts, providing excellent concentricity and eliminating fretting corrosion.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, ensuring long service life and consistent performance within the operating temperature range of -30°C to 110°C.
