1315K Bearing Product Overview & Core Advantages
The 1315K metric bearing is a double row angular contact ball bearing engineered for demanding industrial applications requiring high precision and reliability. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing excels at handling significant radial loads while offering excellent operational stability. Its double row construction provides enhanced rigidity and load distribution, making it ideal for machinery where high stiffness is critical. Manufactured from premium chrome steel with a stainless steel cage, it delivers consistent performance across a wide temperature range from -30°C to 110°C.

1315K Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row angular contact configuration provides superior stiffness compared to single row bearings, effectively minimizing deflection under heavy radial loads and ensuring precise shaft positioning.
Optimized Load Capacity: Engineered to handle substantial radial dynamic loads up to 17,842 lbf, this bearing maintains stable operation in demanding conditions. The CN radial clearance offers balanced performance for most industrial applications.
Precision Engineering: Manufactured with tight dimensional tolerances (bore: -0.015mm to 0, OD: -0.025mm to 0) and featuring precisely calculated shoulder diameters (inner: 104.8mm, outer: 135.2mm) for optimal mounting and load distribution.
Enhanced Durability: The combination of chrome steel rings and balls with a stainless steel cage provides excellent corrosion resistance and mechanical strength, supporting a limiting speed of 5,600 rpm.
