The 1310 Self-Aligning Ball Bearing features a 50 mm inner diameter, 110 mm outer diameter, and 27 mm width. Engineered with two rows of balls and a common spherical outer raceway, this bearing automatically compensates for shaft misalignment and housing deflection. Manufactured from high-grade GCr15 chrome steel or economical GCr11 carbon steel, it guarantees high precision, long-life, noise-free, and fast-speed performance. We provide customized packaging "as customer require" for B2B supply chains.
The 1310 Self-Aligning Ball Bearing is designed for applications where severe shaft bending or mounting misalignment is expected. Because the center of curvature of the outer ring raceway matches the center of the bearing, the inner ring, cage, and balls can pivot freely to align themselves. Among all rolling-element bearings, self-aligning ball bearings generate the lowest friction, making them highly suitable for high-speed continuous operations without overheating.
Ensure compatibility with your mechanical assemblies using the exact dimensions below.
Item | Specification |
|---|---|
Bearing Model | 1310 (Cylindrical bore) / 1310K (Tapered bore) |
Bore Diameter (d) | 50 mm |
Outer Diameter (D) | 110 mm |
Width (B) | 27 mm |
Material Options | Chrome Steel (GCr15/SAE52100) / Carbon Steel (GCr11) |
Cage Material | Sheet Steel (Standard) or Brass |
Dynamic Load Rating (C) | 43.4 kN |
Max Angular Misalignment | up to 3° |
Weight | ≈ 1.21 kg |
Note: The standard 1310 features a cylindrical bore. If your design requires mounting via an adapter sleeve (e.g., H310), you must specify the 1310K (tapered bore) variant during your inquiry.
The 1310 bearing delivers significant mechanical advantages for OEMs and maintenance crews:
High precision & fast speed: Strict dimensional tolerances (ABEC-1 / P0) and low-friction rolling elements allow for limiting speeds up to 6,800 r/min (with oil lubrication).
Noise-free operation: The highly polished raceways and optimized sheet steel cage ensure quiet running, even at elevated rotational speeds.
Fault tolerance: The ability to handle up to 3 degrees of angular misalignment protects machinery from damage caused by housing deformation or inaccurate shaft machining.
This bearing is indispensable in heavy-duty environments prone to vibration and structural flexing:
Agricultural and harvesting machinery.
Power transmission shafts in woodworking and spinning machines.
Heavy machinery equipment and Plummer block assemblies.
Cement industry and mining sector material handling.
We are equipped to support global distributors with flexible, high-volume production.
Material Selection: Select premium GCr15 chrome steel for maximum fatigue life or GCr11 carbon steel for cost-sensitive, light-duty applications.
Packaging: Supplied "As Customer Require." We offer bulk industrial tubes for factory floors or individually branded boxes for retail and distribution. Contact our sales team for pricing and customized logistics support.
