Description
The NTN 6310LLUC3/2AS is a heavy-duty single-row deep groove ball bearing engineered for high-load, high-speed applications. With a 50mm bore, 110mm outer diameter, and 27mm width, it’s ideal for electric motors, conveyors, gearboxes, and industrial pumps.
This bearing features LLU double-sided contact seals made from nitrile rubber, offering superior protection against dust, moisture, and contaminants. The 2AS suffix indicates enhanced sealing and lubrication retention, while the C3 radial clearance allows for thermal expansion and higher speed tolerance.
Made from high-carbon chrome steel and fitted with a pressed steel cage, the NTN 6310LLUC3/2AS meets ISO Class 0 /ABEC 1 precision standards and operates reliably at speeds up to 4200 RPM. With a dynamic load rating of 68.5 kN, it delivers consistent performance across a temperature range of -40°C to +120°C.
