Description

The NTN 6305LLUC3/2AS is a high-performance single-row deep groove ball bearing designed for durability, precision, and quiet operation. With a 25mm bore, 62mm outer diameter, and 17mm width, it’s ideal for electric motors, pumps, gearboxes, and other industrial applications requiring compact yet powerful components.

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 6305LLUC3/2AS meets ISO Class 0 / ABEC 1 precision standards and operates reliably at speeds up to 8100 RPM. With a dynamic load rating of 23.5 kN, it delivers consistent performance across a temperature range of -40°C to +120°C.
