(Save $0.96)Description
The NTN 6309LLUC3/2AS is a premium-grade single-row deep groove ball bearing built for durability, precision, and smooth operation under demanding conditions. With a 45mm inner diameter, 100mm outer diameter, and 25mm width, it’s ideal for medium to heavy-duty applications including electric motors, gearboxes, pumps, and conveyors.
This bearing features LLU double-sided contact seals made from nitrile rubber, providing excellent protection against dust, moisture, and contaminants. The 2AS suffix indicates enhanced sealing performance with Shell Alvania #2 grease pre-filled for long-lasting lubrication. The C3 radial clearance allows for thermal expansion and higher speed tolerance, making it suitable for high-speed and high-load environments.
Constructed from high-carbon chrome steel and fitted with a pressed steel cage, the NTN 6309LLUC3/2AS meets ISO Class 0 / ABEC 1 precision standards and operates reliably at speeds up to 4700 RPM. With a dynamic load rating of 58.5 kN, it delivers consistent performance and extended service life across a temperature range of -40°C to +120°C.
