Description
The NTN 6315-2ZC3/2AS is a robust single-row deep groove ball bearing designed for high-load, high-speed industrial applications. With a 75mm bore, 160mm outer diameter, and 37mm width, it’s ideal for electric motors, pumps, conveyors, and gearboxes requiring durable, low-maintenance components.
This bearing features 2Z (ZZ) double-sided metal shields, offering reliable protection against dust and debris while maintaining low-friction operation. The 2AS suffix indicates enhanced sealing and lubricant retention. The C3 radial clearance allows for thermal expansion and higher speed tolerance, making it suitable for demanding environments.
Manufactured from high-carbon chrome steel and fitted with a pressed steel cage, the NTN 6315-2ZC3/2AS meets ISO Class 0 / ABEC 1 precision standards and operates reliably at speeds up to 4300 RPM (grease). With a dynamic load rating of 126.00 kN, it delivers consistent performance across a temperature range of -40°C to +120°C.
