Product Features
The RC series helical gearmotor is designed with compact construction and a smaller size compared to other gearmotors, allowing for the same permitted torque. Its design ensures minimal vibration and low noise, while maintaining high transmission efficiency. The gears are made of 20CrMnTi alloy steel, which undergoes heat treatment processes like tempering, cementing, and quenching to achieve a hardness of HRC58°~62°. The gears are accurately ground to a precision grade of 6~5, ensuring optimal performance.
This gearmotor has been widely used in various industries, including chemical machinery, cement agitator machinery, printing and packaging machinery, mining and power transmission machinery, and metallurgy.
