Product Features
1. RC series helical gear motor owns the rational design, compact construction, and smaller size than X or B series cycloidal gearmotor under the condition of the same permitted torque.
2. Little vibration and low noise, with high transmission efficiency.
3.The material of gears is 20CrMnTi alloy steel and the hardness can reach to HRC58°~ 62° after tempering, cementiting,quenching etc. heat treatment. All the gears are processed by accurate grinding and the precision can reach to grade 6~5.
4. The products have been mainly used in chemical machinery, cement agitator machinery, printing and packaging machinery, mine and power transmission machinery, metallurgy, etc.
