Rated voltage: DC12V; No-load speed: 8RPM; Rated speed: 6.5RPM; Rated torque: 48kg.cm; the output shaft can't rotation when power-off, that is the Turbo worm geared motor with self-lock; Package: 1Pcs x DC Worm Gear Motor;. DC Motor Body Dimensions: 31 x 57mm/ 1.22" x 2.24"(D*L); Gear Box Dimensions: 58.1 x 40.1 x 35mm/ 2.28"x1.57"x1.37"(L*W*H), Output Shaft Dimensions: 8 x 15mm/ 0.31" x 0.59"(D*L) with 1x 13mm/ 0.039*0.51(H*L) flat cut off; Wire Length: 19mm/7.4";. You can change the wiring-connection to change shaft rotation direction, the reducer output shaft arranged vertically with the motor shaft, whole motor output is relatively short,can be widely used in various of occasions that require special installation size;. Double ball bearings effectively reduce friction between bearing surfaces, improve mechanical power transmission efficiency and lifespan; Using metal materials with good impact resistance, durability, and ultra-low noise to create a durable and long-lasting gearbox;. How to choose the torque: if driven by a pulley, the radius of the pulley is 1cm, the pulling force of the belt is 25kg; if the radius of the pulley is 2cm; the pulling force of the belt is 12.5kg, and so on; and transmission efficiency and grinding coefficient must be considered in combination with the actual situation;.
