S77 / SA77 / SF77 / SAF77 / SAZ77 / SS77 / SAS77 / SFS77 / SAFS77 / helical gear worm gear reducer (without motor) series worm gear reducer has common characteristics, adopting the form of helical gear worm gear makes the structure more reasonable not only makes the transmission efficiency and The load capacity is higher than that of single-stage worm gear transmission, and it also reduces the space occupation in the structural layout, and at the same time, a larger transmission ratio can be obtained under similar volume conditions.It is more conducive to device configuration.The machine can be used in combination with various speed reduction and gearboxes to meet different usage requirements.

Product Description
