MRVR075 Worm Drive Gearbox 20:1 Ratio Φ19mm Input Shaft with 80B5 Motor Input Flange

This MRVR075 series worm gearbox, with a gear ratio of 20 and an input shaft diameter of 19mm, is suitable for all standard IEC motors with frame 80B5.

Different from low-quality worm gearboxes on the market, STEPPERONLINE's worm gearboxes use the highest standard Tin Bronze Cu Sn12 Ni2 for the worm wheel and long-life synthetic oil (ISO VG 320) for the gearbox case. They also use high-standard bearings and oil seals. Compared with other gearboxes, the temperature rise of our gearbox is significantly reduced, while the lifespan and performance are increased by at least 30%.

This worm gearbox is widely used in mining, presses, mills, manufacturing and packaging industries, conveyors, tuning instruments, automatic gates, and many other applications.
