Worm gearboxes and worm geared motors
JS-Technik GmbH specialises in extensive challenges in the field of professional drive technology with a focus on electric motors, frequency inverters and geared motors. Test our worm gearboxes and be surprised and convinced by the short delivery time and high quality.
Drive combinations
The worm gearboxes are available in various speeds, i.e. from 2 to 600 rpm (revolutions per minute). In many cases, worm gearboxes - electric motors - combinations with customised requirements are needed. We are the ideal partner for you here, because with decades of experience and our own final assembly, we can cover a wide range: worm gearboxes with brake motors, special shafts, grill motors with gearboxes, as worm gearbox motors with forced cooling fans, special voltage or in explosion-proof design.

Size and performance of worm geared motors
In our online shop, you will find a selection of worm geared motors with various revolutions per minute (rpm, rpm, rpm or 1/min). The worm geared motors are made from an aluminium or grey cast iron housing and are available in sizes NMRV, 30, 40, 50, 63, 75, 80, 90, 100, 110, 125, 130 and 150. The gearboxes are available with an output of 0.09kW, 0.12kW, 0.25kW, 0.37kW, 0.55kW, 0.75kW, 1.1kW, 1.5kW, 2.2kW, 3.0kW, 4.0kW, 5.5kW, 7.5kW and 11kW.
Shaft diameters and torques
The aluminium worm gearboxes are available with the following hollow shafts: 14 mm, 18 mm, 20 mm, 25 mm, 28 mm, 30 mm, 35 mm, 40 mm, 45 mm and 50 mm. The torque output depends on the motor power, the efficiency and the output speed. Taking these points into account, we supply worm gearboxes in a range of 10 - 2000 Nm.

Angular gearbox function
Worm gearboxes, also known as angular gearboxes, consist of a shaft with one or more helical gears, the worm and a meshing helical gear, the worm wheel. The axes of the two are offset by 90°. Special areas of application for such a gearbox are where high reduction ratios are required in one step. There are left-hand and right-hand worm geared motors. Both directions of rotation are equally possible. The complete flexibility of the mounting options includes foot, flange and centring solutions with a torque arm. Self-locking is available from an efficiency of less than 50 %.
Worm gearbox - mounting
The motor terminal box can be mounted in 90° steps around the motor. The JS geared motor can be installed in almost any required position. The installation positions are labelled M1, M2, M3, M4, M5, M6.
