Worm reducers 2CH-40 … 2CH-80

Single-stage worm reducers 2CH (2CH-40, 2CH-63, 2CH-80) are a universal general-purpose mechanism. Specialists use them to change torque and speed.

The worm reducers 2CH is used in the following conditions:

• constant and variable, unidirectional and reversible load;
• work began with periodic stops;
• rotation of shafts in any direction without advantage with the frequency of rotation of the input shaft up to 1500 rpm;
• ambient temperature from -40 °C to +50 °C;
• humidity up to 95% at a temperature of +20°C;
• height above sea level – no more than 1000 m.
