Basic Technical Specifications

This series of worm reducers is manufactured in accordance with the industry standard JB2318-79. The rotating speed of the input shaft shall not exceed 1500 rpm in normal operation. The high-speed input shaft supports both clockwise and counter-clockwise rotation, offering flexible installation and operation options for different application scenarios.

For the WHC120 frame size, detailed outline dimensions, mounting dimensions and drawing data are available in the full dimension table supplied by the manufacturer.

Operating Environment Requirements

The permissible ambient working temperature ranges from -40℃ to 45℃. If the site ambient temperature falls below 0℃, the lubricating oil must be preheated to above 0℃ before equipment startup to guarantee proper lubrication, avoid oil viscosity abnormality and protect internal gear and bearing components from damage during start-up.
