Application & Selection

Where the WPA 050 Is Installed in Australia

Entry-level standard industrial gearbox for small packaging machines, ventilation fan drives, automated gate operators, and light-duty screw conveyors in grain handling. The 50 mm centre distance marks the transition from micro to standard industrial applications. Popular in regional Victorian food production where cast-iron durability outweighs the weight savings of aluminium.

When to Choose This Model

The WPA 050 covers the below 0.80 kW. Step to WPA 060 for 1 kW+ motors. Choose cast iron over aluminium when the application involves sustained vibration, belt-tension side loads, outdoor installation, or ambient temperatures above 45 degrees C.

For materials, configuration variants, efficiency data, lubrication, and selection methodology, refer to the WPA/WPS Series overview.
