Optional accessories include tapered bushing kits, screw conveyor flanges, screw conveyor drive shafts, belt guards, motor mounts, backstops and more. Screw conveyors are used in a variety of applications where moving bulk material horizontally or vertically is required. Applications where screw conveyors are utilized are: aggregate and cement agriculture, grain, mining, water, wastewater and more.

The screw conveyor gearbox mounts on the trough end of a screw conveyor. Helical gearboxes offer less vibration, wear, noise and tend to have a longer life. Prior to Installation, we need to decide: how will the gearbox be mounted in order to determine the placement of the vent plug and what hardware and accessories will be required for proper mounting.

First, we inspect the gearbox for any damage that may have occurred during shipment. Clean the gearbox if needed now and during maintenance. Do not allow chemicals on the seals as they can cause seals to deteriorate and leak. Our Cast Iron Helical models include a vent plug that may be plastic like this one, or brass like this one. The vent plug is included with our Helical Gearboxes and is attached during shipping. Depending on the gearbox mounting orientation, we may need to move where the vent plug is installed.

Don't forget: we sell Worm Gearboxes, Motors, Motor controls and more.

What does a gearbox do and why would someone need one? Gearboxes, also known as enclosed gear drives or speed reducers, are mechanical drive components that can control a load at a reduced fixed ratio of the motor speed. The output torque is also increased by the same ratio, while the horsepower remains the same. 

Typical applications are used with electric motors for reducing the output speed and increasing torque. Gearboxes are used on conveyors, packaging machines, rotary tables and more! Helical Gearboxes are the most commonly used gear in transmissions. Helical gearboxes offer less vibration, wear, noise and tend to have a longer life. Helical Gearboxes are the most expensive, so the question is: what is the trade-off between the price and cost savings through efficiency and is less vibration, wear, noise and longevity important in your application?

We offer straight-through helical gearboxes with cast-iron frames. The output shaft is parallel to the input. Our gearboxes utilize C-face mounting interfaces for C-face motors. These gearboxes use helical gears to provide quiet startup and smooth operation. Worm gearboxes are more commonly used where large gear reductions are required. The design allows the worm to turn the gear, but the gear cannot turn the worm giving a braking or locking style feature.
