Conveyor Gearbox Types and Selection
Conveyor gearboxes match motor speed and torque to the conveyor duty. They are usually reviewed together with the drive arrangement and related belt conveyor parts when a buyer is planning a new line or replacing an existing reducer.
This page reviews common gearbox choices for belt conveyors, chain conveyors, roller conveyors and pallet conveyors, plus the project details that help speed up technical review and quotation.
How to Choose a Conveyor Gearbox
A conveyor gearbox transfers motor power to the drive arrangement and helps the line reach the speed and torque required by the application. Buyers usually review the gearbox together with the wider belt conveyor parts package, especially when a drive is being replaced or a new line is being specified.
How to choose a conveyor gearbox
- Start with the conveyor type: belt conveyor, chain conveyor, roller conveyor or pallet conveyor
- Confirm the required output speed, operating load, duty cycle and whether the conveyor starts under load
- Check the available mounting direction, shaft arrangement and installation space around the drive section
- Review the environment, such as food processing, logistics, mining or washdown conditions
- Decide whether the project needs a new gearbox package or a replacement that must match an existing motor and drive layout
What buyers should share for quotation
For a faster review, send the conveyor layout, conveyor type, required speed, approximate load, motor data if available and any replacement gearbox nameplate or mounting details. If the drive train also includes related components, it helps to note nearby parts such as bearings, sprockets or pulleys.
FAQ
Can one gearbox type fit every conveyor?
No. The right reducer depends on the conveyor duty, drive arrangement, available space and torque requirement. That is why the same factory may use different gearbox types across belt, roller, chain and pallet lines.
What usually causes gearbox under-sizing?
Missing load, startup or duty-cycle information is a common issue. When a gearbox is selected only by conveyor speed and not by the full working condition, service life and reliability can suffer.
Do replacement orders need the old gearbox details?
Yes. Sharing the old model, shaft size, ratio, mounting position and motor information reduces mismatch risk and speeds up quotation.

Belt conveyor system
Belt conveyors are used to conveying items and packages in horizontal, inclined or turning directions. Belt conveyors include heavy-duty conveyors and light-duty conveyors. Parallel shaft helical gearboxes, helical-bevel gearboxes, and helical turbo gearboxes are widely used in light load belt conveyors. These gearboxes are generally used in the logistics industry, sorting centers, express e-commerce, food industry, medical industry, etc.
For heavy-duty belt conveyors generally use cylindrical gear reducers with 2, 3, 4 reduction stages, etc. Cylindrical gear reducers are generally used in mining, coal mining, quarrying plants, ports, grain, cement, construction, and other industries.
Chain conveyor system
A chain conveyor is used to convey materials with a chain as traction and carrier. Chain conveyor has a large conveying capacity, mainly conveying pallets, line boards, material boxes, large crates, etc. Parallel shaft helical gear reducers, parallel shaft helical gearboxes, spiral bevel gear reducers,s and coaxial helical hardened gear reducers are most widely used in chain conveyor systems.
Roller conveyor system
A Roller conveyor is conveying equipment that uses a number of rollers mounted on a frame to move objects. According to the shape, load and working condition of the conveyed objects, roller conveyors are divided into common roller conveyors and heavy-duty roller conveyors. Individual roller conveyors generally have a short conveying distance and compact installation space, so they use parallel shaft helical gearboxes, worm gearboxes, and helical-bevel gearboxes of small size. When the roller conveyor needs to convey heavier weight and larger volume items, you need to choose to use a reducer model with higher power and torque.
Pallet conveyor system
The pallet conveyor system takes the pallet as the load-bearing unit, and the conveying equipment includes: chain conveyor, roller conveyor, transfer conveyor, pallet elevator, palletizer and depalletizer, etc. Because the system is composed of a variety of devices, there are various types of gearboxes. Helical gearbox, worm gearbox, planetary gearbox, helical-turbine gearbox，cycloid gear reducer, etc. are very widely used in pallet conveying systems.
Reliable conveyor performance depends on choosing a reducer that matches the working condition and then maintaining it correctly. Replacement work moves faster when buyers can share the old gearbox model, speed ratio, shaft arrangement, mounting direction and the motor data already installed on the conveyor.
Common Conveyor Gearbox Types
The following gallery shows common reducer forms used in conveyor systems. Horizontal or vertical mounting can be chosen according to the drive arrangement, available space and duty of the line.
