Selecting the right gearbox is crucial for ensuring the efficiency, reliability, and longevity of a conveyor system. Different conveyor layouts—horizontal, inclined, modular, or heavy-duty—demand specific gearbox types based on load, torque, orientation, and duty cycle. This guide simplifies gearbox options and where they work best.

Common Conveyor Gearbox Types & Applications
Gearbox TypeFeaturesBest-Fit Applications
Helical GearboxHigh efficiency, inline shaft, smooth torqueLong belt conveyors, production lines, packaging
Bevel Helical GearboxRight-angle with helical-bevel combinationInclined conveyors, bucket elevators, aggregate handling
Worm GearboxCompact, right-angle drive, self-lockingIndexing conveyors, food-grade systems, compact setups
Planetary GearboxHigh torque density, compact multi-stageMining, steel processing, heavy bulk conveyors
Cycloidal GearboxShock-resistant, high reduction in small sizeVibratory feeders, load-variable conveyors
Parallel Shaft HelicalHigh-load inline gearbox with parallel shaftsCement plants, airport baggage conveyors, heavy-duty runs
Inline Helical-Bevel GearmotorIntegrated motor-gearbox unit, space-savingOEM modular conveyors, robotics, and packaging systems
Matching Gearbox Types with Conveyor Applications
Conveyor TypeRecommended GearboxWhy?
Long Distance Belt ConveyorHelical or Parallel Shaft HelicalOffers durability and high transmission efficiency
Inclined or Vertical ConveyorBevel Helical or WormDelivers optimal torque at angles
Mining/Heavy-Duty SystemsPlanetary or Bevel HelicalDesigned for high loads and impact conditions
Bucket ElevatorsWorm or Bevel HelicalSuits vertical load-bearing applications
Light Roller ConveyorsInline Helical or WormCompact, efficient for intermittent use
Modular Plastic BeltInline Helical-Bevel GearmotorSleek integration for automation environments
Food-Grade SystemsIP-rated Stainless Worm or HelicalEnsures hygiene, washdown-compatible
Key Gearbox Selection Criteria
  • Load Nature: Continuous, fluctuating, or shock loads
  • Required Torque: Based on conveyor length, material weight, and angle
  • Output Speed (RPM): Needed for belt speed targets
  • Mounting Orientation: Shaft-mounted, foot, or flange
  • Space Limitations: Inline or right-angle configurations
  • Duty Cycle: Continuous or intermittent operations
  • Environmental Exposure: Dusty, corrosive, high-temp, or washdown zones

Pro Tip: For high-shock environments like crushers or vibratory feeders, cycloidal gearboxes outperform others in longevity.
