What is the difference between drive and tail pulleys?
The drive pulley is powered by the motor and pulls the belt; the tail pulley is an unpowered redirect at the loading end, often with a take-up.

Usage
Usage
Drive Pulley — the powered pulley that the motor turns to pull the belt. Usually lagged for grip, it converts motor torque into belt tension and speed; its diameter and lagging decide how much load the conveyor can move without slip.
Operating conditions
Operating conditions
| Working temperature | Ambient range (-20 °C to +40 °C); rubber or ceramic lagging rated about -20 °C to +80 °C. |
|---|---|
| Dusty environment | Suitable — labyrinth or IP65 seals keep dust out of the bearings |
| Moisture & water | Suitable — IP65 sealing for outdoor, port, washdown and humid duty |
| Corrosive environment | Powder-coated for ordinary acid or alkali · Galvanized for coastal and semi-outdoor · Stainless for high-salinity and high-humidity sites |
| Certification | MA coal-mine safety certified versions available — confirm the certified SKUs for your project |
| Outdoor use | Suitable — coated and stainless options for coastal and weathering service |
Technical overview
Pulleys drive, redirect and tension the conveyor belt across the system. HBXM pulleys are available from 200 mm to 1600 mm diameter with static or vulcanized rubber lagging, and are dynamically balanced for smooth running at high belt speeds.
Why add rubber lagging to a pulley?
Lagging increases friction so the belt does not slip, protects the shell from wear, and can be grooved to shed water and mud.
What is a motorized pulley?
A motorized pulley encloses the motor and gearbox inside the drum, giving a compact, sealed, low-maintenance drive for confined spaces.
How do I size a conveyor pulley?
Size by shaft and bearing load from belt tension and torque, then choose diameter for the target belt speed and lagging type.
What is a conveyor belt drive pulley?
A conveyor belt drive pulley is the powered drum that transmits motor torque to the belt through friction. HBXM drive pulleys use vulcanized rubber or ceramic lagging to grip the belt without slip.

FAQ
Frequently asked questions
How do I size a drive pulley?
From the belt tension and the wrap angle: the pulley diameter must give enough traction for the drive torque without exceeding the belt's minimum pulley diameter. Send us the tensions and we will confirm the diameter.
Do you supply the shaft and bearing assembly?
Yes — shaft, bearing housings, locking assemblies and lagging are all made in-house, so the assembly arrives matched and ready to mount.
What lagging do you fit as standard?
Plain rubber, grooved rubber or ceramic depending on duty. For wet or muddy drives we recommend ceramic as standard.
