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
Oil-Cooled Motorized Pulley — a pulley with the motor and gears sealed inside the drum, oil-cooled. It removes the external motor, coupling and gearbox, so the drive sits inside the belt line: compact, sealed and ideal for wet, dusty or confined spaces.
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
What are the advantages of a motorized pulley?
Sealing. Everything is inside an oil-filled drum, so dust, water and washdown do not reach the motor or gears. That usually means several times the service interval of an external drive.
What is the power range?
Standard ranges run from around 0.55 kW to 45 kW; above that an external drive is usually more economical. Send us belt speed and required torque and we will size it.
How is it cooled?
Oil-cooled designs use the oil to carry heat to the shell, which the moving belt then cools. Grooved or finned shells help in slow-running or high-torque duties.
