What is the difference between carrying and return idlers?
Carrying idlers support the loaded top strand of the belt; return idlers support the empty bottom strand on its way back to the tail.

Usage
Usage
Nylon Idler — an idler with a nylon shell: light, corrosion-free, low-noise and anti-static. For chemical, food, underground (low-spark, flame-retardant) and quiet plant duty it replaces steel where rust or spark risk is unacceptable.
Operating conditions
Operating conditions
| Working temperature | Ambient service range (-20 °C to +40 °C); sealed bearings and PU or ceramic parts tolerate wider material temperatures. |
|---|---|
| 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
Idlers are the rotating rollers that support the conveyor belt and the bulk load traveling on it. HBXM idlers cover belt widths up to 2400 mm and trough angles of 20 deg, 35 deg or 45 deg, with multi-labyrinth sealed bearings built for continuous duty in dust, moisture and fine powder.
Why use a self-aligning idler?
A self-aligning idler automatically corrects belt mistracking, reducing edge wear, spillage and unplanned downtime.
What bearing seals does HBXM use?
We use non-contact multi-labyrinth seals that keep grease in and keep dust, water and fine powder out for a long service life.
Can idlers handle high-capacity mining lines?
Yes. Our heavy-duty series is specified for mines, ports and power plants with high belt speeds, large lump sizes and continuous operation.
What are conveyor rollers?
Conveyor rollers, also called idlers, are the rotating cylinders that carry the belt and the material on it. HBXM makes them in steel, UHMW-PE, nylon and polyurethane to suit different loads, belt speeds and environments.
How much do conveyor rollers cost?
Roller price depends on diameter, length, material (steel, UHMW-PE, polyurethane) and order quantity. Send your conveyor specs — belt width, load and environment — and we will quote an exact price and lead time.
What is a polyurethane conveyor roller used for?
Polyurethane rollers resist abrasion, oils and impact better than steel and run quieter, so they suit wet, sticky or abrasive material and applications where belt marking matters.
