Conveyor Roller
托辊
Conveyor rollers are core carrying parts installed above and below the belt conveyor frame. They rotate to support the belt and conveyed material, reduce running friction and help control belt tracking.
Confirm roller diameter, length, shaft size, trough angle, seal type, belt width and working condition.

Information needed before quotation
Please send the equipment name or series, part photos, drawing or key dimensions, material condition and required quantity. This helps match the correct specification for the actual machine and working condition.
Key purchasing details to confirm
Material options
- Steel tube, polymer roller, ceramic roller or rubber impact ring, selected by dry aggregate, wet sand or loading-point duty.
Matched main machines
- WLB belt conveyor
- Aggregate belt conveyor
Required for inquiry
- Belt width
- Roller diameter, roller length and shaft diameter
- Trough angle and installation position: carrying, return, impact or self-aligning
- Seal structure requirement, such as labyrinth seal or waterproof seal
- Wet/dry working condition and quantity
Common wear causes
- Seal failure allowing mud, sand or water into the bearing
- Impact at crusher discharge or loading point
- Sticky wet sand buildup increasing belt resistance
- Thin tube deformation under long-term aggregate impact
Customization support
Yes. Diameter, length, shaft end, seal type and roller group layout can be customized.
Main components
Roller tube
Commonly made from seamless steel tube; polymer and ceramic options can also be used for specific working conditions. Wall thickness affects carrying capacity and impact resistance.
Center shaft
Solid drawn round steel runs through both ends of the roller and is fixed to the conveyor bracket.
Bearing assembly
Built-in ball bearings are the rotating core; common bearing references include 305, 306 and 204.
Sealing system
Labyrinth seal, rubber oil seal and dust cover combinations help block dust, slurry and water from entering the bearing.
End cap
Closes both ends of the roller, fixes seals and helps prevent bearing displacement.
Common specification references
Common diameters
Φ89, Φ108, Φ133, Φ159
Length matching
Matched to 600 / 800 / 1000 / 1200 mm belt width and conveyor layout
Standard sealing
Double labyrinth waterproof seal for washing and mining conditions
Quotation check

Main functions
- Carries the belt and aggregate material to prevent belt sagging and deformation.
- Uses rolling friction instead of sliding friction to reduce motor load, noise and running resistance.
- Stabilizes belt tracking and works with trough structure to reduce material spillage.
- Impact rollers at loading points reduce falling-material impact and help extend conveyor belt life.
Working-condition selection
Dry aggregate line
Standard steel rollers are usually selected for cost-effective carrying duty.
Sand washing or wet tailings line
Polymer rollers or thickened steel rollers with double sealing are preferred to reduce mud-water damage to bearings.
Crusher discharge or loading point
Impact rollers should be installed where material drops onto the belt.
Long-distance or belt-deviation site
Use upper and lower self-aligning rollers to help correct belt tracking.
Common failures
- Seal failure lets mud, sand or water enter the bearing, causing the roller to seize and damage the belt.
- Thin roller tubes can deform under long-term aggregate impact, causing eccentric running and abnormal noise.
- Wet sand buildup on the roller surface increases belt resistance; polymer non-stick rollers can be considered.
Maintenance points
- Check whether rollers rotate smoothly; replace rollers with jamming or abnormal noise in time.
- For sand washing and wet equipment, add waterproof grease every 1-3 months according to working intensity.
- Prioritize impact roller replacement at loading positions to reduce belt and roller loss.
