Bulk Handling
Conveyor Rollers / Idlers (Bulk)
Carrying, impact, return and guide rollers and idler sets for bulk. Selected by tube diameter, shaft diameter, bearing type, length, load, CEMA/DIN class and trough angle.
Key parameters
Reference ranges: rollers Ø16–89 mm (unit segment) and Ø20–219 mm. Bulk idler model data is confirmed at selection.
Applications
- Quarries and processing plants
- Coal and power
- Ports and transfer
- Cement and building materials
- Overland conveyors
Selection guide
- 01Determine belt tension T1+T2 (radial load).
- 02Ensure T1+T2 is below the series' max allowable radial load.
- 03Refine diameter, power, torque and speed for the duty.
- 04Match mounting dimensions to the existing conveyor.
- 05Confirm operating conditions: IP, temperature, abrasion, Ex-protection.
A TM-Service engineer confirms the suitable execution from your data.
Construction
- Tube (steel) with calculated wall thickness
- Shaft and sealed bearing units
- Impact rings for loading zones
- CEMA/DIN class by load
- Balancing and runout by belt speed
Variants & options
- Type: carrying / impact / return / guide
- Steel / stainless / polymer / PVC
- Antistatic executions
- Garlands and idler sets by trough angle
- Seals for dust, water, abrasion

FAQ
How to match a roller to an existing idler frame?
By roller length, tube and shaft diameter, bearing type and fit, plus load and trough angle. Send dimensions or a sample.
