This superior troughing rollers adopts Q235B high-strength steel tube for roller shell, matched with solid alloy shaft and long-life pre-greased sealed bearings. It applies inner-outer labyrinth double-seal construction reaching IP55 dust-proof and water-proof rating, reliably operating under ambient temperature from -40℃ to 90℃. Standard trough angles include 20°, 30°, 35°, 45° to satisfy different conveying capacity requirements.
Surface treatment options cover anti-rust spray paint, black original steel finish and rubber lagging. It is fully compatible with TD75, DTII, DTII(A) and other mainstream conveyor models, supporting belt width from 500 mm-2400 mm. Cangzhou Hongpeng Conveying Machinery implements strict bench tests such as running-resistance, radial-run-out and axial-load inspection for each batch. Complete frame assemblies or separate single rollers can be supplied. Our service includes drawing evaluation, parameter matching suggestion, sample confirmation and complete export-oriented technical documentation.
Product Details
Roller Shell
Thick-walled high-strength welded steel pipe, precision turning treatment to guarantee concentricity, lower radial run-out during high-speed rotation.
Shaft & Bearing Unit
High-strength solid steel shaft cooperating with deep-groove sealed bearing pre-filled with long-term grease; effectively lower rotation resistance and extend service cycle under heavy load.
Dual-Labyrinth Sealing System
Multi-stage non-contact labyrinth barrier, effectively block mine dust, muddy water and fine debris from invading bearing cavity.
Trough-shaped Welded Frame
Reinforced Q235B steel bracket, stable welding structure, resist vibration and impact in continuous bulk-material conveying. Multiple trough-angle options available.
Surface Protection
Anti-rust painting or rubber lagging optional; rubber-coated type can reduce belt abrasion for sharp-particle material transportation.
Dimension Range
Roller diameter 89 mm-168 mm; supporting customizable roller length according to actual conveyor belt width.
Product Application
These heavy-duty trough roller assemblies serve a wide scope of bulk-material handling sectors. In coal and metal mines, they undertake heavy-load transportation of ore and raw coal on long-distance belt conveyors. For quarry and aggregate plant, they handle gravel, stone chips and granular mineral materials. In cement and chemical factories, they apply for clinker, raw-ore and chemical-granule delivery. They are also widely used at port terminals for loading-unloading bulk cargo, as well as power-plant ash-slag conveying systems.
The assemblies can be deployed for both fixed stationary belt conveyors and large-angle inclined conveying lines. According to site working-condition differences, standard steel type or rubber-lagging upgraded version can be selected. Matched self-aligning idlers, return rollers and supporting brackets are available to build a full conveyor roller system.
FAQ
Q: How to select a suitable trough angle for bulk-material conveying?
A: Larger trough angles bring higher material-holding capacity. 35° is widely used for general-purpose bulk goods; 45° is recommended for high-capacity requirements while taking belt flexibility into consideration.
Q: What key technical points should be clarified during inquiry for superior troughing rollers?
A: Please confirm conveyor model, belt width, required trough angle, roller diameter, on-site dust or corrosion condition and order quantity for precise configuration and quotation.
Q: Can you provide complete assembled roller-frame sets instead of separate loose rollers?
A: Yes. Integrated pre-welded trough idler frame assemblies are available. Finished whole-sets can be directly mounted on conveyor support beams to shorten field installation hours.
