This series of trough-shaped carrying idler groups, namely Troughing Idlers in Belt Conveyor Systems, adopts high-strength Q235B carbon steel tube for roller shells, matched with solid 45# steel shaft and pre-lubricated sealed deep-groove ball bearings. Adopting inner-outer multi-stage labyrinth double-seal construction, it achieves IP55 dust-proof and water-proof grade, stably operating within ambient temperature of -40℃ ~ 90℃. Multiple trough-angle options including 20°, 30°, 35°, 45° satisfy diversified throughput demands.
Compatible with TD75, DTII, DTII(A) mainstream belt conveyor standards, it supports belt width ranging from 500 mm-2400 mm. Surface treatments include anti-rust spray paint and rubber lagging to adapt to various harsh working conditions.
Core Product Components
Trough-shaped Welded Frame
Reinforced Q235B welded steel bracket, eliminating assembly deformation, resisting continuous vibration and impact from bulk-material conveying. Multiple inclined mounting positions reserved for different trough-angle requirements.
Roller Shell
Thick-walled high-strength carbon steel pipe, precision turning process ensures high concentricity, effectively lowers radial run-out during high-speed rotation.
Solid Steel Shaft
High-toughness 45# solid shaft, good anti-bending performance, suitable for long-term heavy-load working scenarios.
Sealed Bearing Unit
Deep-groove ball bearing pre-filled with long-service-life grease, reduces rotation resistance and delays wear progress.
Inner-outer Labyrinth Double-seal Assembly
Multi-level non-contact barrier structure, preventing mine dust, muddy slurry and fine debris from invading bearing inner cavity.
Surface Protective Layer
Anti-rust paint or rubber lagging optional; rubber-covered rollers can mitigate impact friction between sharp-edged mineral materials and conveyor belt.
Quality Control Standard
1. Raw-material incoming inspection: Steel pipe, solid shaft, bearing and sealing components are strictly inspected upon arrival; defective raw materials are rejected before entering production flow.
2. Mid-production process supervision: Monitor pipe turning, shaft finishing, bearing press-fitting, seal assembly and frame welding. Batch manufacturing records are archived for full-process traceability.
3. Bench performance testing: Random finished-product samples go through running-resistance test, axial-load durability test, water-immersion sealing test and radial-run-out measurement.
4. Appearance & dimension audit: Check welding seam quality, coating integrity, mounting-hole tolerance; screen out products with deformation, paint peeling or dimension deviation.
5. Pre-delivery final verification: Verify mill test certificates, batch inspection reports and spare-parts checklist. Complete surface cleaning before packing and container loading.

FAQ
Q: What practical factors should be weighed when selecting a trough angle for field deployment?
A: Larger trough angles bring higher conveying capacity, meanwhile users need to evaluate conveyor belt bending performance, transition-section length and actual particle size of transported bulk goods.
Q: What technical details need submitting for formal quotation of Troughing Idlers in Belt Conveyor Systems?
A: Please provide conveyor standard, belt width, target trough angle, roller diameter, surface-processing option and total order quantity for precise configuration recommendation.
Q: Is on-site modification required when replacing old idler stations with these new assemblies?
A: No extra reconstruction is required. Mounting hole spacing complies with industry-wide standard dimensions, and can be directly swapped with existing standard carrying idler stations.
