Many overseas purchasers mention troubles brought by thin-wall standard rollers. Thin tube shells corrode quickly in damp coastal or mineral-rich sites, internal bearings jam frequently, creating loud running noise and needing frequent replacement. To solve such problems, our heavy-duty idlers adopt 4.0mm seamless steel tube as the shell, matched with double labyrinth sealing structure to reach IP65 waterproof and dustproof grade.
Each matched bearing will complete 500 hours continuous operation test before assembly, keeping rotation resistance below 3N. Under the same operation conditions, the service cycle can be greatly extended, and daily maintenance workload will drop obviously.
We supply a full range of rollers to match different conveying demands. Conventional carrying idlers apply to normal bulk material transportation. Thickened impact idlers are designed for feeding positions with falling lump materials, effectively buffer impact force and avoid tube deformation. Return idlers, rubber disc return rollers and self-aligning training idlers are all available to solve belt deviation and material accumulation on return sections.
Custom options are prepared for special operation environments. High temperature resistant idlers can work stably under 150°C high temperature from cement clinker. Plastic anti-corrosion rollers fit chemical workshops and coastal areas, with strong anti-rust and anti-aging performance.
Strict inspection will be carried out for every roller before delivery. Our workers test tube wall thickness, shaft concentricity and bearing flexibility one by one. Complete inspection documents will be attached to each container, supporting customs clearance and buyer's internal quality acceptance smoothly.
Small batch trial supply is acceptable for clients to verify on-site performance, mass full-container supply is also supported for large-scale projects. Our technical staff will not recommend over-standard high-cost products without basis. According to your belt width, conveying capacity and site environment, we will select the most matched roller specification to control your procurement expenditure reasonably.
Our conveyor idler rollers have stable supply to Southeast Asia, Middle East and African mining regions all year round. Most cooperative clients feedback our rollers run smoothly with low failure rate compared with ordinary market products.
If you are plagued by frequent roller jamming, rust and short service life, you can contact us anytime. We can provide detailed parameter matching, sample supply and factory direct quotation for your reference.
