Customize Coal Industry High Quality Conveyor Roller

AstraRoll High-Quality Conveyor Roller (89-1100 mm)

Manufactured with high-grade Q235 seamless carbon-steel tube as roller shell, paired with precision-machined solid steel shaft. The standard outer diameter is 89 mm, and effective working length can be customised from 110 mm up to 1100 mm to match various conveyor frame widthses.Made-in.... Every roller assembly adopts premium deep-groove ball bearings (6205 / 6305 series) with C3 internal clearance and permanent high-performance lithium-based grease filling, delivering low starting torque, quiet running and reduced energy consumption for your whole conveyor line.

One of the core technical highlights of the AstraRoll conveyor roller is its multi-stage labyrinth combined sealing structure. Internal and external labyrinth seals plus dust-proof end caps block dust, mud splash and humid water vapour from penetrating into bearing chambers. This greatly extends service life under harsh outdoor, dusty or wet site conditions and lowers unplanned equipment downtime and maintenance workload.

Each roller undergoes strict quality-control procedures: tube straightening, shaft precision machining, automatic double-end welding assembly, dynamic-rotation testing and air-tightness inspection before packing. The roller surface can be supplied with spray-paint, powder-coating or hot-dip galvanised anti-corrosion finishes according to customer working-environment requirements. Both spring-loaded quick-release shafts and fixed-type solid shafts are available for different installation-and-maintenance scenariosHebei Binx.
