**Detailed Conveyor Roller / Idler Features:**
Our conveyor rollers are designed for a wide range of industrial applications including steel, mining, coal, power, cement, and more. They come in diameters ranging from 50mm to 219mm and lengths from 190mm to 3400mm. The tubes are made of Q235 steel, while the shafts are crafted from 45# steel. Bearings include single and double row deep groove ball bearings (2RZ & 2Z) with C3 clearance. The sealing system features a multi-stage labyrinth seal with a grease-retaining inner seal and an outboard rubbing flinger seal. Lubrication is done using lithium soap-based grease with rust inhibitors.
The welding process uses mixed gas shielded arc welding, and the surface finishing options include ordinary painting, hot galvanizing, electrostatic spraying, and baking. Custom manufacturing is available based on customer requirements.
