Idler

The idlers are designed and manufactured with proprietary technology and special equipment. The bearing seat and dust cover are stamped from high-quality steel plates. The idler body is made of high-frequency seam welded pipe with uniform wall thickness, high roundness and straightness. The stamped bearing seat and the idler roller body are welded by automatic carbon dioxide gas shielded welding. Bearings are special large clearance bearings for idlers. It adopts a 4-way combined sealing structure with good sealing performance, which has good waterproof and dustproof performance, and is especially suitable for dusty and rainy working environments. The roller bearings are lubricated with disposable long-lasting lithium-based grease. The service life of the idler under normal working conditions is not less than 30,000 hours, and the damage rate during the service life is not more than 10%. It has the characteristics of light weight, stable operation, flexibility, small resistance, low energy consumption, low noise and long service life. Its structure is shown in the figure below:

The rotational frictional resistance coefficient of the idler under laboratory conditions is 0.02~0.022.

The idler is produced by a production line composed of efficient special equipment, which realizes specialized production, including the production line of idler shaft, pipe body, sealing cover, bearing seat, idler assembly and so on.
