Capable of producing 200mm-2000mm diameter iron and nylon pulley, widely used in lifting transport, port handling, ship manufacturing, grab, pulley, mining machinery, metallurgical machinery, construction and other fields, is the casting pulley, pulley replacement of twin webupdates, obvious advantages, light weight, good quality, wear, simple and beautifulappearance.

One, reasonable structure, high strength, light weight, compared with the specifications of casting pulley light 40%.

The two rope groove, smooth surface wear, and heat treatment, to increase its hardness,thereby prolonging the service life of the pulley 1-2 times.

Three, the cutting ratio of casting pulley is reduced by about 70%, thus, saving materials,reducing the processing time, and eliminates the deformation after welding.

Four, can produce varieties of different specifications, suitable for single piece or mass production.

Five, the manufacturing cycle is short (10-20 times higher than the hot rolling pulley efficiencycasting pulley).

Six, accuracy: 1/1000D radial runout (D- diameter of pulley), more than the West Germanstandards set by the DIN15063-77 5/1000D, 2/1000D more than Japanese standard lateralrunout 3/1000D.
