Hot Rolled Ribbed Pulley

Advantages and characteristics:

• Light weight: the hot-rolled pulley is about 40% lighter than the cast pulley of the same specification, which makes it more efficient in applications such as lifting and transportation.
• Wear resistance: the surface of the rope groove is smooth and wear-resistant, and its hardness can be improved by heat treatment, thus extending the service life of the pulley by 1 to 2 times.
• The cutting amount is small: compared with the casting pulley, the cutting amount of the hot rolled pulley is reduced by about 70%, which not only saves materials, but also reduces the processing time and avoids the deformation problem after welding.
• Strong adaptability: Hot rolled pulley can produce different specifications of varieties, to meet the needs of single or mass production.
• Short manufacturing cycle: the production efficiency of hot rolled pulley is 10 to 20 times higher than that of cast pulley, which shortens the manufacturing cycle.
• High accuracy: the radial runout of the hot rolled pulley is 1/1000D (D is the diameter of the pulley), and the side runout is 2/1000D, which exceeds the relevant standards of West Germany and Japan.
