Description：

Cast nylon pulleys have many advantages：

① The hard steel pulley and the steel cable are rigid point contact, which makes the cable easy to wear due to the high contact pressure locally, and may even cut the cable in the initial use. The cast nylon pulley is softer and easier to slide than the steel pulley, and it has some deformation when it contacts with the cable, so it contacts with the cable as an elastic surface, thus the contact pressure decreases, the wear decreases and the service life of the cable is extended.

Steel pulleys and steel cable a contact, the cable side caused considerable deformation, so that due to the cable internal steel wire and steel wire friction between the movement, but also due to the deformation of the steel cable, the result is easy to make the cable twisted. The use of nylon rollers, as a result of the deformation of the pulley, the corresponding deformation of the steel cable is much smaller, so that the internal steel wire steel wire friction between the wear and distortion is also reduced.

(3) The nylon pulleys are not subject to rust or corrosion due to rain, moisture or chemical substances like metal pulleys, so they have a long service life and do not corrode the cable.

When steel pulleys are used in winter, ice will form due to humidity, and when ice is present, it is easy to slip and cause accidents, and the steel cable will be damaged. (4) Nylon roller has the feature of non-stick ice, so it will not cause accidents.

⑤ The nylon wheel is characterized by absorbing moisture in the air and exporting the static electricity, so there is no need to worry about sparks due to the accumulation of static electricity as in other plastic products.

In addition, nylon rollers are only 1/7 the weight of steel pulleys of the same specification, which can greatly reduce the weight of equipment, and are easy to inspect and replace. This point on a large lifting equipment on a group of pulley group has dozens of large pulley composition, weight reduction is very considerable.
