What types of shower room pulleys are there?

Many shower room manufacturers will wear nylon coats in the production of shower room pulleys, because there are bearings inside, and the bearings play a decisive factor in the service life of the pulleys. At present, there are more copper, carbon steel, zinc alloy and stainless steel bearings on the market. Among them, 304 stainless steel pulleys should be used as much as possible, and copper materials should be selected next. As for alloy materials, they are inferior materials to carbon steel, and their service life is low. It affects whether the daily use of the overall shower room is smooth and the service life.

What are the characteristics of shower room pulleys made of different materials? Let's find out together.
1. Zinc alloy pulley: a pulley made of an alloy material composed of zinc as the base material and other elements. Zinc alloy has low melting point, good fluidity, easy fusion welding, brazing and plastic processing, and the residual waste is easy to recycle and remelt; but the creep strength is low, the corrosion resistance is poor, and it is prone to dimensional changes caused by natural aging, and it is tensile at high temperature The strength and impact performance at low temperature are weak, and the service life of the general zinc alloy pulley is 2 to 3 years.

2. Carbon steel pulley: a pulley made of an iron-carbon alloy material with a carbon content of less than 2% and a small amount of impurities such as silicon, manganese, phosphorus, and sulfur. The pulley made of this material has high hardness and high brittleness, and is easy to rust Corrosion, short service life.

3. 304A stainless steel bearing wheel: 304 stainless steel bearing wheel, after 100,000 continuous and destructive push-pull tests without any damage or abnormality, the normal service life is more than 5 years, and it can effectively prevent wear and bearing oil leakage. The pulley is made of nylon rubber, which is temperature-resistant and wear-resistant. It also has an anti-derailment design and a deceleration buffer design to ensure smooth and safe push and pull of the shower room.

4. Copper shaft rubber-covered pulley: This kind of pulley is more common. The middle part is yellow copper, with stainless steel beads inside, and white plastic material outside. When in use, the hardness of copper and plastic is relatively soft due to the friction of stainless steel beads. The copper shaft and the outsourcing The glue is easy to wear and tear, resulting in a larger gap between the pulleys and degumming.
