For shower room, besides of toughened glass, the pulley is also an important part of. Only high quality pulley can ensure the service life of the shower room and the safety of consumers. Many pulleys are on the market with a nylon jacket, but there were things around - — Bearings. Bearing on the service life of the roller length has played a decisive factor, for now, see at most there is copper, carbon steel, zinc alloy, stainless steel shaft, one of the best quality is 304 stainless steel material, copper second choice, the rest of the material is belong to the poor materials, service life is relatively short. That import 304 stainless steel, stainless steel bearings, wheel bearings round by 100000 times continuity, destructive push-pull test without any damage or abnormal material, normal service life generally can reach more than 5 years, can effectively prevent wear and bearing oil leakage. Pulley used nylon bag adhesive, heat resistance, wear-resisting and have derailment prevention design, with a slow buffer design, guarantee the shower room of push-pull flow and safety. Second, copper shaft package plastic pulley shaft copper plastic pulley is the most common, the middle part is yellow, inside with a stainless steel beads, outside white plastic material. When using stainless steel bead friction happens, copper and plastic soft hardness, copper shaft with outsourcing adhesive wear easily, cause pulley gap is more and more big, finally come unglued. Three, carbon steel pulley carbon content less than 2%, and has a small amount of silicon, manganese, phosphorus, sulfur and other impurities of iron carbon alloy material production of pulley, the pulley high hardness and brittleness material, easy to rust, corrosion, short service life. The pulley, zinc alloy with zinc alloy material production base material to join other elements of the pulley. Zinc alloy low melting point, good liquidity, easy fusion welding, brazing and plastic processing, deformed material easy to recycle and remelting; But low creep strength, corrosion resistance is poor, prone to natural aging, caused by changes in the tensile strength at high temperature and low temperature impact properties are weak, generally the service life of zinc alloy roller in 2 ~ 3 years.
