(1) Material: reinforced nylon, with high pressure and tensile load, good toughness, high elasticity and wear resistance, flame retardant, stable performance at high and low temperatures, can be used outdoors, and the content of nylon determines Nylon drag chain The service strength, wear resistance and the noise level during operation. Nylon content ranges from 5% to 17%, but it is less than 19%, generally about 30%.
(2) Resistance: oil resistance, salt resistance, and certain acid and alkali resistance.
(3) Operating speed and acceleration (the specific speed and acceleration depend on the operating conditions).
(4) Operating life.
(5) Look at the structure not only in terms of mechanics, but also in terms of appearance.
