What is the material of the wheels of the trolley case to be silent

Rubber material can be silent.

Trolley cases generally use the universal wheel, manufacturing universal wheel material has a variety of materials, the most common materials are: nylon, polyurethane, rubber, cast iron and other materials. Among them, the rubber wheel running sound is small, low noise, mechanical smooth, with support for the body, buffer external impact with, reduce vibration, reduce temperature and other roles, by the user favorite.

Rubber wheel overhaul:

1, test the tire tread visible wear. Tire surface "grinding point" can suggest the accumulation of foreign matter, check whether the wheel bearing is broken, if the parts are not damaged can be reassembled to continue to use, if often meet the wheel by the phenomenon of debris entanglement suggests that can be assembled to avoid anti-entanglement cover.

2, universal wheel casters loose or wheel jamming can also cause "grinding point". Appropriate maintenance checks, especially check the tightness of the bolt, the amount of lubricant, replace the broken casters can enhance the rolling performance and rotational flexibility of the equipment.

3, rubber tires are seriously damaged or become slack may lead to rolling instability, load abnormalities and base plate damage and so on.

4, after checking and repairing the wheels, make sure the bolts and nuts are tightened, and use anti-loosening washers or anti-loosening nuts on all the bolts as much as possible. If the bolts are loose, tighten them immediately.
