Choice of soft and hard wheel material: usually wheels have nylon wheel, super polyurethane wheel, high strength polyurethane wheel, high strength artificial rubber wheel, iron wheel, and pneumatic wheel. Super polyurethane wheel and high strength polyurethane wheel can meet your transport requirements in both indoor and outdoor ground. The high strength artificial rubber wheel can be used in hotel, medical equipment, floor, wooden floor, tile floor, etc. The nylon wheel and iron wheel are suitable for the ground floor or ground with iron filings and other materials; And the air wheel is suitable for light weight and uneven road surface.
5, rotational flexibility: single wheel rotation, the more the greater the effort, roller bearings can carry heavier load, rotational resistance is larger: single wheel installed on the quality of bearing steel ball bearing, can carry heavier load, turn the lighter, flexible peace.
6, the condition of temperature, cold and high temperature occasion has much effect on the caster wheel, polyurethane wheel under 45 ℃ low temperature below zero, rotating flexible, high temperature resistant light wheel under the high temperature of 275 ℃.
