There are many types of casters on the market, with various qualities. If the price is high, it must have its selling points, such as oil resistance, anti-static, high temperature resistance, corrosion resistance, impact resistance, shock absorption, ground protection, and quietness.
1. Generally, when choosing a suitable wheel frame, first consider the weight carried by heavy-duty casters, such as supermarkets, schools, hospitals, office buildings, hotels, etc. Because of the good floor, smooth and light cargo, (each heavy-duty caster carries a load of 10- 140kg), suitable for choosing the electroplated wheel frame stamped and formed of thin steel plate (2-4mm). Its wheel frame is light, flexible in operation, quiet and beautiful. The electroplated wheel frame is divided into double-row balls and single-row balls according to the ball arrangement. If it is often moved or transported, double-row beads should be used.
2. In places such as factories and warehouses, where the cargo is moved frequently and the load is heavy (each heavy caster carries a load of 280-420kg), it is suitable to use double-row balls that are stamped, hot forged and welded with thick steel plates (5-6 mm) Round frame.
3. If it is used to carry heavy objects such as textile factories, automobile factories, machinery factories, etc., due to the heavy load and the long walking distance in the factory (each heavy caster carries 350-1200kg), thick steel plates (8- 12mm) After cutting the welded wheel frame, the movable wheel frame uses flat ball bearings and ball bearings on the bottom plate, so that the heavy casters can withstand heavy loads, rotate flexibly, and resist impact.
