Select the appropriate wheel frame to extend the life of the caster.
1, choose suitable wheel rack first consider the weight of the caster wheel bearing such as supermarkets, schools, hospitals, office buildings, hotels and other places, because the floor is good, the smooth handling of the goods is lighter, (each trundle bearing in 10-140 - kg), suitable for selection (2-4 mm) with a thin plate stamping plating wheel frame, the wheel frame is light, flexible operation, quiet and beautiful, the plating wheel frame in accordance with the ball bearing arrangement is divided into double row bead and single bead. Apply double row beads when moving or moving.
2, in the place such as factories and warehouses, cargo handling is very frequent and heavy load (caster wheel bearing only at 280-420 kg) each chooses to fit (5-6 mm) thick steel plate stamping hot forging and welding of double row ball wheel.
3, if used for carrying heavy objects such as textile, automobile factories, factory machinery factory and other places, because the charge big factories within walking distance (caster wheel bearing only at 350-1200 kg) each, therefore, should choose (8-12 mm) with a thick plate after cutting wheel frame, welding activities wheel rack flat ball bearing and ball bearing on the floor, make the castor can withstand the heavy loading, flexible rotation, impact resistance, etc.
