For heavy duty caster bracket and bearing selection,technical production plant staff mentioned: As usualwhen select caster wheel frame,we need consider the loading weight first,Such assuper markets,schools,hospitals,office buildings,hotels and other places,as the floor are smooth,and just need handing lighter objects,(each caster load weight 10kg~140kg),Suitable choice to 2-4mm stamping forming wheel frame.The frame is light,flexible operation,silent and beautiful,According to frame ball arrangement,it's have double and single row of ball frame.

If the caster need moving or transport frequently then we need use double row ball frame.In places such as factories and warehouses,cargo handing is very frequently and heavy load,each caster bearing reach 280kg-500kg.Then it's need use 5-6mm thickness welding frame with double row ball.

When the casters are used for carrying heavy loads,such as textile mills,automobile industries,machinery factories,because of it's need loading extra duty weight and running long distance,the each caster loads weight reach 500kg-1500kg or even more.Then we need use 8-12mm welding wheel frame.and use plane bearing, so that can withstand heavy-duty casters , rotating flexible, impact resistance and other functions
