How to choose caster wheel bearings?
There are many kinds of bearings used on caster wheel . Without it, caster wheel lose their value. Therefore, we suggest that the ideal bearing should be suitable for the respective application, and ensure that there is a necessary safety margin. There are different requirements for different use environments. The caster wheel used in factories are different from the caster wheel used by businesses, the caster wheel used by tool carts are different from the light caster wheel used in hospital beds, and the requirements of caster wheel used for shopping carts are completely different from those used in factories to transport heavy loads.
◆ Single ball bearing: Ball bearing made of high-quality bearing steel can bear heavier load and is suitable for occasions requiring flexible and quiet rotation.
◆ Double ball bearing: Ball bearing made of high-quality bearing steel, it also makes the gap between the left and right swing of the wheel and the swing amplitude of the up and down greatly reduced; makes the wheel more stable when used. Can bear heavier loads, suitable for flexible and quiet occasions.
◆ Roller bearing: The heat-treated roller bearing can bear heavier load, and the rotation flexibility is general.
◆ Terling bearing: Terling is a special engineering plastic, suitable for wet and corrosive places, with general flexibility of rotation and large resistance.
◆ Plane pressure bearing: Suitable for occasions with extremely high load and high speed.
Therefore, it is often used on some special heavy machinery. 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 caster wheel is carried at 350-1200kg), it should be selected The wheel frame is welded after being cut with a thick steel plate (8-12mm). The movable wheel frame uses flat ball bearings and ball bearings on the bottom plate, so that the casters can bear heavy loads, rotate flexibly, and resist impact.
