All kinds of casters - bearing characteristics
Castor bearing a good variety of use, without it, castor, lost value. Therefore, we suggest that the ideal bearing should be suitable for their respective applications, and keeping the necessary safety margin. Besides the rotation wheel, wheel diameter and bearing, wheel bearing determines the mobility of the casters, even that only the quality of the caster. For the use of different environments, have different requirements. Factory with castor is different from firms with casters, tool for castor is different from the hospital bed with light-duty castor, shopping cart with the requirements of the caster must be completely different from those for carrying heavy load in the factory of the caster. Single ball bearing: choose high quality made of bearing steel ball bearings, can carry heavier loads, suitable for flexible rotation and peace required. Double ball bearing: selects the high quality bearing steel produced by ball bearing, it also makes the motion of the wheels and swinging amplitude fluctuation amplitude of clearance, narrowed considerably; Make the wheels when use more stable. Can carry heavier loads, suitable for flexible rotation and quiet place. Roller bearing: after heat treatment of roller bearings can carry heavier load, rotational flexibility. Bearing's spirit: spirit, is a special engineering plastics, suitable for humid and corrosive, rotational flexibility, resistance is bigger. Plane pressure bearing: suitable for high load and high speed. If so often used in some particularly heavy machinery above for carrying heavy things such as textile factory, automobile factory, machinery factory and other places, because the charge big factories within walking distance, Each trundle bearing in 350 - only 1200公斤) , therefore, should choose to thick steel plate, 8 - 12mm) 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. Used for carrying heavy things such as textile factory, automobile factory, machinery factory and other places, due to the big factories within walking distance, therefore, should choose to thick steel plate after cutting wheel frame, welding activities wheel rack flat ball bearing and ball bearing on the floor, make the trundle bearing can withstand heavy load, rotational flexibility, impact resistance, etc.
