How to protect the zhongshan caster stents

Castor castor is a general designation, including activities and fixed castor. Castor also is what we call the universal casters, its structure is allowed to rotate 360 degrees; Fixed castor also called directional casters, it has no rotating structure, can't turn. The framework of the heavy-duty casters, usually adopt the metal materials as the main body, including ordinary steel plate stamping molding, casting molding, die forging steel molding, usually is given priority to with flat plate assembly. Heavy steel plate thickness of castor generally USES 8 mm, 10 mm, 16 mm and more than 20 mm steel plate. Currently, wanda for China petroleum system design of bearing 12 tons of track, castor, USES a 30 mm thick steel plate, plate using 40 mm, effectively guarantee the safety of the products loaded. Heavy duty castor usually adopts the double ball track, stamping forming, heat treatment. For track, universal wheel rotating plate, generally USES the force bigger plane ball bearing or needle roller bearing, cone bearing, can effectively enhance the load capacity of heavy duty castor. For special shock heavy universal wheel, rotating plate using die forging steel, molding, effectively avoid the bolt connection plate welding, a greater intensity of improve the shock resistance of castor.
