To carefully examine the friction coefficient of polyurethane casters

To carefully examine the friction coefficient of polyurethane casters, PU has the following advantages compared with plastic. Elastic memory, not brittle, wear-resisting. Polyurethane damping castor polyurethane plastic in the caster is very broad, it is to use molded production technology and has a light weight, shock resistance, wear resistance, corrosion resistance of thermoplastic polyurethane elastomer. Polyurethane damping castor wearability, is 5 - NBR Eight times. Good resistance to bending strength, good elasticity; Tensile strength and breaking elongation rate & lsquo; Low compression permanent deformation rate. The loose wheel shaft and the nut tightening and check weld or support plate for damage. Overload or crash will lead to distortion. Stent deflects the overloaded pressure distortion on individual round wheels and cause premature failure. If it is lever type caster, should be to tighten the nut or solid rivet, and ensure the equipment installation bracket without bending and pole installed correctly. Installing a caster wheel, lock nut or locking washers should be used. Expansion plug pole of castor installation to ensure that the plug rod firmly installed in a casing. Add lubricating oil regularly, wheels and bearing can use for a long time. Put grease on shaft, sealing ring and roller bearing friction parts, can reduce friction and make more flexible rotation. Under normal circumstances once every six months for lubrication. The car in a month after cleaning for wheel lubrication. Visual check the abrasion of the wheels. The wheel rotational impeded associated with fine impurities such as red, the rope. Anti-wind can cover Yin in the clutter. Castor too loose or too tight is also another factor, change damaged truckle to avoid unstable rotation. Inspect and replace the wheel after, shall ensure that use lock washers and nut tightening wheel axle. Because of loose axle can lead to friction wheel with stents and jammed. Replace the wheels and bearings should be to avoid the loss.
