Advantages of polyurethane with heavy-duty casters

Heavy-duty casters: why did you choose polyurethane materials milling rice huller rubber roller, coal preparation with sieve sieve plate, universal wheel stadium track the runway, forklift truck crane dynamic oil seal, elevator wheels and wheel roller skates, etc are also polyurethane elastomer. Need to mention here is that to improve the low and middle hardness, the friction coefficient of polyurethane elastomer parts, improve the bearing under the load of wear-resisting performance, can add a small amount of sulfide in this type of polyurethane elastomer aluminum and graphite or silicone oil lubricant. Heavy duty castor features do short-distance transport items can carry a lot of weight, and can according to user needs to choose different material and the bearing capacity of casters, heavy-duty casters have two different bearings can be optional, is very convenient. Choose this kind of heavy duty castor products, the most important thing is to see its flexibility performance, bearing capacity, temperature limit and so on to shopping, when you choose and buy must pay attention to cough up. If there is anything not clear, do not understand, can Internet inquiries at any time, believe there is always a product is suitable for you! Heavy-duty casters, especially in the presence of water, oil and other wetting medium work conditions, its wear resistance is often several times to dozens times of ordinary rubber materials. Metal materials such as steel, although very hard, but does not have wear-resisting, such as the Yellow River irrigated area of large water pump, the flow components through a large amount of sediment scouring metal ring and skirts, in less than a few hundred hours wear serious water leakage, the mouth of the polyurethane (pu) elastomer coating and the continuous running 1800 small ring and skirts into still not wear, so polyurethane heavy-duty casters on the wear-resisting performance has a certain advantage. In general heavy duty castor high-speed driving on rough road surface or heavy bump pressure wheels will cause the wheels or equipment damage. So, should be regularly check the bracket and fasteners. The loose wheel shaft and the nut tightening and check weld or support plate for damage. Overload or impact will lead to deformation. Stent overloading tilting deformation caused by pressure on individual wheels wheel premature failure. For bearing general lever type casters, should tighten the nut or solid rivet and ensure equipment bracket without bending and pole installed correctly. Assembly caster wheel lock nut or locking should be used when the gasket. Expansion plug pole type caster wheel device to ensure that the plug rod firmly installed in a casing.
