Advantages of polyurethane in heavy casters

Why choose polyurethane material for heavy casters:

Milling rice huller rubber roller, coal preparation with sieve sieve plate, universal wheel stadium track the runway, crane forklift 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 caster product, the most important is to want to see its flexibility, bearing capacity, temperature limit and so on the performance come to buy, when you choose and buy, must pay attention to. If there is any unclear, unknown, you can always search online, believe that there is a product is suitable for you!

Heavy-duty casters, especially in the working conditions of wetting media such as water and oil, are often several times to dozens of times more durable than 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.

Generally speaking, heavy casters on the rough surface of the highway or heavy load on the wheel can cause the wheel or equipment to be damaged. Therefore, stents and fasteners should be checked regularly. Tighten the loose shaft and nut and check whether the weld or support plate is damaged. Overload or impact can lead to deformation of the scaffold. The deformation of the bracket causes the heavy load to be tilted on individual wheels, causing the wheel to be damaged prematurely. For the bearing of the common plunger type casters, tighten the nuts or firmly rivets and ensure that the device holder is not bent and the insertion rod is installed correctly. Use a lock nut or lock washer when assembling casters. The device of the expansion plunger type casters should ensure that the plunger is firmly installed in the casing.
