Heavy Duty Industrial Shock absorbing W/brake-Swivel/Rigid PU on Cast Iron Caster(Zinc-plating)

Polyurethane casters are significantly better than radial tires in terms of wear resistance, rolling resistance and tear resistance; the same size of polyurethane casters has a load capacity of 6 to 7 times that of rubber tires; its production process can be continuous and automated , There is very little waste generated in the process of production and use, and more importantly, part of the carcass of waste tires can be recycled for other polyurethane products without causing environmental pollution; and its manufacturing process is simple--liquid casting, belonging to The new type of cordless cast wheels, which are called the green tires of the 21st century, and polyurethane wheels, will be the mainstream of future automobile tire development and have broad application prospects in the automotive industry.

Polyurethane wheel is a material between general rubber and plastic. This is the most wear-resistant elastomer at present, and it is non-toxic to the human body and can be completely biodegradable. It does not need to add carbon black and some carcinogenic The functional rubber compounding agent is an ideal material for the manufacture of tire treads. The biggest feature of polyurethane casters is to maintain high elasticity within the hardness range, excellent mechanical strength, oil resistance and ozone resistance, and good low temperature performance.

 Industrial casters mainly refer to a caster product used in factories or mechanical equipment. It can be made of high-grade imported reinforced nylon (PA6), super polyurethane, and rubber. The overall product has high impact resistance and strength. . The metal parts of the bracket are made of high-quality steel plates that have been galvanized or chrome-plated with anti-corrosion treatment, and precision ball/needle bearings are installed inside by an integral injection molding method. Users can choose 3MM, 4MM, 5MM, 6MM steel plates as caster brackets.

1. The caster bracket produced by high-pressure punching machine is stamped and formed at one time, which is suitable for short-distance transportation of goods with a carrying capacity of 200-500 kg.

2. Casters of various materials and widths can be selected according to the user's different use environments.

3. Generally speaking, industrial casters can be used in various industries such as factories, workshops, commerce, and catering.

4. Different caster products can be designed according to the environmental carrying capacity required by the user.

5. Two kinds of industrial ball bearings and industrial roller bearings are optional.

How to choose suitable industrial casters?

There are many different factors that determine the choice of industrial casters, the key is the most suitable for your use. Here are some of the most important considerations.

●The load capacity determines the weight of the load, the size of the wheel, and also affects the rotatability of industrial casters. Ball bearings are suitable for heavier load requirements of 180 kg or more.

●Using field conditions Choose a wheel large enough to adapt to the cracks in the scene. Also consider the size of the road surface, obstacles and other factors.

●Special environment Each wheel adapts to different working environment, choose the best one to adapt to the special environment. For example, traditional rubber is not resistant to acids, oils and chemicals. If you want to adapt to different special environments, Dashi high-tech polyurethane rubber wheels, plastic wheels, modified bakelite rubber wheels and steel wheels are a good choice.

●Rotation flexibility The larger the wheel, the more labor-saving. The ball bearing can carry a heavier load, and the ball bearing rotates more flexibly but has a lighter load.

●Temperature limit Severe cold and heat may cause trouble to many wheels. If the casters use special grease made by Daes, the casters can be suitable for high temperatures from -40°C to 165°C.

The unique advantages of polyurethane casters make it the backbone of industrial casters in the 21st century, and the unique advantages of its performance indicators and processing technology make it the preferred material for industrial logistics casters.

The main advantages of polyurethane casters are as follows:

1. Large adjustable range of performance

A number of physical and mechanical performance indicators can be flexibly changed within a certain range through the selection of raw materials and the adjustment of formulas, so as to meet the unique requirements of users for product performance.

2. Superior wear resistance

In the presence of water, oil and other wetting media, the wear resistance of polyurethane casters is often several to several tens of times that of ordinary rubber materials. Although metal materials such as steel are very hard, they are not necessarily wear-resistant.

3. Diversified processing methods and wide applicability

Polyurethane elastomer can be molded by plasticizing, mixing, and vulcanizing process like general rubber (referring to MPU); it can also be made into liquid rubber, injection molding compression molding or spraying, potting, centrifugal molding (referring to CPU); it can also be manufactured Granular materials, like ordinary plastics, are molded by injection, extrusion, calendering, blow molding and other processes (referring to CPU). Molded or injection molded parts can also be processed by cutting, grinding, drilling, etc. within a certain hardness range.

4. Oil resistance, ozone resistance, aging resistance, radiation resistance, low temperature resistance, good sound permeability, strong adhesion, excellent biocompatibility and blood compatibility. These advantages are the reasons why polyurethane elastomers are widely used in military, aerospace, acoustics, biology and other fields.
