Rubber casters Casters & Wheels polyurethane casters casters selection method 
 There are many different factors determine the choice of casters, the key is the most suitable for your use. The following recommended several options for the casters. 

 First, the carrying capacity 

 Determined according to the design load of the single casters need to reach the carrying capacity. The carrying capacity of the casters casters the most basic and most critical requirements, and the actual use of the situation be different, so the actual choices of the carrying capacity of the casters, you should leave some safety margin, the most commonly used four-wheel type installation, for example, usually according to the following two methods to select: 

 Three casters to withstand the full weight of the choices. A caster vacant, this method is applicable to the shipment of goods or equipment during the move, casters withstand the momentum, the occasion of the poor ground conditions, especially in the case of large total weight. 

 Withstand the total weight of 120% select four feet round. This method applies to the ground in good condition, the shipment of goods or equipment during the move, castors to withstand the impact of smaller occasions. 

 Needs to be noted, for those casters will be a great impact not only to choose the carrying capacity of the casters, and should use the special design of the impact structure. 

 Second, the use of the site conditions 

 Under actual working conditions of the casters choice of wheel material. Wheels direct contact with the ground, are susceptible to invasion and erosion of the ground and various objects on the ground and surrounding environment in a variety of corrosive media, if you choose properly, will greatly shorten the life of the casters, the work environment will be on wheels the use of impact. 

 Rough ground, should be wear-resistant, elastic rubber, polyurethane or super artificial rubber tire sub; special high or low temperatures, or large temperature difference between the working environment should be selected metal wheels or a special resistance to high temperature wheels; in place to prevent accumulation of static electricity, the best use of special anti-static round metal wheel can also be used (if the ground is not the protection of it); work environment, there are a lot of corrosive media, it should choose has good corrosion resistance wheels. 

 Selected the most appropriate model based on the use of the environment on casters adaptability. 

 Rubber casters Casters & Wheels polyurethane casters three rotation flexibility 

 Operation of high-precision ball bearings particularly smooth and flexible, especially for high-end equipment and a quiet environment; Patel spiritual quality DuPont engineering plastics bearing is widely adapted to a variety of corrosive media; elaborate needle bearing is still easily under the weight of freely; for the protection of a beautiful floor, use a soft rubber, polyurethane and super artificial rubber tire; avoid leaving ugly round of India on the ground, select a special gray rubber wheels, polyurethane wheels, super- synthetic rubber tire and wheel round India ...... 

 Fourth, the temperature requirements 

 Cold and heat on a lot of wheels are likely to cause trouble, the best selection of wheels compatible with the ambient temperature. 

 Five other 

 In accordance with a variety of special requirements, you can select the appropriate accessories (for details see annex). Such as dust caps, seals and anti-wrapped cover and so can keep the casters turn the area clean, to prevent the entanglement of a variety of fiber, so that the casters to long-term use is still flexible as ever; single valves and dual brake device can effectively prevent the castors rotate and steering, so you can stay in any position.
