Castor wheels, in fact, the choice of hard polyurethane tire surface is more suitable for walking on the floor of the soft and smooth, and the soft tyre tread more easily on the hard floor or outdoor ground roll, but chose to comprehensive analysis for the type of the wheels of all special ground track, sink, the door, the steps, elevator entrance, aperture, wharf steel plate, and so on. The soft the wheels is larger, the more easily the track or similar on the surface of the rolling. Teach you a simple method to choose the suitable pu castor despite the lack of a simple model how to choose the suitable pu castor, but provided the following information and the back of the classification of a series of polyurethane casters, operation and maintenance aspects of the introduction will help you understand how to safely use pu castor products, how to prolong its service life. Load and the first consideration when selecting pu castor wheels size equipment itself and can carry the weight of the maximum weight, in general, the greater the the total weight, will choose the larger the size of the wheel, the wheels, the greater the weight can be more dispersed, the easier it is to walk on the uneven ground. Pu castor manufacturers second consider the pu castor itself can carry the load. The weight of the equipment itself and load divided by the sum of the weight of the object using the number of pu castor, got is each pu castor should bear the weight of usually, when we actual installation will choose to bear the weight of pu castor is greater than the weight calculation. So you can avoid accident happens affect the normal use of polyurethane casters. Pu castor market price ball bearing: suitable for for the wheel load after the rotation of the demanding situation, only smaller force can make its rotation, with smaller force can keep the motion state. ROM the bearing: this type of bearings are capable than ball bearings of the same size. Used in industrial fields that require high bearing weight. A cost-effective bearing, bearing's spirit: waterproof performance is good, can steam washing, salt resistance, corrosion resistance. Soft tire surface can protect the surface from being damaged, the solid soft iron, TPR wheel, high modulus of rubber and PU wheels can be quiet operation, and to the greatest extent to protect the floor. Steel or cast iron wheel would damage the floor, often used for industrial equipment. PU wheel as the core of PU wheel, suitable for both to protect the floor and high load bearing. The wheel bearing sliding bearing: the wheels installed directly axle housing and shaft. Pu castor manufacturers & # 8203; How to choose suitable pu castor for equipment is very important, if pu castor with product equipment collocation is improper, equipment users are likely to be hurt because of this, if you are not sure which one should choose pu castor, you can turn to the relevant security or engineering consultant, the consultant must understand product and use. Pu castor and wheels of different types and models.
