Universal caster wheel is the so-called movable castor, which means that installed on the caster stents can rotate 360 degrees under the dynamic or static load level. So what factors need to pay attention to when choosing castor? Materials selection: there are many kinds of universal caster wheel material, the most common are: pu, PVC, TPE, nylon, PP, rubber, cast iron, etc. Recommend the use of polyurethane wheels, because it has high mechanical strength and oxidation stability, high flexibility and resilience, and excellent oil resistance, solvent resistance, water resistance and fire resistance. Performance, thus has a wide range of USES, there are two kinds of iron core of polyurethane and plastic core polyurethane option. Universal caster and scope of application: widely used in mining, mechanical equipment, electronic equipment, medical equipment, engineering, decoration, textile, printing and dyeing, furniture, logistics equipment, storage, revolving cars, chassis, cabinets, equipment, machinery, dustless workshop, production lines, large supermarkets and other industries and fields. Temperature conditions: the choice of cold and hot occasion had a great influence on casters. For example, polyurethane wheels in - With low temperature, 45 ℃ and rotation is flexible. High temperature resistant wheels under the high temperature of 275 ° C slight rotation, so should pay attention to when choosing universal casters use occasion. Temperature requirements. Bearing and wheel size options: bearing into the ball bearing, needle bearing, and Teling bearing. Rotating flexible and comfortable. Recommend the use of ball bearings and needle roller bearings. Different sizes of wheel load, the wheel width, total height and rotating radius are different. If universal caster wheel brake: tell from the function, the caster wheel brake with brake wheel, brake bracket. Two brake is double brake, as well as the tread brake, brake, side brake, etc. The brake type should be selected based on the specific purpose. situation
