Universal wheel is the so-called movable casters, its structure allows horizontal 360-degree rotation. Caster is a general term, including movable casters and fixed casters. Fixed casters do not have a rotating structure, can not rotate horizontally only vertical rotation. These two kinds of casters are generally used in conjunction with, for example, the structure of the cart is the front of the two fixed wheels, the back near the push handrail is two movable universal wheel.
Universal wheel is the bracket installed in the caster wheel can be rotated horizontally 360 degrees in the dynamic load or static load.
There are various materials used to manufacture the universal wheel, the most common materials are: nylon, polyurethane, rubber, cast iron and other materials. Widely used in mining, machinery and equipment, electronic equipment, medical equipment, engineering decoration, textile, printing and dyeing, furniture, logistics equipment, warehousing, turnover trucks, chassis, cabinets, equipment, electromechanical, clean room, production lines, large supermarkets and many other industries and various fields.
Roller frame refers to the friction between the weldment and the active roller to drive the cylindrical (or conical) weldment rotation device. Self-adjusting roller frame is suitable for round cylinder welding, the distance between the rollers can be adjusted according to the size of the cylinder, there are a variety of specifications for the user to choose the roller frame for large tonnage of weldments can be designed and manufactured on behalf of the roller frame. Adjustable roller frame has manual screw adjustable type, manual bolt shift type and electric slide plate shift type. By adjusting the center distance of the rollers, it is suitable for different diameters of cylinders.
