The caster is a general term, including the active and fixed casters. The moving caster is also known as the universal wheel, whose structure allows for 360-degree rotation; Fixed casters have no rotating structure and cannot rotate. Usually, two casters are used for matching, such as the structure of the wheelbarrow, which is the two fixed wheels on the front side, and the rear side is the two moving universal wheels.
Directional casters have no rotating structure and cannot rotate;
The gimbal structure allows 360 degrees of rotation.
Classification by application industry
It is mainly divided into medical casters, industrial casters, supermarket casters, furniture casters and so on.
The medical foot wheel is designed to fit the requirements of the hospital, which is light, flexible, flexible, special ultra-quiet, wear-resistant, anti-winding and chemical resistant.
Industrial casters is mainly refers to a caster wheel used in machinery factory or products, it can be imported from advanced reinforced polyamide (PA6), super single wheel made of polyurethane, rubber, product integral whole with high impact resistance and strength.
Supermarket casters are specially designed to fit the mobile needs of supermarket shelves and the flexible and flexible features of the shopping cart.
The furniture caster is a kind of special casters for the need of low center of gravity and high load bearing.
According to the material classification of casters.
It is mainly divided into super artificial rubber casters, polyurethane casters, plastic casters, nylon casters, steel casters, high-temperature casters, rubber casters, and S type artificial rubber casters.
It is widely used in wheelbarrow, mobile scaffolding, workshop truck and so on.
The simplest invention is often the most important, and the caster has it. At the same time developed level of a city often used with castor is related to how much, like Shanghai, Beijing, tianjin, chongqing, wuxi, chengdu, xian, wuhan, guangzhou, dongguan, shenzhen and other cities of castor utilization rate is very high.
The casters are constructed from a single wheel mounted on a bracket, which is installed under the device to allow it to move freely. There are two main types of casters:
A.Fixed casters are fixed with a single wheel and can only move in a straight line.
B.The supporting bracket with a 360-degree turn is equipped with a single wheel and can travel in any direction at will.
The single wheel of the industrial caster is varied and varies in size, model and tyre.
Choose the right wheels for the following conditions:
A.Use the site environment.
B.The carrying capacity of the product.
C.The work environment contains chemicals, blood, grease, oil, salt and other substances.
D.All kinds of special weather, such as humidity, high temperature or cold E to resist impact, collision and quiet requirements.
Usually choose suitable wheel rack first consider the weight of the caster wheel bearing such as supermarkets, schools, hospitals, office buildings, hotels and other places, because the floor is good, the smooth handling of the goods is lighter, (each trundle bearing in 10-140 - kg), suitable for selection (2-4 mm) with a thin plate stamping plating wheel frame, the wheel frame is light, flexible operation, quiet and beautiful, the plating wheel frame in accordance with the ball bearing arrangement is divided into double row bead and single bead. Apply double row beads when moving or moving.
In places such as factories and warehouses, cargo handling is very frequent and heavy (280 to 420kg per foot wheel) is suitable for the wheel rack of double row ball with thick steel plate (5-6 mm) stamping and welding .
If used for carrying heavy things such as textile factory, automobile factory, machinery factory and other places, because the charge big factories within walking distance (caster wheel bearing only at 350-1200 kg) each, therefore, should choose (8-12 mm) with a thick plate after cutting wheel frame, welding activities wheel rack flat ball bearing and ball bearing on the floor, make the castor can withstand the heavy loading, flexible rotation, impact resistance, etc.
