Directional casters have no swivel structure and cannot be rotated; universal casters have a structure that allows 360-degree rotation (as shown above). Classification by application industry
Mainly divided into medical casters, industrial casters, supermarket casters, furniture casters, etc..
Medical casters to adapt to the requirements of hospitals running light, flexible steering, elasticity, special ultra-quiet, wear-resistant, anti-tangling, as well as chemical corrosion resistance and other characteristics of the special casters.
Industrial casters are mainly used in factories or mechanical equipment, a caster product, which can be selected from high-level imported reinforced nylon (PA6), super polyurethane, rubber made of a single wheel, the product as a whole whole has a high impact resistance and strength.
Supermarket casters for supermarket shelves to adapt to the mobile needs of shopping carts and shopping carts need to be lightweight and flexible characteristics of the casters developed specifically.
Furniture casters are mainly adapted to the need for low center of gravity, high load bearing furniture needs and the production of a class of special casters. According to the caster material classification
Mainly divided into super artificial rubber casters, polyurethane casters, plastic casters, nylon casters, steel casters, high-temperature casters, rubber casters, S-type artificial rubber casters Mainly in the cart, mobile scaffolding, workshop trucks and so on is extremely widely.
The simplest inventions are often the most important, and casters have this characteristic. At the same time a city's degree of development is often high and casters use how much positive correlation, such as Shanghai, Beijing, Tianjin, Chongqing, Wuxi, Chengdu, Xi'an, Wuhan, Guangzhou, Dongguan, Shenzhen and other cities of casters on the use of the rate is very high.
The structure of the casters by a single wheel mounted on the bracket and become, for installation in the equipment below to make it move freely. Casters are mainly divided into two categories:
A fixed casters Fixed bracket with a single wheel, can only move along the straight line.
B movable casters 360-degree steering bracket with a single wheel, can travel in any direction.
Industrial casters have a wide range of single wheels, varying in size, model, tire tread and so on. Choose the right wheel depends on the following conditions:
A Use of site environment.
B Product load capacity
C Working environment contains chemicals, blood, grease, oil, salt and other substances.
D A variety of special climate, such as humidity, high temperature or cold E Resistance to impact, collision and driving serenity requirements. 1, usually choose the appropriate wheel frame first consider the weight of the casters bearing such as supermarkets, schools, hospitals, office buildings, hotels and other places, due to the floor is good, smooth and carry goods lighter, (each caster bearing 10-140kg), suitable for the choice of thin steel (2-4mm) stamping molding of the plating of the wheel frame, the wheel frame is light, flexible operation, quiet and beautiful, this plating wheel frame according to the arrangement of the bead This plating wheel frame is divided into double rows of beads and single rows of beads. If often moved or carried when the application of double-row beads.
2, in factories and warehouses and other places, cargo handling is very frequent and heavy load (each caster load in 280-420kg) is suitable for the use of thick steel plate (5-6 mm) stamping and hot forging and welding of the double rows of beads of the wheel frame.
3, if used to carry heavy loads such as textile factories, automobile factories, machinery factories, etc., due to the heavy loads and long walking distances within the factory (each caster loaded at 350-1200kg), it should be selected to thick steel plate (8-12mm) cut and welded wheel frame, the movable wheel frame using a plane ball bearings and ball bearings in the base plate, so that the casters can withstand the heavy loads, rotating and flexible, impact resistance and other functions. The casters can withstand heavy loads, rotate flexibly, and resist impacts, etc.
