The Introduction of Casters
Castor is a general term, including fixed and removable casters. Casters activities also is what we call the universal wheel, its structure allows a 360 degree rotation wheels are fixed without rotating structure and can not rotate. Usually two casters are generally paired with, such as trolley structure is in front of two directional wheels, behind near promote the handrail is two universal wheels.

Usually two casters are generally paired with, such as structure of cart is in front of two fixed wheels, behind near promote the handrail is two universal wheels.
The Application of Casters
The Application of Casters Mainly in the trolley, mobile scaffolding, shop goods vehicles and other aspects of a very wide range. The most simple inventions are often the most important, it have the characteristics of casters. At the same time a city developed level often with casters use how much is, like Mumbai, Delhi, Banglore, Hyderabad, Ahmedabad, chennai , Kolkatta, Surat and other cities in the casters use rate is very high. Castor structure consists of a single wheel is mounted on the support and, for installation in equipment following its move freely. Casters are mainly divided into two categories: A fixed castors fixed bracket with a single wheel, only moving along a straight line. Support with B casters 360 degrees turn on a single wheel, can travel in any direction.
Industrial casters single round variety, in size, type, tire surface is different.
Select the right wheels for the following conditions:
- use of site environment.
- Weight of products.
- work environment containing chemicals, blood, grease, oil, salt and other substances.
- A variety of special climate, such as humidity, high temperature or cold.
- impact, collision and travel quiet requirements.
The classification of casters
According to whether or not to classify Divided into directional and non directional caster casters (i.e. universal casters). Directional casters without rotating structure, can not rotate; the structure of the universal casters allow 360 degree rotation.
According to the application of industry classification Mainly divided into medical casters, industrial casters, supermarket casters, furniture casters etc..
Medical casters in order to meet the requirement of the hospital running lightweight, flexible steering, elastic, special ultra quiet, wear-resistant, anti winding and chemical corrosion resistance and other characteristics, special casters.
Industrial casters is mainly refers to the plant or machinery and equipment of a caster products, it can be reinforced polyamide (PA6), super polyurethane, rubber is made of single wheel, the overall product all has very high impact strength and using advanced imported.
In order to meet the needs of mobile casters castors supermarket supermarket shelves and shopping cart characteristics to be flexible and specialized development.
A class of special production casters furniture casters mainly for furniture need to adapt to the low center of gravity, high bearing.
According to the material classification of caster Can be divided into super artificial rubber casters, polyurethane casters, plastic caster wheel, nylon casters, steel casters, resistance to high temperature wheel, rubber casters, s type artificial rubber casters.
Castor Material
Polyurethane, Cast Steel, Cast Iron, Nitrile Rubber Tyred (NBR), Acrylonitrile Butadiene rubber, Natural rubber wheel, Silicon Fluorine Rubber Tyred, Chlorine neoprene rubber, Butyl rubber , Silicone rubber SILICOME, Three ethylene propylene rubber rubber (EPDM), Fluorine rubber rubber (Viton), Hydrogenation Ding nitrile (HNBR), Polyurethane rubber wheel, Rubber and plastics, Pu rubber wheel, PTFE rubber wheel (PTFE parts), Nylon gear, Poly formaldehyde rubber round, Peek rubber wheel, PA66 gear, POM rubber wheel, Engineering plastic parts (such as high strength properties of PPS, peek tubing, etc.).
How to choose the casters for you to use?
1, the choice of wheel material: first consider the size of the pavement, obstacles, the use of site residues (such as iron, oil), environmental conditions (such as at room temperature and high temperature or low temperature) and the wheel can bear the weight of different conditions to determine the choice of suitable wheel material. For example: rubber wheel is not acid, oil and chemicals, super polyurethane wheels, high strength polyurethane wheel, nylon wheel, steel wheel and a round of high temperature can apply to different special environment.
2, the calculation of bearing weight: to to calculate the load capacity of various casters need, must know the transportation equipment weight, maximum load and the number of single wheels and casters.
The calculation of load capacity of a single wheel or caster required:
T= (E+Z) N * /M:
—T= single wheel or caster required bearing weight;
Weight of —E= transportation equipment;
The maximum load of —Z=;
The number of the single wheel and wheel —M=;
—N= safety factor (about 1.3 – 1.5).
Decision to wheel size: usually wheel diameter the greater the more easy to promote, greater load capacity also is to protect the ground from damage, wheel diameter size selection should first consider the bearing the weight and load handling car starting thrust to decide.
4, the wheel material soft and hard choices: usually wheel nylon wheel, super polyurethane wheels, high strength polyurethane wheels, high strength artificial rubber tire, iron wheel, pump wheel. Super polyurethane wheels, high strength polyurethane round regardless of in the indoor and outdoor ground driving, can meet your requirements of handling; high strength artificial rubber tire can suitable for hotel, medical equipment, floors, wood floors, ceramic tile ground, etc. when walking noise small quiet ground uplink driving; nylon wheel, iron wheel applicable on uneven ground or ground on a site of iron filings and other substances; boost wheel is used in light load and pavement soft flat occasions.
5 and rotational flexibility: single wheel rotation is more labor-saving and roller bearings can carry heavier loads, rotation of greater resistance: single wheel installed on the quality of bearing steel ball bearings, bearing heavy load, turning more portable, flexible quiet.
6, temperature conditions: effect of cold and high temperature of the occasion of casters, polyurethane wheels at minus 45 DEG C low-temperature, turning is flexible, resistant high temperature round under high temperature 275 degrees rotation is easy.
Special note: because a plane determined by 3 points, when the caster for the number 4, according to 3 load calculation.
