How Do I Choose The Right Wheel And caster wheel
Castor is for the purpose of carrying is convenient, is used in indoor, such as building need to be engaged in the handling of all machines and all kinds of handling machine, above is the reinforcement of a man's hand, selects the universal casters and rules, no simple formula for different using environment and user's personal work habits, will affect the normal use of castor, but we will still try my best to provide the most appropriate advice for you to choose Jiang Qing caster.The selected casters should be properly used and properly installed according to the manner and conditions of their use. As a result, there are many different factors determine the choice of castor, correct selection of suitable castor, want to consider the bearing weight, use of castor field environment, rotational flexibility, the requirement of working temperature, and other special work environment requirements.

The load-carrying capacity of a single caster is determined according to the design load. Carrying capacity of the castor is the most basic and the most critical requirement of castor, and actual use of differ in thousands ways, therefore, in the actual choice caster wheel bearing capacity, should have certain safety allowance, in particular, for those who may be limited by large impact of castor, not only have to choose the caster wheel bearing capacity big, impact resistant structure and should choose different design. To ensure the caster is in safe condition for general handling work load for a long time, need to estimate the total weight of carrying objects beforehand, and then press the allowed weight to choose the appropriate castor. In the actual situation, only 3 of the 4 casters are in force, so the total weight limit should be 0.8（Don't count too much）. For example, using four casters, the measure of the total weight = each (1 only) trundle bearing load * 4 * 0.8, without the permission of the mixture of different sizes of castor, should with the minimum of bearing load of that a castor as a benchmark, to calculate maximum bearing weight as a whole. In order to be able to calculate the load capacity of various casters, it is necessary to know the weight of the transport equipment, the maximum load and the number of the single wheel and the caster. The load capacity required for a single wheel or caster is as follows:T=(E+Z)/M×N
T=Load weight for single wheel or caster
E=The weight of transport equipment
M=The number of single-wheel and casters used
N=Safety factor (about 1.3-1.5)
Select the cast-wheel universal wheel product single wheel material
Wheel material selection is also important factor: first, consider using the size of the pavement, obstacles, using ground residual material (such as iron filings, grease), environment conditions, such as high temperature and normal temperature or low temperature) and the wheels can carry the weight of the different conditions, such as to choose suitable wheel material. For example, ordinary rubber wheels cannot tolerate acid, grease and chemical, super polyurethane wheel, high strength polyurethane wheel, nylon wheel, iron wheel and high temperature wheel can be applied to different special environment. Used on rough ground, should wear resistant, flexible rubber, polyurethane or super artificial rubber wheels; In order to prevent the accumulation of static electricity generation, it is best to use a special anti-static wheel, or choose metal wheel (if the ground does not require protection).When there are a lot of corrosive media in the working environment, it should choose the wheels with good corrosion resistance. At the same time, the choice of the soft and hard wheel material is also important, in which the super polyurethane wheel and the high strength polyurethane wheel can meet your moving requirements in both indoor and outdoor ground. High strength artificial rubber wheel can be used for hotel, medical device, floor, wood floor, tile floor, etc. The nylon wheel and iron wheel are suitable for the ground floor or the ground with the material such as iron filings; The air wheel is suitable for the soft and uneven surface of the road. In addition, extreme cold and high temperature have great influence on the caster,Polyurethane wheel 45 ℃ below zero, for example, under low temperature, can rotate freely, high temperature resistant electric wooden wheel under the high temperature of 275 ℃ still turn the light.
Select the wheel of the caster wheel the size of the single wheel
Usually wheel diameter the more the more easy to drive, the greater the load capacity and at the same time, it is to protect the surface from being damaged, wheel diameter size first consideration should be given the choice of bearing and the weight of the load on the truck starting thrust to decide.
Select the bearing for the cast-roller universal wheel
Terrell bearings: turling is a special engineered plastic that is suitable for damp and corrosive places, but rotational flexibility is generally relatively high.
Roller bearing: heat treated roller bearing can carry heavy load and rotational flexibility.
Ball bearing: ball bearings made of high quality bearing steel can carry heavy loads, which are suitable for turning flexible and peaceful occasions.
Flat bearing: suitable for high and high load and high speed.

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 load (280 kg per caster) is suitable for the wheel rack of double row ball bearings with thick steel plate (5-6mm) 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 using rotating wheel frame roof plane ball bearing and ball bearing on the floor, make the castor can withstand the heavy loading, flexible rotation, impact resistance, etc. To transport valuables, you can choose to reduce the cushioning of the caster.
Select the wheel - wheel product brake device
Selection about the caster wheel braking device, mainly according to the price of castor economy, working strength, applicability, work for conventional brake has brake hub, edge is brake wheel, brake rotating type roof, just type brake wheel surface, is the brake brake wheel surface and rotating type roof and other according to the special requirements of braking device, at present, wanda wheel industry has development and production of about 200 kinds, suitable for different requirements of the caster wheel braking device.
Select the caster wheel wanxiang wheel product lubricant
About castor wheels using the environment, the temperature requirements and regional differences, as well as the guest's use habit, for castor and universal wheel grease and group also has the very big difference, which is why some castor plant and castor users easy to overlook. Different temperature requirements, pay attention to the choice of different thermal grease, in place of heavy dust environment, also note with dust cover or shield, to protect the flexibility and stability of the caster wheel rotation, effectively improve the service life of the castor products.
Analysis of the walking speed of the wheel wanxiang wheel
In the normal temperature environment, with no higher than the walking speed, on the flat ground, there is a certain stop working condition general use case. Please avoid the continuous use of the foot wheel heating (except, of course, customized casters)
According to the diameter of the wheel single wheel
A caster with a diameter of less than 75mm shall operate at a speed of 2 km/h
The speed of the caster with diameter above 100mm should be below 4 km/h
