How to choose a suitable for your use of castor

Author:   Time:2015/5/13 10:18:47


A, how to select the appropriate castor

1, choose castor material: first consider using the road, the size of the obstacle, the use of ground residual material (e.g., iron filings, grease), environment conditions, such as high temperature and normal temperature or low temperature) and castor can carry the weight of the different conditions, such as to determine the choice suitable castor material. For example: rubber wheel can’t acid, oil and chemicals, super polyurethane wheel, high-strength polyurethane wheel, nylon wheel, steel and high temperature resistant chakras can apply to different special environment.

2, calculating weight capacity: in order to be able to calculate the load capacity of various casters need must know the weight of transport equipment and maximum load and the number of single wheel and castor. A single wheel load capacities as needed or castor calculation is as follows: T = (E + Z)/M (N: - T = single wheel or castor to loading weight; - E = weight of transportation equipment; - Z = maximum load; - M = the number of single wheel and castor used; - N = safety coefficient (1.3 1.5).

3, determine the wheel diameter size: usually caster 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.

4, castor material soft hard choices: usually have nylon casters, super polyurethane, high-strength polyurethane wheel, high strength synthetic iron, iron, cheer. Super polyurethane wheel, high-strength polyurethane wheel in both indoor and outdoor floor, can meet the requirements of your handling; High strength synthetic lugs can apply to hotels, medical apparatus and instruments, floors, wooden floor, ceramic tile ground for low noise quiet on the ground when walking driving; Nylon wheel, wheel which can be applied to uneven or there are materials such as scrap iron on the ground; While pep talk round applies to soft light load and road surface is not flat.

5, rotational flexibility: single wheel rotation, the more the greater the effort, roller bearings can carry heavier load, rotational resistance is larger: single wheel installed on the quality of bearing steel ball bearing, can carry heavier load, turn the lighter, flexible peace.

6, the condition of temperature, cold and high temperature occasion has much effect on the caster wheel, polyurethane wheel under 45 ℃ low temperature below zero, rotating flexible, high temperature resistant light wheel under the high temperature of 275 ℃.


Second, how to select the appropriate wheel rack

1, 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. If often move or application of double row in the bead.

2, in the place such as factories and warehouses, cargo handling is very frequent and heavy load (caster wheel bearing only at 280-420 kg) each chooses to fit (5-6 mm) thick steel plate stamping hot forging and welding of double row ball wheel.

3, if used for carrying heavy objects such as textile, automobile factories, 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.


Third, choose the suitable bearing

1, the spirit, bearing, spirit is a special engineering plastics, suitable for humid and corrosive, rotational flexibility, resistance is bigger.

2, roller bearing: after heat treatment of roller bearings can carry heavier load, rotational flexibility.

3, ball bearing, selects the high quality bearing steel ball bearing is made and be become, can carry heavier loads, suitable for flexible rotation and peace required.

4, plane bearing: suitable for high and very high load and high speed
