How to choose the suitable size of industrial caster?

Industrial casters mainly refers to a castor products used in factories or machinery equipment, the whole product has high impact resistance and strength, the choice of industrial castor for the entire project construction efficiency has a very significant impact, therefore, the choice of the right industrial castor is very important.


Generally, we can divide the industrial casters into many different models according to different sizes. These products can be designed according to the needs of users, and can also be selected and purchased on the market. Casters have their own advantages and disadvantages, so how can we buy suitable products? Here Huanxin castors to help you understand:

1, first of all, to choose the right material: usually universal wheel material: nylon, rubber, polyurethane, artificial rubber, iron core package polyurethane, cast iron, plastic, etc. The polyurethane wheel can meet your handling requirements both indoors and outdoors on the ground; Artificial rubber wheel is suitable for hotel, medical equipment, wood floor, ceramic tile floor and other requirements of walking noise is small, quiet ground; Nylon wheel, iron wheel is suitable for uneven ground or ground with iron, iron filings and other materials of the site.

2. How to choose caster bracket correctly: Usually choose suitable castor bracket must first consider castor can bearing the weight of the highest, such as supermarkets, schools, hospitals, office buildings, hotels and other places, because the ground is good, the smooth handling of the goods is lighter, (each trundle bearing in 50-150 kg), suits to choose 3-4 mm with a thin plate stamping plating wheel frame, the wheel frame is light, flexible operation, Quiet and beautiful. The plating wheel frame can be divided into double row of beads and single row of beads according to the ball arrangement. If it is often moved and handled, double row of beads should be used. In factories and warehouses and other places, the cargo handling is very frequent and heavy load (each castor bearing 150-680kg), it is suitable for the selection of thick steel plate 5-6mm stamping hot forging and welding of double row ball bearing wheel frame; If it is used for carrying heavy objects such as textile factories, automobile factories, machinery factories and other places, because of the heavy load and long walking distance (each caster bearing in 700-2500kg), it should be selected to use thick steel plate 8-12mm cut after welding wheel frame, movable wheel frame using plane ball bearings on the bottom plate, The casters can simultaneously have high bearing, flexible rotation, impact resistance and other functions.


3, how to calculate the bearing weight of casters: in order to be able to calculate the carrying capacity of various casters, it is necessary to know the weight of transport equipment, the maximum load and the number of casters used. The load capacity of a caster is calculated as follows: T=(E+Z)/M×N: T= the load capacity of a caster; E = dead weight of transport equipment; Z= maximum load; M= number of casters used; N= safety factor (about 1.3-1.5).

4, choose the diameter of the castor size: usually the larger the diameter of the wheel, the easier it is to push, the greater the load capacity, but also better to protect the ground from damage. The selection of wheel diameter should consider the load bearing weight and the starting thrust of the truck under the load.

5, keeping the rotation flexibility of the wheel: the greater the rotation of the single wheel, the more energy saving, the greater the bearing capacity of the ball bearing, the smaller the resistance when the rotation, so the single wheel installed on the high quality ball bearing, can bear a heavier load, rotation is more light, flexible and quiet.

6, the temperature of the product: cold and high temperature occasions have a great impact on the castor, so should be for their own transportation environment to choose the right castor, such as polyurethane wheel can rotate at a low temperature of minus 45℃ flexible freely, high temperature resistant wheel at a high temperature of 270℃ light rotation.

After the casters are selected and used normally, standard daily maintenance can prolong the service life of the casters. It is believed that the maintenance of the casters should be carried out from several details. The specific analysis is as follows:

1. Caster loosening or wheel stuck will cause the phenomenon of “grinding flat”. Proper maintenance inspection, especially to check the tightness of bolts, the amount of lubricating oil and the replacement of damaged casters can enhance the rolling performance and rotation flexibility of the equipment.

2. Check whether the wheel bearing is damaged. If the parts are not damaged, they can be reassembled to continue to use.

3. After checking and repairing the wheels, make sure that the bolts and nuts are tightened, and use anti-loose washers or anti-loose nuts on all bolts as far as possible. If the bolts are loose, tighten them immediately. If the wheel mounted in the bracket is loose, the wheel will be damaged or can not turn, shortening the service life of the wheel.
