Casters can be said to be a convenience and a common item in people's daily life. We usually think of it when we lift heavy objects. Because of its existence, our life has obvious convenience. It is common to see it in toys, toys, etc. Supermarkets, hospitals, furniture, etc., furniture caster manufacturers will simply share with you the little knowledge of casters.

Professional custom material for casters: generally PU, TPR, PP, rubber, nylon, etc.

Brakes: In terms of function, there are brake wheels, and there are universal brake brackets. The two brakes are double brakes. There are also tread brakes, positive brakes, side brakes, etc. Please contact the caster factory for details.

Installation method: Generally, screw rods, insert rods, expansion rubber sleeves, etc. can be used for medium and light loads, and bottom plates are used for heavy loads, or directly welded to the equipment. Generally, the installation methods of large companies are very rich.

Bracket selection: Divided into directional and universal, the material is generally carbon steel, can be used for various electroplating, such as galvanizing, copper plating, nickel plating, chrome plating, spraying, etc., and stainless steel brackets are also useful.

Arrangement of casters on the equipment: The arrangement is different, which not only affects the cost, but also the feeling of pushing is greatly different!

Look at the load-bearing: For casters of the same diameter, professional custom caster manufacturers will generally produce several series for different load-bearing, such as light, medium, medium, etc. The method is to make the wheels and brackets have different thicknesses or materials. When calculating the load of a single caster, a certain insurance factor should be given. When the ground is relatively flat, the load of a single caster = (total weight of the equipment ÷ the number of installed casters) × 1.2 (insurance factor); if the ground is uneven, the algorithm is, a single caster Caster load = total weight of the equipment ÷ 3, because no matter what kind of uneven ground, there are always at least three wheels to support the equipment at the same time, this algorithm is equivalent to increasing the insurance factor, more reliable, and prevent insufficient load bearing, resulting in a greatly reduced caster life or cause ACCIDENT.

In foreign-funded companies, the load-bearing size is generally selected with a pound scale: generally, the larger the diameter of the caster, the more labor-saving it is to push and the better the ability to block obstacles. Because the caster first became industrialized in the West at the end of the 19th century, the caster is generally expressed in inches, such as Most supermarket trolleys in China use 5-inch and 4-inch casters.

At present, the popular caster sizes on the market range from 1 inch to 10 inches. The commonly used sizes are 2 inches, 2.5 inches, 3 inches, 3.5 inches, 4 inches, 5 inches, 6 inches, 8 inches, 10 inches, etc. For those that need to be pushed, such as supermarket shopping carts, logistics trolleys, tool carts, etc., it is better to use 4-6 inch casters. However, if the diameter of the caster is too large, the center of gravity of the equipment will rise and the cost will increase, so comprehensive consideration must be taken. If the equipment does not need to be pushed frequently, such as furniture, refrigerators, etc., and only needs to be moved for hygiene purposes, use casters below 3 inches.

The caster looks small, but it plays a huge role, and its role is not limited, and it is an item that is really convenient for everyone.
