Shopping Cart Casters

In the supermarket, we often see a tool – shopping cart. Shopping cart is the most common tool in the supermarket. Its existence is to help people easily load and move items in the shopping process. Its most important part is the caster at the bottom. It can be said that the caster of shopping cart is the core part of the whole shopping cart. If it is less, it will lose the labor-saving effect. Heavy loads, high barriers, and the great differences between the cold storage area and the store counter all put forward high requirements for shopping cart casters.

The flexible movement of shopping cart is due to the installation of casters, which include fixed casters and movable casters. Among them, the movable caster is also known as the universal wheel. Its remarkable feature is that it can rotate 360 degrees horizontally and drive in any direction. The flexibility of universal wheel is inseparable from its structure, so what parts does it consist of?

① Single wheel: a single wheel is a wheel

② Movable support assembly: the movable support assembly is composed of movable support, axle, nut, screw or inserting rod, excluding wheel, inner wheel bearing and shaft sleeve.

③ Shaft sleeve: the shaft sleeve is a non rotating part made of steel sleeved outside the axle, which is used for the wheel bearing to rotate and fix the wheel in the support, and the shaft sleeve needs to be equipped with a rotating shaft.

④ Rotating bearing:

A. Single layer bearing: there is only one layer of steel ball on the large track, commonly known as single row ball bearing;

B. Double layer bearing: also known as double row ball bearing, it has double-layer steel balls on two different tracks;

C. Economical bearing: it is composed of steel ball supported by upper ball plate formed by stamping;

D. Precision bearing: it is composed of standard industrial bearing.

⑤ Center rivet:

The center rivet is an integral part of the base plate and is used to fix the bolts or rivets of the rotating device. Tightening the bolt type rivets can adjust the looseness of the universal wheel caused by rotational wear.

With the development of modern commerce, there are more and more kinds of goods. Usually when people need to buy many kinds of goods, people tend to choose to go to large supermarkets with a wide range of goods, such as Carrefour, Wal Mart, RT mart and so on.
