Types of wheel bearings and their differences
Specificity of mobile equipment
Carts are an irreplaceable attribute of utility services. They are usually not noticed in everyday life, but without such devices, moving the load would turn into a big problem. For this reason, the condition of their nodes must be carefully monitored. One of the most important elements of the bogie design is the swivel wheel support. It is thanks to her that a single loader easily manipulates large weights. Manufacturers use various materials in the manufacture of wheel bearings:
polyvinyl chloride (PVC);
nylon and stuff.
There are many different types of wheel bearings, they are used in different areas. Allocate household, "general use" (for installation on garbage containers, supermarket trolleys, office furniture, etc.), industrial, for servicing production processes. Carts are indispensable in warehouses, food processing enterprises, metallurgical plants.

The advantage of supports made of different materials
Each raw material for the manufacture of equipment is characterized by certain properties. This affects the operational capabilities of the wheels and bogies, as well as their price. From an economic point of view, it is best to use wheels with gray or black rubber tires. They are inexpensive, but quite powerful. Of the shortcomings, one can single out a clear trace that the carts leave on the surface. These types are widely used in industrial plants.
Polyurethane wheel bearings are more durable. Due to their high resistance to wear, they are used not only indoors, but also outside. One of the most acceptable options for widespread use. Steel wheels are distinguished by their high strength and reliability. However, their disadvantages include dents that remain when the cart is moved on wooden surfaces.
A distinctive feature of PVC supports is elasticity. Therefore, such wheels are effective where you have to transport cargo by wires. Nylon supports do not differ in durability, but they have a low price. If the cart is not used very intensively, this is by far one of the best options. In this case, buying nylon wheels will save you a lot!
As already mentioned, the wheel bearings are divided according to purpose, used in areas from household to industrial. There is another classification - by the type of bracket. According to her, the wheels are fixed and swivel. The latter variation is the most common, so let's take it as an example. A standard wheelset consists of the following components:
Some supports work without a bracket. These wheels are installed on pallet trucks as main wheels. Sometimes they are used as drive wheels, as well as components and spare parts. One of two types of brakes is used on the brake wheel bearings:
Pedal. Sometimes it protrudes from under the cart and is activated by pressing the foot. It functions according to the principle of wheel fixation and swivel mechanism.
"Butterfly". This type of brake, like the previous example, can be applied and removed with your foot. Unlike a pedal, it only fixes the wheel and does not affect the swivel mechanism.
Wheels without brakes are also very common. Their principle of operation is that they rotate 360 degrees relative to the trolley platform. The support fork is equipped with stiffening ribs, which gives additional lateral stability.
The process of choosing the right wheel
In some industries, such as warehouses or repair shops, carts are an important technical unit. If their condition is not working, this circumstance will be reflected in production processes. Of course, if it is not possible to transport the mill or crane unit directly to the place of repair, then its timely repair is questionable. As a result, the launch of equipment is slowed down, which should carry out processes and make a profit.
Attention! The economic component, although important, is not the key reason for keeping the wheel assemblies in working order. The fact is that any breakdown of them, along with expenses, can provoke injury not only to the loader, but also to people nearby. At any enterprise, compliance with safety regulations related to human health and life is a priority.
One of the conditions for the smooth operation of wheel bearings is considered to be their correct choice. This is a responsible process consisting of three stages:
Analysis of the main area where the cart will be used. Before choosing the wheel bearings, the floor or road surface, the features of the environment, are carefully studied.
