The roller is an important part for any conveyor belt. Its reliability and quality largely determine how well the machine itself will work, whether it is able to perform its functions. The conveyor roller can serve from two to 15 years, depending on the conditions in which it is operated. It is necessary to comply with certain requirements so that the structure really fulfills its purpose and can last as long as possible.

What do we pay attention to first of all?

Usually, technical and purchasing policies become the main factors on the basis of which one or another type of equipment is purchased. The same can be said about the rollers for the conveyor. In some cases, they prefer cheaper models and options, not paying attention to quality issues. For others, a more reasonable and far-sighted approach is more important, then they already look at how operational indicators correlate with each other, pay attention to future conditions. The following information will be provided that will certainly be useful for such enterprises.

Modern production and its features

Each manufacturer may vary the ratio between cost and assembly. This is because everyone tries to cater to the individual requirements of any customer who asks for help. The conveyor roller is currently available in 160 sizes. Each of them has its own characteristics, advantages and disadvantages. There is also a special, shock-absorbing variety. It is best to choose the manufacturer who really pays attention to quality when producing conveyor rollers. It is better to comply with GOST.

About different modifications

Now rollers can be prefabricated and non-prefabricated. But there are not many enterprises that can produce both of these options at once.

Less weight is perhaps the main characteristic if a non-separable type conveyor roller is purchased. Such structures, if necessary, are easily replaced and transported, they weigh little and are relatively cheap. The product is quite simple, but there is only one drawback - you can only use it once. However, it can also become indispensable, for example, if the enterprise uses these types of parts as consumables. Despite the low price, non-separable rollers remain quite reliable.

In continuous production, they can be successfully used when repair and maintenance conditions are very difficult, in environments with aggressiveimpact. In such an environment, the conveyor roller rusts faster than the bearing wears.

Affordable alternative

The collapsible design will be the best option for enterprises where there are no problems with repairs. Such a product can be re-installed on the unit after all maintenance work has been carried out. Hubs are attached to the pipe for welding along the entire circumference. Thanks to this, the connection becomes very reliable and rigid. The service life is increased, even several cycles do not become a problem for this type of product.

In turn, the collapsible type is divided into heavy and medium series. The design of the bearing unit remains in any case the same type, any conveyor rollers fall under this rule. The production of each of the groups provides only differences in the type of bearings themselves. In the heavy series, the bearings are more powerful, thanks to which the reliability is increased, even operation in difficult conditions will not be a problem. For heavily loaded main conveyors, this option is simply irreplaceable.

Important quality criteria

Ease of use, durability and reliability are perhaps the main requirements that apply to any quality product, including in this area. Therefore, it is worth choosing for close cooperation only those enterprises that are able to meet these requirements. In many cities today they produce a conveyor roller. Kemerovo is no exception.

Additional requirements

Among other things, attention should be paid to the fact that the bearing itself is reliably protected from dirt and dust from the outside, scale from the inside. The 80 series sealed bearing is used to solve this problem in a non-separable design. A rubber seal provides additional protection when these conveyor rollers are produced. The price remains quite affordable. The cost of rollers depends on their size and manufacturer and starts at about 150 rubles.

If a collapsible version is purchased, the bearing is protected with a special cap from the inside, a double labyrinth seal. Simultaneous boring of the pipe from both sides must be carried out in order to avoid the beating of the roller, which disables the mechanism.

A little about wear

Conveyor technology evolves and changes as the same processes take place in the direction of trade and production. There are more and more new materials, methods of cargo delivery.

The conveyor itself is quite widespread. At the same time, such equipment is one of the most expensive. And the transport rollers wear out pretty quickly. We have to install additional parts so that the production process does not stop.

About technical specifications according to GOST

According to the documents, the diameter of conveyor rollers is from 89 to 159 millimeters.

The length can reach two thousand mm.

According to the shape of the product of this groupmost resemble a cylinder. There is a special labyrinth seal to keep dust out. Regarding the ends of the axles, the customer himself makes the choice, the same can be said about the presence or absence of lining, the installation of rubber rings.

The rollers are mounted with a step of 10-15 meters on the middle part of the device, as well as where damage to the edges of the tape may occur as a result of its descent to the side. Some design options help cushion impacts at loading points.
