Conveyor roller. Conveyor rollers - GOST

The roller is an important part for any conveyor belt. Its reliability and quality in many ways determine how well the machine will work, whether it can 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 design does its job and could last as long as possible.

What do we pay attention to in the first place?

Usually, the technical and procurement 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-related issues. For others, a more sensible and far-sighted approach is more important, then they are already looking at how the performance indicators relate to each other, pay attention to future conditions. Below, we will present information that is likely to be useful for such enterprises.

Modern production and its features

Each manufacturer can vary the ratio between cost and assembly. This is because everyone tries to please the individual requirements of any customer who seeks help. Conveyor roller for today is issued in 160 standard sizes. Each of them has its own characteristics, advantages and disadvantages. There is also a special, cushioning variety. It is best to choose the manufacturer that really pays attention to quality by releasing conveyor rollers. GOST is better still to comply.

About different modifications

Now the rollers can be a combined and non-assembled design. But there are not so many businesses that can produce just these two options.

Less weight - perhaps, the main characteristic, if a conveyor roller of a non-selective type is purchased. Such structures, if necessary, are easily replaced and transported, they weigh a 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 become indispensable, for example, if such types of parts are used as consumables at the enterprise. Despite the low price, non-rollers remain reliable enough.

In continuous-type plants, they can be successfully used when the conditions of repair and maintenance are severely hampered, in environments with aggressive impact. In such an environment, the conveyor roller rusts faster than the wear of the bearing.

Available alternative

Collapsible construction will be the most optimal option for enterprises where repairs do not cause any problems. Such a product can be re-installed on the unit after all maintenance work has been performed. The hub is attached to the pipe for welding along the entire length of the circumference . Thanks to this, the connection becomes very reliable and stiff. The service life increases, even a few cycles do not become a problem for this kind of products.

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

Important quality criteria

Convenience in operation, durability and reliability - perhaps the main requirements that are imposed on any quality products, including in this direction. Therefore, it is worth choosing for close cooperation only those enterprises that are able to meet these requirements. In many cities today produce a roller conveyor. Kemerovo is no exception.

Additional requirements

In addition, attention should be paid to the fact that the bearing itself is reliably protected from dirt and dust from getting on the outside, scale from the inside. The closed bearing of the 80th series is used to solve this problem in a non-collapsible design. The rubber seal provides additional protection when such conveyor rollers are manufactured. The price remains quite affordable. The cost of the videos depends on their size and the manufacturer and starts from about 150 rubles.

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

A little about wear and tear

Conveyor technology develops and changes as these processes occur in the direction of turnover and production. There are more and more new materials, methods of delivery of goods.

The conveyor itself has become quite widespread. At the same time, such equipment is one of the most expensive. And transport rollers wear out pretty quickly. It is necessary to establish additional details so that the production process does not stop.

About technical characteristics according to the state standard

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

The length can reach two thousand mm.

The shape of the product of this group is most like a cylinder. There is a special labyrinth seal to prevent dust from entering inside. Concerning the ends of the axes, the customer himself makes a choice, the same can be said about the presence or absence of lining, the installation of rubber rings.

Rollers are mounted in steps of 10-15 meters on the middle part of the apparatus, as well as where the edges of the tape may be damaged as a result of its descent to the side. Some design options allow you to mitigate impacts in the loading areas.
