A 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 design really fulfills its purpose and can last as long as possible.
What do we pay attention to first of all?
Typically, technical and procurement policies become the main factors on the basis of which this or that type of equipment is purchased. The same can be said for conveyor rollers. In some cases, they prefer cheaper models and options, not paying attention to issues related to quality. For others, a more reasonable and far-sighted approach is more important, then they already look at how performance indicators relate to each other, pay attention to future conditions. Below you will find information that is likely to be useful specifically for such enterprises.
Modern production and its features
Each manufacturer can vary the ratio between cost and assembly. This is because everyone is trying to cater to the individual requirements of any customer who seeks 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, releasing conveyor rollers. It is better to comply with GOST.
About different modifications
Now the rollers can be prefabricated and non-prefabricated. But there are not many enterprises that can produce these two options at once.
Lighter weight is perhaps the main characteristic if a non-demountable conveyor roller is purchased. Such structures, if necessary, are easily replaced and transported; they are lightweight and relatively cheap. This product is quite simple, but there is only one drawback - you can use it only once. However, it can become indispensable, for example, if at the enterprise such types of parts are used as consumables. Despite the low price, non-separable rollers remain reliable enough.
In the continuous type of production, they can find successful application when the repair and maintenance conditions are very difficult, in environments with aggressive effects. In such an environment, the conveyor roller rusts faster than bearing wear occurs.
Affordable Alternative
The collapsible design will be the best option for enterprises where there are no problems with the repair. Such a product can be reinstalled on the unit after all maintenance work has been completed. 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 a few 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 assembly remains the same in any case, any conveyor rollers fall under this rule. The production of each group provides only differences in the type of bearings. In the heavy series, the bearings are more powerful, so that 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
Convenience in operation, durability and reliability are perhaps the main requirements that apply to any quality product, including in this direction. Therefore, it is worth choosing for close cooperation only those enterprises that are able to meet these requirements. Many cities today produce a conveyor roller. Kemerovo is no exception.
Additional requirements
Among other things, attention should be paid to ensuring that the bearing itself is reliably protected from ingress of dirt and dust from the outside, and scale from the inside. The 80th series sealed bearing is used to solve this problem in a non-separable design. A rubber seal provides added protection when such conveyor rollers are available. The price remains quite affordable. The cost of the rollers depends on their size and manufacturer and starts from about 150 rubles.
If a collapsible variety is purchased, then the bearing is protected using a special cap from the inside, a double labyrinth seal. The simultaneous boring of the pipe from two sides must be carried out in order to avoid the beating of the roller, which puts the mechanism out of order.
A little bit about wear
Conveyor technology develops and changes as these same processes occur 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 transport rollers wear out pretty quickly. You have to install additional parts so that the production process does not stop.
About technical specifications in accordance with GOST
According to these documents, the diameter of the conveyor rollers is from 89 to 159 millimeters.
Length can reach two thousand mm.
In shape, the products of this group most resemble a cylinder. There is a special labyrinth seal to prevent dust from entering. Regarding the axle ends, the customer himself makes the choice, the same can be said about the presence or absence of the lining, the installation of rubber rings.
The rollers are mounted in increments of 10-15 meters on the middle part of the apparatus, 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 can mitigate impacts at loading points.
