Buffer and support ring rollers fmg-sketch-green-1

What is the difference between buffer and backup ring rollers?


The FMG buffer and support ring rollers are characterized by optimal properties for your belt system in the bulk goods sector. With them, the transport of granular or powdery substances is effortless and your conveyor belt is cleaned at the same time. It should be noted that both product variants have different purposes, depending on the selection of the roll composition with buffer and support rings as well as security elements.

Buffer and support rings can be mounted as additional components on any roller in the FMG product range in order to be able to meet various challenges in the bulk goods sector. They differ greatly in their intended use.

Buffer ring rollers are ideal for protecting your conveyor system from damage caused by falling granular material such as cement or gravel. The soft elements effectively cushion the material and thus protect the service life of your system. They are often used at the material loading points, as this is where the conveyor belt is exposed to the greatest forces due to falling materials. The conveyor rollers are often filled over the entire roller width, but in addition to standard variants, we also offer individual solutions for your needs.

The use of support ring rollers, on the other hand, supports the return of the conveyor belt. They trickle off excess buildup and have a cleaning effect that protects your conveyor system in the long term. Furthermore, wear and tear on the actual roller is prevented and the associated costs are reduced.

Our buffer and support ring rollers are available in a wide variety of designs and thus ensure a flexible, individual and effortless way of working. Standard variants of the buffer ring rollers
differ in the number of mounted buffer elements, depending on the load and the weight of your transported materials as well as the securing of individual links against slipping sideways. Clamping and welding rings can be used to ensure stabilization from the outside. Depending on the individual nature of your conveyor system, we also offer you unsecured elements. Support ring rollers, on the other hand, are available in different versions with support rings of form A and B as well as buffer rings pushed in between. If necessary, further safeguards can be added between the support rings in the form of spacer sleeves.

The two product variants do not differ in quality. Her FMG Förderelemente Mecklenburg GmbH from Körchow uses high-quality rubber elements with a hardness of 70° Shore in production. Support rings can also be made from a wear-resistant but more expensive polyurethane with a hardness of 85° Shore, depending on their intended use. We are pleased to be able to offer you tailor-made solutions so that you can get the best possible benefit from our FMG buffer and support ring rollers for your conveyor system.

Do you need standard variants or buffer and support ring rollers individually tailored to your conveyor system? We would be happy to advise you on the entire product portfolio and answer any further questions you may have.


How does a larger diameter of the drive drum affect the conveying speed?

Different drum diameters enable the conveying speed to be better adapted to the needs of the system. Due to the physical laws of the drive drum, a change in the drum diameter is directly transferred to the conveying speed. Thus, a faster rotation of the drum results in a higher speed of the conveyor belt. A larger diameter offers additional support for these effects. The increase in…

How can a drum be overwound?

Drive and tail pulleys are essential components in a conveyor system and must ensure high performance and efficiency. However, over time, due to wear and tear or other influences, problems such as deformation or irregularities in the concentricity of the drum can arise. This can result in reduced performance and even damage to the conveyor. Therefore, a…

How can drive and tail pulleys be coated and why are there smooth and rough surface coatings?

Drive and tail pulleys are important components in a conveyor system that make a significant contribution to the performance and efficiency of the system. To ensure that the conveyed goods are picked up and transported in the best possible way, the surface coatings of the drums play a crucial role. Like most idlers, drive and tail pulleys can be painted, galvanized or coated with sheet rubber or Baytec. ...
