FMG Förderelemente Mecklenburg GmbH was founded in 1991 and is a company specialised in the manufacture and distribution of components for conveyor and product storage technology. Whether for machinery and system constructors or system operator of all industry sectors in all parts of Europe:
Due to the high degree of vertical integration of the inhouse production, tailor-made solutions for all needs are delivered with convincing flexibility and a consistently high product quality.
FMG develops and manufactures individual conveyor technology and storage technology elements, which are characterised by the high quality and long service life of the support rollers. Unique and pioneering products are created under consideration of the specific customer requirements.
The product portfolio includes both standard rollers, which are manufactured in accordance with the corresponding DIN standard as well as special orders for customer-specific requirements and area of application.
FMG support rollers are essentially comprised of three components: the bearing, the pipe and the axle. LFD bearings are designed optimally for the requirements of the conveyor technology and logistics sector. Detailed specifications on these individual components are required for the construction of a support roller with the respective length dimensions in accordance with the customer’s specifications.
Due to the specified order nomenclature in the detailed FMG catalogue and the online configuration software, which can be loaded and used on the manufacturer’s homepage, it is possible to describe an accurately delimited support roller.
This is supplemented with the precise designation of the type range of the matching LFD bearings. This applies to both driven as well as non-driven rollers. On its own homepage www.LFD.eu, LFD offers a complete database.
The company supports customers with advice as many points must already be observed during the construction.
In the framework of the construction, the following is advisable...
Generally, LFD deep groove ball bearings are the safe choice. When more inexpensive LFD deep groove ball bearings are used in lieu of LFD spherical roller bearings in borderline cases with particularly heavy goods, it should always be examined precisely whether the installed ball bearings are suitable in regard to design, performance and load in the respective application.
As is known, different bearings also fit in the different housings. When rollers have a deflection capacity, then the reliable radial load capacity of the deep groove ball bearings or spherical roller bearings is a deciding factor.
LFD ensures these requirements with its own laboratory equipment and test benches. Nevertheless, spherical roller bearings are more flexible than deep groove ball bearings. Therefore, in the event of especially heavy loads, a consensus must be reached on what the respective bearing must be able to absorb and by which factor the axle may deflect.
Here, spherical roller bearings are able to absorb significantly larger deflections without damage being inflicted on the conveyor line.
For average loads, usually the LFD Standard deep groove ball bearings are the right choice, both for cost reasons as well as for the goods to be conveyed and the durability of the conveyor elements.
LFD has implemented the labyrinth with the special inner race form in the so-called V groove. A friction seal can engage in the V-shaped recess or the contour of the sealing lip follows with the gap to the V groove. This non-friction variant, which is still very efficient is called the RZ seal. This is for example used in rollers of gravity conveyors in parcel distribution centres worldwide, on which even with only a slight incline, goods can be conveyed without the application of great force. RZ seals are useful in all applications in which performance losses due to seals are undesired and the expected degree of contamination is not significant.
A suitable powerful sealing system for the reliable and efficient use of the FMG rollers is offered for all areas of application. The product range is supplemented by plastic rings, support rings and buffer rings, which FMG equips the support rollers with according to the customer’s wishes before delivery. A large selection of different ring sizes and properties fulfils the entire range of the customer requirements.
Additional CNC lathes, automatic welding machines with corresponding extraction and welding power sources, automatic thread-cutting machines and steel washing machines enable an extensive vertical integration of manufacture during the production of the conveyor elements.
When no further details are provided in the catalogue or the online configurator of the company on the bearings or drives, then as standard, 2Z sealed deep groove ball bearings are installed.
When bearings or drives are to be produced in specific ball bearing qualities or the steel bearing holders or drives should be made of a material type other than steel, then this must be performed following the respective type range.
Other ball bearing qualities can be:
As standard, FMG support rollers are produced in various RAL colours, which are applied on-site using a two-component paint system. Of course additional coatings can be implemented in-house and in cooperation with specialist partner companies – e.g. electro-galvanizing or rubber coatings.
A process innovation was achieved in the framework of a device for the fitting of PVC hoses on steel conveyor rollers.
