Siegling Extremultus – exceptional power tran***ission
We h***e developed the Siegling Extremultus power tran***ission belt range in close co-operation with users and OEMs. As a result, it can offer a market-driven range of types that can handle all sorts of power tran***ission in every industry.

Multi-purpose, highly-efficient belts Overview of the lines A, E, P line product range 5 6 8
Different materials for the friction and top coating are combined with one of the three tension member materials – A (aramide – also truly endless) – E (polyester – also truly endless) or – P (polyamide) Producing a varied range with ideal properties for each and every application. Siegling Extremultus power tran***ission belts are durable, extremely tough, elastic, absorb vibrati*** and shocks and can be used at belt velocities of up to 100 m/s.
Compared with other power tran***ission belts, they are easy to handle, extremely efficient and h***e a high level of synchronisation accuracy. Apart from traditional pulleys, they can easily handle bevel and cone drives and drive several shafts, even in different rotational directi***.

Multi-purpose, highly-efficient belts
In addition to other advantages, flat belts are much more efficient than V-belts. In V-belts, energy losses occur, not just due to flexing in the material, but also due to friction at the sides and other aspects associated with the belt design.
Friction on the sides at the top and bottom, internal friction losses due to hysteresis.
Higher friction losses when the V-belt pulleys are misaligned.

Elastomer G: 0.3 % – 1.0 %, urethane: 0.3 % – 0.8 % High flexibility Low Z-splice 110 x 11.5 mm without adhesives Power tran***ission belts with aramide tension members are designed for high levels of specific effective pull. Aramide line belts require careful handling to ensure perfect operation.
Other factors
Friction/top layer properties
Urethane (U) The urethane friction layer U is mainly used for drives. Thanks to its low thickness, it is especially well-suited for extreme flexing stress. Elastomer G (G) The friction coating elastomer G is used for all standard drives, also wherever dust and moisture are a factor. Not recommended when oil and grease are present (e.g. oil vapour). Chrome-leather (L) The chrome-leather friction coating is used wherever oil and grease are present.

Power tran***ission belts with truly endless polyester or aramide cord tension members require short take-up ranges, can tran***it high specific levels of effective pull and are not sensitive to fluctuati*** in ambient conditi***. Because they are very flexible and track very steadily and evenly, they are an excellent choice for high levels of power tran***ission (> 60 m/s) and multiple rotati***.
GG = elastomer friction layer on both sides (normal pattern) for power tran***ission on both sides UU = green urethane friction coating on both sides, power taken from both sides of belt. GT = elastomer friction coating on one side, for power tran***ission on one side, top coating made of polyamide fabric.
LT = chrome-leather friction coating on one side, for power tran***ission on one side, top coating made of polyamide fabric. LL = chrome-leather friction coating on both sides, for power tran***ission on both sides

Legend * The ***allest permissible pulley diameters were established in standard ambient conditi*** (23 °C, 50 % rel. humidity). Lower temperatures require larger drum diameters. For the P line, this also applies in the case of low humidity.

Special properties/resistances (all lines) Siegling Extremultus is antistatic. Truly endless types cannot be lengthened, shortened or repaired. The Siegling Extremultus GT and GG types are not sensitive to oils and greases, as well as commonly-***ailable solvents. However using in oily or greasy conditi*** (e.g. oil vapour) is not to be recommended (risk of the belt slipping – if possible use LT or LL types). The Siegling Extremultus sub-types LL, LT and UU are impervious to machine oils, diesel fuels, petrol, benzene, commercially ***ailable solvents such as ethyl acetate, acetone, etc.; chlorinated hydrocarb*** such as perchloroethylene, etc. Siegling Extremultus is not resistant to organic and inorganic acids. For further details, see the Siegling Extremultus – Technical information brochure (ref. no. 316).
