    mbeltPower Transmission for perfectionists The bearer of performance

    = mbelt V-Belts

    These are your Advantages:+ Closest tolerances unrestricted

    use in matched sets+ Energy saving operation

    + Reduced vibration + Extended maintenance intervals + Longer belt life

    Mbelt S=C plus and Mbelt Super TX M=S two ways to reach one goal.

    Two completely different constructions: the one wrapped, individually made, piece by piece vulcanised in rotation with a know-how which has continuously been improved for many years. Raw Edged the other, representing a new generation.

    Nevertheless, they have very much in common.Both belt types are being used in the general machine building industry and both are made for optimum performance of users. They are the champions in their range.

    Mbelt S=C plus Power Transmission for perfectionists

    Twenty years of continuous development have made a V-Belt which cannot be more precise. The expression S=C plus has become a synonym for absolute use in matched sets. Machines of every kind are equipped worldwide with Mbelt S=C plus, in every location where specific requirements are demanded.

    Why this is so is shown by the following tolerance list.

    > 1200 2000 2 1 % 12,5 to 20 mm> 2000 5000 2 1 % 20 to 50 mm> 5000 8000 4 1 % 50 to 80 mm> 8000 10000 6 1 % 80 to 100 mm

    Mbelt Super TX M=S the bearer of performance

    The Super TX M=S is unrestrictedly usable in matched sets, too. An efficiency of 97 % allows high transmission of power. Like for the S=C plus the highly precise manufacturing process and the matured material technology provide for closest tolerances. The Mbelt Super TX M=S meets all valid standards worldwide for V-Belt sets.

    The extremely positive ratio between standard and Mbelt tolerances is also applicable to these sections.Please take exact data from our technical literature.

    General IntroductionAll Mbelt V-Belts are manufactured with carefully chosen raw materials utilising continually updated manufacturing me-thods.The modernisation of production proces-ses, large scale laboratory testing, and the careful control of the basic materials will guarantee a consistent quality for every Mbelt power transmission component. Product function, efficiency and durability are of major importance to Mbelt.

    CharacteristicsOil resistantThe oil resistant cover of the belt protects it from contamination by mineral oil/ grea-se splash. Contamination by animal or vegetable oil or water solvent cutting oil will reduce belt life. In extreme cases the use of special construction XOR is re-commended.

    Heat resistantStandard construction Mbelts will ope rate in ambient temperatures up to + 70 C/ +158 F.Higher ambient temperatures will lead to premature ageing and subsequent belt failure. In this case our special construc-tion XHR is recommended.

    Cold resistantStandard construction Mbelt V-Belts will perform satisfactorily in ambient tem-peratures down to - 40 C / - 40 F for wrapped construction and - 30 C / - 22 F for raw edge construction. Under critical conditions practical tests are necessary.

    Anti staticIn order to comply with product safety requirements the specific Anti Static pro-perties of any V-Belts must be tested to ISO 1813. A test certificate will be issued and a 20% surcharge will be applied. Anti Static V-Belts should be specified separately to ensure that the correct certi-fication is carried out (EN 10204 3.1.B).

    Special ConstructionsThe following are examples of surcharges applicable to special construction.

    Smooth running - LR 20%Extra oil resistant - XOR 20%Extra heat resistant - XHR 20%V-Belts with Patterned Top Surface - PKR 200%

    Prices for other constructions on request. Observance of special tolerances will be charged according to actual cost.

    Non standard Lengths and Special Constructions for Wrapped V-BeltsIn the event that fewer production sets than normal are required for a particular special construction wrapped belt (nor-mal-3 production sets) then the following surcharges apply:

    2 production sets 20 % surcharge 1 production set 40 % surcharge Please note that minimum production set quantities may vary for certain special construction belts. If in doubt ask your Mbelt contact.

    Multiple Belt DrivesRequirements for drives using sets of belts often demand belt measurement to form the sets. Mbelt S=C plus and Mbelt M=S belts do not require belt measurement or re-measurement to form sets.
