5 Products For more than 30 years A Zeta Goa, in the heart of the ceramic district of Sassuolo, has been an invaluable reference point for the most diverse productive sectors ranging from big industry to small businesses. This company, a European leader in the distribution of transmission belts, timing and thermo-weldable belts and all types of conveyor belts, stands out for its exceptional versatility and quick response service, with more than 60,000 items in stock, ensuring that every need can be promptly satisfied. The new facility, in Via Radici in Piano, extends across a covered surface area of ten thousand square metres. The company has grown steadily since it was founded in 1973, by strengthening its leadership in Italy, where it can count on more than 3,000 customers. Furthermore, it is in constant expansion paying increasing attention to overseas markets which today represent more than 20 % of its turnover. Its jewel in the crown and most prestigious business card is its own exclusive trademark M.E.C. V BELT which is now present all over the world.

6 M.E.C. V-Belt The modern M.E.C. V-BELT OIL STAT V-belts produced by A Zeta Goa stand out thanks to their excellent resistance and the high level of transmissible power. If we compare them to the famous flat belt, the level of adherence is tripled thanks to contact only being established along the tilted sides of the pulley races ensuring improved adherence. All M.E.C. V-BELT belts also feature OIL STAT. This means they are resistant to the action of oil and heat, they are electro-conductive, thus ensuring the electrostatic charges are deflected properly, and they are ISO 9000-compliant. Produced with last generation technology and subjected to stringent checks and tests, the M.E.C. V-BELT belts can be supplied upon request in customised lengths of up to 22,000 which are not present in our catalogue.

30 M.E.C. V-BELT OIL STAT (3-5 V) FTD BELTS with narrow section according to US standards with notched raw edges 3-5V-FTD belts are especially suited to heavy-duty conditions and with technical limits. Use of these belts is recoended when: A) pulleys have smaller diameters than the standard requires B) transmissions have a high number of revolutions C) there is a surplus of power requirements Belt sections Compliant with standards RMA/MPTA IP22 The Conventional M.E.C. V-BELT 3 and 5V FTD OIL STAT V-belts with narrow section according to US standards with notched raw edges are available in the sections indicated in the table below: Sections A S Angle 3 V V Belt identification The Conventional M.E.C. V-BELT OIL STAT 3 and 5V FTD V-belts are identified by a symbol consisting of a number followed by the letter V, which specifies the section (e.g. 3V ) and by another number (e.g. 800) which indicates the rated external in tenths of a inch. This symbol is printed along the back of the belt. Please consult the relevant Calculus Booklet for the technical characteristics. N.B.: The M.E.C. V-BELT OIL STAT 3 and 5V FTD belts (with notched raw edges) are the result of a highly advanced production system using blends of high quality rubber. The light weight of the belt reduces centrifugal force, thus providing greater speed; the forged notches afford greater flexibility, and consequently a higher frequency of flexure and faster heat dispersion (resistant to temperatures from -30 to + 80 C ) FTD: longer life compared to corresponding traditional values 28

45 M.E.C. SYNCHRONOUS TIMING BELT BELTS for industrial transmissions Notched belts, made with neoprene rubber and fibreglass inserts, are the latest innovation in the field of transmissions, whereby movement is transmitted from the pulley to the belt and vice versa by reciprocal meshing of the notches, as happens with gear transmission, with no slipping and precision timing. By virtue of their strength, these belts afford powerful transmission in limited space. Classification of the M.E.C. TIMING BELT belts The M.E.C. TIMING BELT belts are available in the following pitch distinguished by the coercial names shown to the side and the following standard widths: Coercial name Pitch Standard Widths inches inches (hundredths) MXL 2, ( 2 / 25 ) 3,05-4,80-6,35-7,90-9,40 0,12-0,19-0,25-0,31-0,37 XL 5, ( 1 / 5 ) 6,35-7,90-9,40 0,25-0,31-0,37 L 9, ( 3 / 8 ) 12,70-19,05-25,40 0,50-0, H 12, ( 1 / 2 ) 19,05-25,40-38,10-50,80-76,20 0, XH 22, ( 7 / 8 ) 50,80-76,20-101, XXH 31, ( 11 / 4 ) 50,80-76,20-101, Identification of the M.E.C. TIMING BELT belts The M.E.C. TIMING BELT belts are identified by letters which are preceded and followed by numbers which serve to identify pitch length, pitch and width respectively. The first number shows the value of the pitch length in tenths of an inch (hundredths of an inch for MXL). The letters show the pitch and hence the type of belt. The second number indicates the width in one hundredths of an inch. Example: A belt with a pitch of 60 inches (1524 ), pitch of 1/2 inch (12.7 ) and width of 3/4 inch (19.05 ) width, is written as follows: 600 H

58 M.E.C. SYNCHRONOUS TIMING BELT HTD for industrial transmissions HTD stands for High Torque Drive. The synchronous HTD belts are characterised by a new profile (rounded notched) which makes it possible to transmit more power with the same pitch as traditional synchronous notched belts. Furthermore, other advantages include the reduction of noise and interference, increased resistance against the notch being skipped and shearing stress, precise angular transmission and constant speed up to 50 mt/sec., low tensioning, excellent reliability, compact dimensions and moderate maintenance. STD MEANS SUITABLE FOR EXTREMELY HIGH TORQUE MOMENTS In addition to the advantage above indicated for HTD belts the following advantages are added: A) longer life thanks to the new profile edge and to a higher quality of the material used for the belt manufacture. B) resistant to temperatures between -20 and 100 C, resistant to atmospheric agents and moderately resistant to oil C) almost silent D) reduced maintenance requirements E) these belts permit the synchrony transmission, made in the past by means of chain, and therefore high power transmission with low revolution number.

90 M.E.C. POLYFLEXOSIL BELT To transmit more power in less space Made of polyurethane and with polyamide inserts. It is the idea belt for machine tools and for all the machines that require high speed and a perfect and regular smoothness in a limited space. Characteristics and advantages of the M.E.C. POLYFLEXOSIL BELT Exceptional abrasion resistance High modulus of compression High friction factor Better resistance to environmental agents Excellent resistance to fatigue Stability of tension Perfect smoothness without vibration at high speed Reduction of the width of the pulleys High transmission ratio Long working life of the pulleys with small diameter Wide field of use Reduction of the costs Section Code 3M 5M 7M 11M Belt sections Rated width The properties of the material The special blend of polyurethane has special physical properties which are significantly better compared to the most traditional materials usually used in the manufacturing of belts. As well as the excellent fatigue resistance and wear resistance, and the high friction factor, polyurethane also ensures excellent resistance to ozone, oxidation, heat and mineral oils. Polyurethane also allows adhesion on the strands to be improved as the belt is obtained by pressure die casting. The special ribbing The typical ribbing obtained by melting on the strands in polyamide ensures a higher transverse stiffness, without reducing the longitudinal bending capacity. The ribbing also helps heat dissipation of the belts during operation. The section and the angle The high friction factor given by the polyurethane, enables this belt to adopt the angle of 60. This typical angle allows better support of the strands in polyamide for traction and higher and more stable tension. This allows more power to be transmitted with smaller sections. NOTE: MEC BELT POLIFLEXOSIL MULTIPLE belts can also be supplied: we do not recoend however, using more than three elements. 88
