V-belts

Types and profiles of our V-belts:

Traditional encased V-belts

This V-belt is the most well-known of the drive belts. It consists of a rubber core with an embedded polyester tension member, a rubber top layer and an abrasion-resistant fabric casing. It is mainly used in industry, in mechanical engineering, washing machines, pumps, presses, etc.

Narrow V-belts

to DIN 7753/ in profiles SPZ 9,5/8; SPA 12,5/10; SPB 16/13,5; S19, SPC 22/18

to ISO R 460 in profiles 3V 9,5/8; 5V 16/13,5; 8V 25/22

Compared to traditional V-belts narrow V-belts have a higher performance with the same profile width.

Raw-edged, cogged, high performance narrow V-belts

PowerTwistplus® double V-belts in profiles AA, BB and CC

Reverse idler belts

Specially developed V-belts with an aramid tension member and black rubberised casing for applications with high impact loads or with reverse idlers in profiles 3L (3/8"), 4L (1/2"), 5L (5/8"), SA (13/7), SB (17/9)

Coupling belts

Specially developed V-belts for coupling drives with a grey, non-rubberised casing, an aramid tension member and optimum friction in profiles 3L (3/8"), 4L (1/2"), 5L (5/8")

Wide angle V-belts 60° flank angle

in profiles 3M, 5M, 7M, 11M made of polyurethane for high-speed drives with belt speeds up to 60 m/s. Polished edges and the enlarged flank angle of 60° provide an extremely low-vibration running behaviour. Small pulley diameters and higher belt speeds enable the construction of more compact and lightweight drives - including horizontal drives. These belts are also available as composite wide angle belts (without profile 3M). Outer lengths depending on profile from 180 mm to 2300 mm.

Wide V-belts or variator belts

to DIN 7719 / ISO 1604 raw edged, cogged, profiles: 13/5; 13/6; 20/10; 21/6; 22/8; 22/11; 23/10; 24/10; 25/8; 26/8; 28/8; 30/10; 32/10; 36/13; 37/10; 39/16; 40/13; 41/13; 47/13; 50/11; 50/13; 51/16; 52/16; 55/16; 62/22; 70/18; 70/22; 75/18; 76/17; 16W; 20W; 25W, 31,5W; 40W; 50W; 65/20; 83,1/25,1; 104,7/31or

to US standard RMA/MPTA raw edged, cogged (while stocks last) in profiles with the designation e.g. 1422 V 235

• high power transmission
• flexibility in running direction
• smooth running
• high transverse rigidity
• resistant to abrasion and slip
• long service life

Double V-belts

Profiles AA/HAA 13 x 10, BB/HBB 17 x 13, CC/HCC 22 x 17. The tension member is arranged at the centre of the profile, making the double V-belts extremely flexible and low-stretch. As the tension member is rarely subjected to pressure loads because of the special shape of the double V-belt, compared with normal V-belts, this belt is ideal for serpentine arrangements.

Further information about our V-belts:

V-belts are either encased or raw-edged. Essentially, they differ in their profiles, in other words their height-to-width ratio, then in the materials used and in the construction and material of the tension members. Normal standard versions are oil-resistant under certain conditions and heat-resistant up to approx. 70°C ambient temperature. Special versions (with minimum purchase quantities) are also available, of course:

• electrically conductive V-belts with approval certificate
• extra heat-resistant V-belts, ambient temperature 70°C - 100°C
• extra oil-resistant V-belts
• extra cold-resistant V-belts
• selected smooth-running V-belts

In multi-groove pulleys, we recommend using set-constant belts, which should be re-tensioned after a short running time. It is worth checking the pre-tensioning using a frequency meter, a tensiometer or a Krikit tension gauge.

Today's drive systems place high demands on V-belts. Until the late 18^th century, the simplest transmission elements such as ropes or flat belts were made of chrome leather. The industrial revolution, the invention of mastication and the vulcanisation of rubber (in the first half of the 19^th century), development of the first electric generator - all these achievements made possible an improvement in the quality of the original flat belts and established further applications in drive technology. Continuous improvements eventually led to the invention of the first V-belt, which was patented by John Gates in 1917.

Of fundamental importance for the operating characteristics of the various belts are the producers' manufacturing processes and manufacturing technologies. We are the Swiss representatives for ContiTech Antriebssysteme GmbH (www.contitech.de), SWR Europe-van Dinther GmbH (www.swr-europe.de), Gates GmbH and Bando Europe GmbH (www.bando.de). We also work with several European and Asian suppliers, who supply us with some well-known branded products.

The development of modern V-belts has to take into consideration the stringent requirements of a wide range of drive systems. Ever greater power transmission, longer service life even in the harshest of environments and in ever narrower spatial conditions, greater smoothness, a low price - meanwhile there is a drive belt for almost every requirement.
