DIN 7753 Part 1 / ISO 4184, SPZ, SPA, SPB, SPC

Product description
Drive belts with cable cord, consisting of rubber coating, base compound and cover fabric

Application examples
Version 1:
Model for machines from countries which use this profile, e.g. USA, Canada. Heavy drives (8 V), e.g. mill works for the transfer of high power.

Version 2:
Model for low-burden drives, e.g. rotary pumps, up to high-burden machines, e.g. stone crushers

Product description
The Strongbelt kraftband consists of V-belts of the same length which are connected with each other through a top surface. This compact drive product with single belt characteristic is also called the joined V-belt. According to their use, kraftbands are equipped with two, three, four or five ribs. If necessary, kraftbands with more than five ribs are available. It is also possible to equip the top surface with special top surfaces.

Areas of application
Kraftbands are successfully used in mechanical engineering, e.g. on filter vibrators, gang saws, stone crushers, road construction machines, compressors, fans, turning lathes, grinding machines and milling machines.
In agricultural machines, Strongbelt kraftbands are also required as clutch belts. The single belt characteristic guarantees good engagement and release.

For transport tasks, Strongbelt kraftbands can be equipped with an additional top surface.

With profiled top surfaces, they are suitable for the transport of containers and heavy loads, e.g. when loading aircraft.

Ribbed belts


Product description
V-shaped, ribs arranged in parallel made of a rubber mixture which is resistant to wear form the carcase. The high-quality and extremely low-stretch polyester tension cord is embedded in a rubber mixture and stretches along the entire width of the ribbed belt. The outer surface, tension cord and carcase are connected to each other by means of vulcanization.

Areas of application
Whereas the profiles PJ, PK, PL and PM are used in general mechanical engineering, the profile PH is used primarily in the field of household appliances. The profile PK is used mainly in the automotive industry.

Chloroprene timing belts

MXL, XL, L, H, XH, XXH, 2M, 3M, 5M, 8M, 14M, S3M, S4,5M, S5M, S8M

Product description
Timing belts made of chloroprene with fibreglass tension cord, shear-resistant teeth and protective fabric for running surfaces

Areas of application
For drives which require a constant speed transfer. For drives which should be as maintenance-free as possible.
For high precision milling and grinding machines, office machines, household machines, for drives in precision engineering, control and operation technology.

V-grooved pulleys for taper bushes

Grooves acc. to DIN 2211

Product description
V-grooved pulleys form an essential component of a V-belt drive. They are made mainly of cast iron GG20 according to DIN 1691 and used with pilot holes, finished holes or with a taper bush system.

Areas of application
e.g. fans, compressors, centrifuges

Timing belt pulleys

for cylindrical drilling

Product description
Standard timing pulleys are drilled in advance and if desired can be completely drilled and grooved. As an alternative to this version, a model is available with conical holes for the use with taper bushes. According to the model, the materials are steel, grey cast iron and aluminium.

Areas of application
e.g. high precision CNC machines, textile machines
