Flat belt pulleys
With over 100 years of experience in the design and
manufacture of belt drives, we are a powerful partner for your drive solutions.
We manufacture individual flat belt pulleys in all common profiles up to a
diameter of 2,500 mm.
Flat belt pulleys are important and versatile drive
element in many areas. Flat belt drives have clear advantages, especially in
cases where the drives that are subject to shock loads, and which are also
subject to vibration. The discs are very economical and highly reliable.
In order to meet the performance requirements of our
customers, all of our drives are individually designed. Weight, moment of
inertia, geometry and performance parameters are perfectly matched to the
requirements. Due to our flexible semi-automatic molding process, there are no
model costs for the initial production. Similarly, there are no costs for any geometry
adjustments before the moulding process. This flexible process enables the most
economical production and guarantees minimum delivery times with maximum
responsiveness.
Flat belt
pulleys are usually designed with a cylindrical bore. In the case of higher
power transmissions, it is also possible to work with clamping sets thanks to a
reinforced hub design. Alternatively, all flat pulleys can also be manufactured
as a TaperLock version (TL).
The drives
can be manufactured quickly and extremely flexibly even in the event of
changes. The batch size of 1 piece for urgent spare parts or prototypes as well
as series are not a problem.
