Easier installation and dismantling
In many cases the whole drive with all components needs to be
elaborately dismantled and afterwards reinstalled when exchanging or replacing
drive pulleys. To simplify this process we offer divided pulleys which can be
disassembled in two halves and perfectly put together again at the shaft.
We produce all sorts of divided pulleys (v-belt pulleys, flat belt pulleys, band wheels etc.) as exclusive custom-made products. Depending on the
requirement the pulley will be implemented as arm or base pulley.
All geometries can be easily produced in a flexible, model-free moulding process. Divided pulleys are produced from batch sizes larger than 1 piece for urgently
needed spare parts , prototypes, zero-series models or series according to individual
requests or drawings.
In close cooperation with the customer we develop the optimal solution
for individual drives.
For the production of divided pulleys we already separate the raw
casting – using the predetermined breaking points – just to reassemble and fix
it immediately afterwards. The gray cast structure, which almost didn´t deform
elastically before the fracture, is used to achieve a perfect fit at the
breakpoint for seamless reassembling.
The experience over many years of casting with predetermined breaking
points, blasting and subsequent mechanical treatment of the divided pulleys makes
a customized highbrow drive unit.

- Arm or base
- By default divided
pulleys are balanced in grade G16, G6.3 or G2.5
- All surfaces are
grounded to avoid corrosion, processed functional surfaces are conserved with
spray wax / oil
- Individual surfaces and special varnishes as well as corrosion protection are possible
according to individual specifications
- Upon request we offer
detailed documentation to prove material properties, balancing qualities and
products according to individual customer specifications or drawings
- Support with drive
set up, control, recalculation and optimization
- Pulley geometries
are optimally adjusted to the corresponding drive situation
- If required full
transparency due to approval drawings prior to production start or for detailed
- Flexible moulding
