Holders, telescopic-holders and inserts for electromagnetic clutches.
We have a large stock of holders and replacement brushes. The inserts are made of copper graphite when used for dry application or of special metal mesh for application in oil.
You will also find the most common types of ZF telescopic holders and inserts in stock.
Thanks to our large inventory of brush holders and inserts, we can provide you with all common products of this kind and a large selection of ZF types in the earliest time: Most of them can be shipped the same day!
Various combinations are possible for the clutches:
Holders and inserts (standard types)
High-quality holders and inserts for tough everyday industrial life.
Holders and inserts (telescopic types)
While for dry applications one holder per slipring is sufficient, it is different with in-oil applications. In that case, there is a constant risk that the sliprings get in contact with too much oil. This oil film then interrupts the power supply, which understandably has serious negative consequences.
To avoid this susceptibility to failure, two holders should be installed one behind the other at a rotation speed of more than 18m / s. Additionally, it is important that the holders are attached in a way that they are free of vibrations.
Also, in order to achieve the desired brush pressure, a minimum distance of mostly two millimeters should be maintained between the installed brush holder insert and the slipring.
Of course, the specialist staff of D.E. Marl Industrievertretungen will be happy to advise you in detail so that you receive the optimal power supply for your application.
