Slip rings - When it’s mechanical and electrical

Tried and trusted standard types, or individually produced special solutions: No matter what you require – we have the right grade for any application. High quality and individually produced. Brush grades describe the exact composition and the quality of our carbon brushes. With a wide range of formulations and properties, we ensure that the correct carbon brushes are supplied, even for the most special customer requirements. Thanks to special reworking processes such as impregnation, we can alter and improve the properties of MACK brush grades. For example, we can provide increased strength, improved slide characteristics, or lower spark production. MACK carbon brushes are divided into five grade categories: Carbon graphite grades Our graphite carbon grades consist of different types of graphite.

The classic solution for many slip ring applications: At MACK you will find the right leg brush holder for your technical requirements. Without any doubts. Our tried and trusted holder model is available with one or two legs, with fixed or adjustable carbon brushes, in metal or – as a special version – in plastic. Together we can develop the individual version that meets your requirements. As with most MACK products: We do everything ourselves, and only in our own facilities – from the production of the main parts to the completion of all assembly work. This is how we can guarantee you maximum precision and process security.

MACK brush holders with clamps are available in many different sizes, shapes, versions, and materials – also for your slip ring or commutator application. Our brush holders with clamps have everything tightly under control. The carbon brushes are inserted into the brush shafts of the holder. The brush pressure comes – depending on the type – from a pressure finger, or (in the case of a self-recoiling spring holder) with a suitable self-recoiling spring holder, which permits the use of above-average length carbon brushes.

Our insulated brush-holder bolts provide the mounting basis for most leg brush holders and brush holders with clamps. What fits your design? At MACK, we always go into things in depth and talk about the details. We fit our holders on insulated brush-holder bolts, which can be produced individually to special measurements.
