Brush holder - Import export

Quality level and design as per customs specifications. Also available : brushes with wear signalling wire.

Our flange holders can be fitted either directly into the machine housing or on brush rockers. What can we offer you? MACK flange holders offer a space-saving and inexpensive option for contacting carbon brushes to a collector. The spring pressure on the carbon brush comes either from a coil spring or a rocker. We can realise connection options for you using very different thread and plug connections.

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.

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.

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.

Slip rings provide the basis for rotating current transfer and all its demanding applications. Which challenges can we meet for you? In combination with our slip rings, brush holders fitted with carbon brushes ensure that the current to be transferred is collected. Thanks to their increased vibration resistance, solid-cast slip rings can withstand high mechanical and electrical loads. These are available from MACK in many different versions, many of which are even available from stock.
