Telescopic Slipring Brushes

We stock an array of slipring brushes as used to operate electromagnetic slipring clutches. They are available in telescopic types with M14, M16 & M18 threads in varied lengths to suit all clutch manufacturers. We also stock caliper type. A selection of types we keep are EMS, SK4, TSN, TSK, TSL, EMS 2A, EMS 2A/40, EMS 2A/60, EMS 22 mm, Tourco caliper type.

General information:

The above brushes are suitable for ''wet application'' (runs in oil) and can be used in a 24 volt DC supply. They are designed to give good transfer of electrical supply to the clutch slipring despite the presence of an oil film. To ensure satisfactory power supply to the clutch, the special ''wire type brush'' insert should be pressure loaded enabling it to penetrate the oil film and give a good contact.

If this is not achieved, burning of the slipring is imminent, resulting in the clutch being rendered non functional.

Brush construction:

The telescopic brush is made up of a screw body of the size stated in each type. The brush insert is so designed that its construction has an inner & outer brush, performing a good wiping action & ensuring a good contact. Secondly the outer and inner brush are designed to have different natural frequencies in order to ensure this good contact in the presence of vibration, because only one brush at a time can be in resonance, resulting in a prolonged brush life.
