2.1 MECHANICAL MOUNTING
To avoid subjecting the cells to vibration, the slip ring must be connected to the rotating part by a flexible
coupling. This will increase the lifespan of the slip ring’s cells.
There are two types of flexible couplings available:
• MK1/20/35/12H7/12H7 couplings are used in the standard UHS 2XX-011 with operating speeds of up to
20,000 tmin-1.
• MK1/20/35/12H7/12H7/HS couplings are used in the highest-speed UHS 2XX-111 with operating
speeds of up to 40,000 tmin-1.
The coupling is attached to the slip ring by the included clamping screws.
For proper mounting of the slip ring, use of the original fixture support is recommended (part number 198-102-
955-011). This support has a special coating which protects the slip ring housing and assures its electrical
insulation. Proper alignment of the slip ring is necessary to avoid vibration or side loads to the flexible
coupling.
In addition, at high rotation speeds the alignment of the slip ring must be very precise. For applications with
speeds up to 40000 tmin-1, it is advised to have a precision of alignment of about 0.05 mm.
The slip ring produces a small EMF at high-speeds. To avoid increasing the EMF it is necessary to prevent
the rotating part from overheating the slip ring. Increasing the EMF can cause the vaporization of mercury
within the cells.
To ensure a long lifetime, it is recommended that the ROTOCON UHS Brushless Slip Rings are operated only
within the specified temperature range.
