MDU micro-metering unit

See Figure 5
The MDU should be installed in a freely acces-
sible area so that subsequent adjustments can
be made and to ensure good visibility for the
LEDs.
The MDU can be mounted in any position.
SKF recommends installing the micro-meter-
ing unit in such a way that the capillary line
connections point in the direction of the lubri-
cation points and are as short as possible
(max. length of 4 m).
Due to its protection class of IP67, the MDU
cannot be mounted on the spindle/spindle's
working area. Any cooling lubricant that dis-
charges does not impair function.
Any assembly holes must be made according
to the Figure 5 below.
During assembly and especially when drilling,
always pay attention to the following:
o Existing supply lines must not be damaged
by assembly work.
o Other units must not be damaged by
assembly work.
o The MDU micro-metering unit must not be
installed within range of moving parts.
o The MDU micro-metering unit must be
installed an adequate distance from
sources of heat.
o Maintain safety clearances and comply with
local regulations for assembly and accident
prevention.
To ensure enough space for maintenance work
and for possible disassembly of the SKF mi-
crodosage system, ensure that the minimum
mounting dimensions (Fig. 5 and Fig. 6) are
maintained.
Assembly instructions
4.4.1 Attachment of the MDU micro-
metering unit
See Figures 5 and 6
Attachment of the micro-metering unit
• Drill assembly holes (Ø 6 mm) (1) on the
surface provided by the customer according
to the assembly drawing (Fig. 5).
• Clean surface to remove drilling chips;
prime the boreholes if necessary.
• Pass hexagon head screws (2x) with
washers through the fixing holes on the
mounting position/mounting plate.
• Apply hexagon nuts (2x) with washers on
the MDU and tighten gently; align the MDU
horizontally and vertically.
• Tighten hexagon head screws.
Electrical connection
• Place plug and socket coupling (M12x1)
onto the connector plug (2) of the MDU,
then align and tighten by hand.
