Information on assembly

The assembly procedure for the SKF micro-
dosage system is described in detail in the as-
sembly instructions (Chapter 4) associated
with these operating instructions.
4.2

Installation and use on spindles

General
The microdosage system can be used for con-
tinuous and highly accurate metering of small
quantities of lubricant.
The following points must be observed when
designing the spindles and selecting the bear-
ings so that the extremely small quantities of
lubricant can reliably reach the lubrication
points.

4.2.1 Spindle design

See Figures 1 to 3
The microdosage system and its lubricant out-
lets were designed for capillary lines with an
outside diameter of 1/16 inches and an internal
diameter of 0.5 mm.
The tube threads indicated in Figure 1 are
suitable for connecting the capillary lines on
the spindle and bearing.
The capillary lines are connected similar to the
capillary lines on the microdosage unit
(see page 28, Fig. 7).
The required connector systems (socket
unions, ferrules, clamp rings) can be ordered
separately as accessories (see Chapter 11).
The maximum length of capillary lines be-
tween an outlet on the micro-metering unit
and the lubrication point is 4 meters.
