charges. Stainless steel tubing is recommended to achieve sufficient
equipotential bonding.
All components of the lubrication line system such as pipes, hoses,
shutoff valves, directional control valves, fittings, etc. must be care-
fully cleaned before assembly. No seals in the lubrication line sys-
tem should protrude inwards in a way that disrupts the flow of the
lubricant and could allow contaminants to enter the lubrication line
system.
Lubrication lines should always be arranged so that air pockets can-
not form anywhere. Avoid changes in the cross-section of the lubri-
cation line from small to large cross-sections in the direction of flow
of the lubricant. When the cross-section does change, the transition
should be gentle.
The flow of lubricant in the lubrication lines should not be impeded
by the incorporation of sharp bends, angle valves, or flap valves.
Unavoidable changes in the cross-section in lubrication lines must
have smooth transitions. Sudden changes of direction should be
avoided if possible.
6.9 Lubrication line connection
The lubrication line must be connected to the lubrication unit in such
a way that no forces can be transferred to the assembled lubrication
unit (stress-free connection).
The fittings used to connect the lubrication line should be rated for
the maximum operating pressure of the lubrication unit.
For operating pressures up to 45 bar as can occur especially in
single-line piston distributor systems, SKF fittings for solderless pipe
unions can be used (double tapered sleeves or tapered sleeves). For
higher operating pressures up to 250 bar as can occur especially
in progressive centralized lubrication systems, SKF cutting-sleeve
screw unions conforming to DIN 2353 can be used. If using fittings
from other manufacturers, pay careful attention to the assembly in-
structions and technical specifications provided by the manufacturer.
WARNING
Environmental pollution
Lubrication lines must always be free of leaks. Lubricants
can contaminate soil and waterways. Lubricants must be
used and disposed of properly. Observe the local regula-
tions and laws regarding the disposal of lubricants.
6.10 Note on the rating plate
)
See Figure 19
The rating plate provides important data such as the type designa-
tion, order number, barcode, and serial number.
To avoid loss of this data in case a rating plate becomes illegible,
these characteristics should be entered in Figure 20.
