* The oil-mist lubrication and air-oil lubrication are similar regarding the functioning of spindle. So the
choice depends mainly on the machine on which the spindle is mounted.
!
ATTENTION!
Failure to observe the type of bearing lubrication can cause rapid damage
to the spindle.
Grease
For spindles of this type, there is no provision for external lubrication. The bearings are permanently
lubricated for the life time of the electric spindle. Air overpressure inside the spindle prevents the
infiltration of impurities.
The required quality of the air is given by: DIN ISO 8573.1:2001 Class 3.
The air pressure should be 0.6 to 0.7 bar at the entrance of the spindle.
!
ATTENTION!
A greater pressure can cause damage to the spindle.

Oil
Motorex COREX HLP ISO VG 32
Regulation of oil flow
30 drops per minute
Accessories included with the group
1 liter of Motorex COREX HLP ISO VG 32
Pneumatic tube
ø6/4, length 2m to 10m *
* The
first 10 cm of tube are ø4/2.5. The length of 10 cm should not be exceeded.
!
ATTENTION!
Without a right lubrication, the spindle will be damaged very fast. It is best
to use a coil at the proximity of spindle; to create an oil reserve in case of pressure is
disabled.
!
ATTENTION!
This kind of lubrication requires a stable and continuous in time functioning
to establish a steady oil flow in the tube. Thus, frequent interruptions of lubrication and air
pressure are not allowed. Lubrication must be active during periods of at least 1 hour.
!
ATTENTION!
O
nly one spindle can be connected to each oil mist lubricator. With multiple
connections, it is not possible to guarantee the quality or quantity of lubrication on each
spindle.
DLB-MHF lubricators are available with different options, defined with a suffix as follows:
- DLB-MHF: Basic version (with air filter and lubrication unit).
- DLB-MHF-C: Electronic monitoring of air pressure and oil level.
- DLB-MHF-CEVII: Electronic monitoring of air pressure and oil level, solenoid valve at the air inlet.
- DLB-MHF-AD: additional lubrication unit for DLB-MHF-CEVII
For settings and connections on the units mist lubrication, please refer to the assembly instructions of
the device.
