High Speed Spindl-Gard

®

The High-Speed Spindl-Gard® System is today’s highly efficient,
cost-effective method for lubricating spindle bearings, using air/
oil technology.

DESCRIPTION
The High-Speed Spindl-Gard System applies a constant, every
minute, quantity of oil directly to the rotating bearing elements.
The system is recommended for bearings that operate at speeds
greater than 250,000 DN (Bearing Bore in mm X RPM).
The New High Speed Spindl-Gard System incorporates proven
high-speed air/oil spindle lubrication technology into a complete
package. Components include an electric motor driven pump,
with 3 liter (0.8 gallon) plastic reservoir, air/oil dispensing module,
and an optional programmable timer/controller (AC models only).

Overall package dimensions: 415cm x 394cm x 157cm
(16.2" high x 15.5" wide x 6.2" deep).

The package (figure 1) is designed to lubricate from 1 to 8
bearings. Each bearing point will typically utilize an air/oil-mixing
block. Unit can be expanded up to 8 mixing blocks. Each bearing
point is supplied from a mixing block that includes a piston
distributor, an air/oil-mixing chamber and an independent air flow
adjustment. Three different oil outputs are offered 0.025, 0.049,
or 0.082 cc (0.0015, 0.003, or 0.005 cu. in.) at 2.5 to 20 minute
intervals.

•t Integral monitoring of air pressure, lube pressure and oil level.

The system is designed to deliver from 16L (0.57 SCFM) of air @
2 bar (30 psi) (with a .8mm (0.030 in.) orifice) per point to 104L
(3.67 SCFM) of air @ 4.1 bar (60 psi) (with a 1.5mm (0.060 in.)
orifice) per point.

Air is constantly being applied to the air/oil block(s). After a preset
time, the controller activates the pump, which builds system
pressure and fires the Piston Distributors within the air/oil blocks.
The output from the piston distributor is discharged to the air/oilmixing chamber where the constant flow of air causes a thin film
of oil to flow along the delivery tube ID [.6m (2-ft.) min. length] in
a constant wave like motion. This film is then applied in the form
of a very fine spray from a drilled orifice or an SPG-2 nozzle tube
to the bearing elements on a constant basis.

FEATURES/BENEFITS
•t Advanced air/oil concept provides highly effective lubrication,
reduces oil consumption, lowers operating temperature and
protects spindle bearings from coolant ingress.
•t Thin oil film dramatically reduces viscous shear and
hydrodynamic drag on the bearing, resulting in reduced
friction and lower energy consumption.
•t

Integral package design allows for ease of installation.

•t Airflow adjustment for each bearing point.
•t

Oil output selectable for each bearing point.

•t Air/oil lubrication lowers operating temperature which
minimizes thermal distortion resulting in improved production
accuracy.

OPERATION

The optional Spindl-Gard system controller provides monitoring
for low air pressure, low oil pressure, and low oil level. Should
any of the built in sensors indicate a fault condition, the red LED
on the pump illuminates and the fault relay changes state. The
fault relay can be connected to an external alarm or directly to the
spindle drive control for shutdown as desired by user.
