The rollset bearings are prelubricated with grease, but must be
periodically relubricated. The manufacturer’s recommendation
is based on environmental conditions. The bearing operational
temperature is from -20°F to +275°F. SuperFlow has observed
normal operating temperatures of 130°F. The required
relubrication cycle is dependent upon the operating condi-
tions, speed, temperature, dust, moisture, and other environ-
mental conditions. The following lubrication guide must be
followed to prevent catastrophic bearing failures:
Conditions Minimum Relubrication Interval
Normal Every 100 hours of operation or 3 months, whichever
occurs first
Dusty Environment Every 50 hours of operation or 1 ½ months, whichever
occurs first
High Moisture Every 50 hours of operation or 1 ½ months, whichever
Environment occurs first
Grease should be added slowly while the shaft is rotated, until a
slight bead of grease forms at the seals. In harsh environments,
relubrication should be as often as necessary to maintain a
slight grease leakage at the seals. Use a lithium base grease, or a
grease recommended by a reputable grease manufacturer as
being suitable for ball bearings and compatible with lithium
base grease.
20.3. Calibration instructions
The sensors used on the AutoDyn should be periodically
calibrated for highest measurement accuracy.
*
NOTE Technical specifications of all sensors can be found in the datasheets included
in the “Accessories and options” section of this manual.
*
NOTE To avoid accidental miscalibration, a safeguard has been built into the
calibration editor. Calibration entries which /- 10% change from the
original calibration value will be rejected. If, for any reason, the real error
exceeds this 10% and the calibration must be adjusted by a greater value, you
will have to modify the configuration file first, using the DEF Configuration Editor.
Final calibration can then be performed following the methods described below.
Of course, apparent calibration drifts of more than 10% should be investigated
as they may point to a defective sensor or a problem with the electronics.
