LUBMASTER
LUBMASTER combines the industry standard methods for calculating bearing performance with the SPM method
( LR/ HR readings) . It allows the user to compare the theoretical operating condition of a bearing under given operating
parameters with its actual operating condition as reflected by the measured shock values.
LUBMASTER is based on three sources:
1 SPM' s algorithms for bearing condition evaluation, derived from empirical
data obtained during decades of laboratory and field tests.
2 The formulas recommended by ISO 281 for rating life calculation.
3 The formulas used by major lubricant and bearing manufacturers to calculate
life adjustment factors which quantify the effect of lubricant type, viscosity,
load, and temperature on bearing life.
LUBMASTER works with the CondmasterPro bearing catalogue data ( bearing type, bearing size, and dynamic load
rating) for bearings with standardized dimensions according to ISO 15, ISO 355, and ISO 104.
Specifically, LUBMASTER can be used for:
1 Training - the graphic display of the SPM evaluation graph clearly shows
the relationship of shock values and condition codes.
2 Calibrating SPM measuring points - by comparing calculated LR/ HR values
with the measured results, one can determine a calibration constant
( COMP No.) for each individual bearing application.
3 Assessing alarm limits - the display shows the dynamic range of LR/ HR
readings, LUB and COND numbers.
4 Optimizing lubrication conditions - by changing lubrication data
( e.g. lubricant type, viscosity) , one can simulate the effect
such changes would have on bearing life expectancy.
For this, you have two functions, the evaluation graph and the life time graph ( see) .
