Paper Thermometer Can Reveal Temperature Spikes
In time-critical situations where real-time infrared thermography is impractical and thermocouple/recording
equipment cannot be installed, consider temperature-sensitive tapes. These tapes are manufactured in a variety
of sensing ranges and will clearly record the peak temperature that a machine area reached since the tape was
first applied. A quick visual check is all it takes to read the "paper thermometer."
Quit Replacing Oil Seals
If you are constantly changing gearbox oil seals,
check the gearbox breather for plugging. When breathers
become clogged, internal gearbox pressure can build
and find its way out through oil seals, creating a false
impression that the seal has failed. This can become more
problematic during summer months.

Try Oil Mist for Better
Contamination Control
In bearing applications where high contamination
levels are a concern, consider converting grease
lubrication systems to oil mist lubrication. Oil mist
systems are slightly pressurized, helping to exclude
contaminants. Use a pure mist system for rolling-
element bearings and purge mist for gearboxes and
journal bearings.
Why Dispersancy Is Crucial for Engine Oils
Coolant contamination, overextended oil drains, water contamination, high
blow-by, long idling, high elevation and exhaust gas recirculation can all result in
the loss of dispersancy in motor oils. This loss can cause engine deposits, sludge,
impaired lubrication and oil flow. ML
