Grease Analysis

Grease Analysis

Grease Analysis

The primary function of grease is to coat the  machine surfaces and to lubricate them without leakage due to centrifugal forces or pressures. Also, Grease must be able to flow throughout all components it is intended to.

A huge fraction of component bearings is being lubricated with grease. Routine grease testing is an important part of predictive and preventive maintenance programs.

 

TUV India’s Routine testing and analysis helps to determine :

  • Grease Condition – normal, contamination present, oxidized, remaining useful life
  • Bearing Condition – the level of tear
  • Frequency of re-greasing – application intervals
  • Condition of the System 
  • Contamination Scrutiny

TUV India provides range of condition monitoring services that consist of elemental examination,  Particle Quantifier (PQ) and wear debris study for Grease applications.

Recommended tests for grease are :
