WearCheck

Our story began about 40 years ago, when founding directors Lesley and Wally Crawford, and Gary Brown set up oil analysis operations in 1976 in a home laboratory. Their initial test portfolio comprised six elements - viscosity, water, fuel, sludge and debris analysis, with no automation. The company employed 10 people and processed less than 500 samples per month.

 

From those humble beginnings, the company has flourished and grown, and today WearCheck is one of the leading condition monitoring specialists on the African continent, processing in excess of 600 000 samples per annum. We have evolved into a one-stop-shop for a vast range of reliability solutions services across many industries, and we are proud to be a member of the prestigious International WearCheck Group (IWG).

 

The IWG is an association of independent laboratories around the globe, dedicated to oil and wear particle analysis. WearCheck’s relationship with the IWG allows for the ongoing exchange of advanced technical information, and the ability to offer a worldwide service.
