Product Details

Lubricants are often subjected to mechanical shearing, for example in automotive engines. This shearing causes lubricants to lose their viscosity. When subjected to sufficiently large number of cycles of shear, viscosity may drop below acceptable levels and may call of replacement failing which surfaces may become prone to higher wear. Even lubricants that have consistent viscosity through a wide temperature range (high viscosity index) may still be susceptible to loss of viscosity when subjected the mechanical shearing.

Shear Stability Tester is an instrument used to determine an oils ability to retain its viscosity over a number of cycles of shear. The test oil is first measured for its initial viscosity after which it is subjected to shearing in intervals of 30 cycles. Viscosity is measured and compared to the oils initial viscosity following 30, 90 and 120 cycles. Oils that show a lower drop in viscosity over the duration of test are said to have better shear stability than oils that exhibit a relatively higher drop in viscosity.

Company Details

Founded in 1978, Ducom Instruments has led the way in designing and manufacturing advanced materials testing instruments with a specialization in tribology. Applying cutting-edge technology and strong design principles to its products, Ducom focusses on providing customers with an excellent ownership experience starting with ease of use and maintenance.
Our locations in the United States, The Netherlands and in India each have an in-house Research & Development initiative coupled with development partnerships with world renowned institutions. As a result, Ducom holds several proprietary technologies, copyrights and patents with additional filings every year. Many of these technologies are applied to our instruments, and work in the background so users can enjoy better results and user experiences.
Our instruments use components that are manufactured in an AS9100:2009 certified “aerospace grade” manufacturing facility for excellent quality.
We also designed and put into place an active and distributed customer support architecture, which allows our support team to address support requests in multiple modes which including remote support via video conferencing for quick and low cost support to personal visits by our engineers for full on-site support.
Our instruments are operational all over the world. Research labs working on cutting edge technology development which requires advanced and highly configurable test systems to standardized quality control requirements which rely on highly repeatable systems to accurately monitor product quality test instruments by Ducom.
