Benchtop Four Ball Wear and EP Tester K93179 Koehler

Benchtop Four Ball Wear and EP Tester K93179 Koehler

Koehler K93179 Benchtop Four Ball Wear and EP Tester

Overview

The Koehler K93179 Benchtop Four Ball Wear and EP Tester is a precision instrument designed to evaluate the wear resistance and extreme pressure (EP) properties of lubricants. It utilizes a four-ball test method, where a rotating steel ball contacts three stationary steel balls immersed in the lubricant under controlled conditions.
