Benchtop Four Ball Wear and EP Tester K93170 Koehler

Benchtop Four Ball Wear and EP Tester K93170 Koehler

Koehler K93170 Benchtop Four Ball Wear and EP Tester

Overview

The Koehler K93170 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.
