The tapered roller bearing shear test (KRL test) is a specialized method designed to assess the mechanical stability of lubricants under high shear conditions. Conducted according to the DIN 51821 standard, this test evaluates a lubricant’s ability to maintain its consistency (shear stability) over extended periods of use. It is especially suited for lubricants that must endure extreme mechanical shear and high temperatures.
