KRL
Shear stability tester (KRL) for determining the mechanical shear stability of lubricating oils
The shear stability tester (KRL) is designed to carry out tapered roller bearing shear stability tests on lubricating oils by evaluating the viscosity loss that occurs before and after a shear process. This is especially important for lubricants used in high-load environments, like tapered roller bearings, where maintaining viscosity is critical to ensuring long-term performance.
Standards
CEC L-45-A-99, DIN 51350-6
Applications
Commonly used for testing industrial lubricating oils, greases, and lubricants in tapered roller bearings, this tester helps ensure reliable performance in heavy-duty applications.
