Gear Lubricant Testing

Gear lubricant testing is essential to evaluate the critical properties of gear lubricants and their performance. These tests include four-ball wear extreme pressure, pin and vee wear, foam testing, and more. By conducting these tests, engineers are better able to measure the viscosity, shear stability, wear performance and other parameters of gear lubricants. This helps to ensure that gear components continue to operate with minimal wear under varying conditions. It also allows engineers to assess the effectiveness of different gear lubricants in a range of applications. Ultimately, this provides them with data for making informed decisions about which gear lubricants offer the best cost-benefit analysis for their particular needs. With reliable gear lubricant testing results at hand, teams can make sure that gear components are working optimally while avoiding unexpected breakdowns. Recording and tracking gear lubricant testing results over time can give invaluable insight into the long-term performance of gear lubricants and their components.

Savant Labs offer most of the gear lubricant testing required under SAE J2360 specification for Automotive Gear Lubricants for Commercial and Military Use.
