The new test bench is a large hydro-static test load unit and will be R&D Test Systems’ largest project for a Chinese customer to date. The test bench will be installed in a new-built bearing test center at Zhejiang Tianma Bearing Group (TMB), who is one of the largest bearing manufacturers in China and a global supplier of bearings to the leading wind turbine OEMs.

“It is a milestone project in China, and the cooperation with TMB has been good and very efficient, enabling us to deliver the test bench with a short delivery time,” explains Kasper Willatzen, Sales Manager at R&D Test Systems.

The purpose of testing the bearings is primarily to validate design and lifetime of the main shaft bearing for both on-shore and off-shore Wind Turbines. This is done by applying both static and dynamic loads to the bearings simulating the realistic conditions which the bearings will experience throughout their lifetime in the wind turbine. This kind of test is also called a HALT test (highly accelerated lifetime test) and is essential to secure the durability of the bearings.

“We are very happy with the support and flexibility from R&D Test Systems on this project. R&D has deep knowledge of testing in the wind industry, and they have done several great projects such as LORC’s 25 MW HALT test bench. We look forward to our continued collaboration with R&D Test Systems to strengthen our competencies in wind main shaft bearing development in TMB,“ says Mr. Marco Lu, Director of TMB Advanced Manufacturing Center.
