Volvo Car Corporation and Mitec-Jebsen Automotive Systems (Dalian) have agreed a deal to supply the balance shaft for the automaker's new GEA3 engine. Production starts in 2016.

Mitec-Jebsen, a joint venture of Jebsen Automotive Technik (JAT) and MITEC Automotive, will supply 220,000 balancer systems for the GEA3 every year from 2016 to 2022, manufacturing and integrating balancer shafts, oil pump steel gears and crankshaft gears.

The new 1.5 litre, three cylinder engine which Volvo will offer worldwide, is undergoing final development and testing in Sweden and will be manufactured in China for use in several current and new Volvo models and cars produced by Geely, Volvo Car's Chinese owner. 

For this cooperation, Volvo hopes to localise with a balancer supplier in China to help ensure flexible, rapid and cost effective production for the GEA3.

With design expertise and advanced manufacturing technologies and processes, Mitec-Jebsen was the stand-out quality choice for Volvo, the automaker said.

Precision components

Mitec-Jebsen balancer shaft systems are gear actuated, rotating at twice the crankshaft speed to meet the highest precision requirements. They are used by many leading carmakers in China, including Volkswagen and Shanghai General Motors.

The balancer shaft is a necessary part of every three cylinder automotive engine, preventing vibration and noise being transferred to the chassis and thus delivering a smoother ride. A highly complex component, the balancer shaft must be expertly designed and precisely machined to ensure compatibility with the engine system. Furthermore, this precision must be maintained during production to ensure that each balancer shaft set is fit for purpose.

Expert partner

"A key factor for Volvo was that Mitec-Jebsen is not only a total solution provider capable of developing, engineering and manufacturing complex components but also a supplier that can integrate balancer shafts and gears into a complete balancer system,"  said Arnie Jensen, director of JAT.

"Our value lies in our understanding of how to design, develop and deliver the exact solution that the customer needs. In the end, this is just as important as the premium components we produce."

The combination of JAT's management expertise, Mitec-Jebsen's China-specific manufacturing and application experience, and Mitec Europe's technical support was an ideal fit for Volvo, according to the automaker. This is the first time Volvo and Mitec, the world's leading balancer shaft supplier, have worked together.

Following more than a year of collaboration to develop and refine the balancer design for the GEA3, Volvo and Mitec-Jebsen remain in close contact as the arduous testing and certification process continues. Mitec-Jebsen is also preparing to expand its manufacturing facilities in Dalian to ready itself to begin mass production of components for the new engine.


Mitec-Jebsen Automotive Systems (Dalian) was established in 2007 as the first foreign-owned company in China to produce balancer shafts for the premium automotive market. The auto parts industry leader is now expanding its portfolio with the production of high-precision gears.
