Precision gears



PRECISION GEARS MANUFACTURED WITH COLD FORGING

JG Automotive is the commercial office of O-OKA in Spain, world leader in cold forging precision, specialists in the manufacture of gears of high level of design and complexity for the automotive sector.

Innovating in the concept of technology and improving the conventional machining process, we introduce the forging technique and develop a new possibility in gear technology.

INCREÍBLE MEJORA DE LA RESISTENCIA: APLICANDO LA FORJA

The comparative results of the gear resistance made at the University of Aachen, Germany Approx. 50% improvement in fatigue resistance has been confirmed by comparative tests of fatigue Ooka forged gears and conventional machining gears.

Since the flow line is kept (not cut), forging ensures higher strength compared to machining.

Shift feeling is significantly increased

Gears formed by Ooka’s precision forging technology provides a better shift feeling, We have received tremendous favor from our customers.

Compact transmission design

Integrating the clutch gear and the main gear body into one piece, enables a substantial compactness and weight reduction of the transmission. Furthermore, forging of recessed gear design creates the innovative impact.

Cutting-edge quality in production processes

O-oka complies and is certified with TS16949 international Quality Management system in the automotive industry. At the same time O-oka has established quality system that suits any customer requirment in the world. O-oka is not only certified ISO14001/2004 but strives and supports the clean-plant policy of forging industry.
