TRANSMISSION SEAL RINGS MELDIN®

Efficient system design 
The seal designs and MELDIN® materials achieve low friction and ultra low leakage levels minimizing system energy losses. With consistent leakage levels over all operating conditions, the oil pump design can be optimized thus eliminating oversizing. With special designs of the cross section, the drag losses are reduced. 

Design expertise 
With Saint-Gobain as partner, you get access to highly experienced engineers. We design a seal ring optimized for temperatures, load conditions, and required leakage levels to fit the surrounding components. The whole design process is led by us.

Reliable and stable function over lifetime
MELDIN® transmission seal rings ensure a consistent and low leakage with no decrease in performance over the lifetime of the vehicle, leading to steady, constant shifting and driving characteristics for an enjoyable driving experience. 

Reduced manufacturing cost
Due to the low wear of certain MELDIN® grades, a rougher surface on the mating component is acceptable without negative impact on the durability, positively impacting the manufacturing costs of the adjacent metal parts.
