A new age in tandem bearing applications

Stanyl® is a versatile polyamide 46 with a unique set of properties - including high mechanical property retention and excellent resistance to wear and friction. Which is why Schaeffler Group - a leading manufacturer of rolling bearings - chose Stanyl for its next generation of tandem bearing applications.

Traditonally, the tapered roller bearing has always been the main bearing option for axle and differential applications. The only problem is that this has sometimes come at the expense of much higher sliding friction – hardly ideal in today’s automotive environment where maximizing fuel economy and driving down CO2 emissions is essential both environmentally and commercially.

Stanyl is now enabling a new generation of high efficiency tandem bearings by achieving all these goals and more through a unique set of thermal, mechanical and wear resistant properties: Reducing drag torque and increasing fuel economy by 1.5% - which in turn reduces CO2 emissions.

Meanwhile the Coefficient of Friction is much lower compared to traditional tapered roller bearings, extending overall service life thanks to bearings generating less heat and thus keeping the axle oil cooler. 

Schaeffler chooses Stanyl

Schaeffler Group - a leading manufacturer of rolling bearings - chose Stanyl® polyamide 46 for its next generation of tandem bearing applications. The reasons are many – not least because Stanyl has delivered a 50% reduction in drag torque.

Says Michael Claassen, Director of Engineering for Schaeffler Automotive Chassis Systems Group: “The tandem is a good example of Schaeffler’s path forward for high efficiency bearings. The Tandem delivers a significant improvement in overall efficiency when compared to traditional tapered roller bearings.

In fact based on its previous performance Schaeffler also chose Stanyl for the construction of the bearing cages, thanks to the material’s heat resistance, dimensional stabilty, and balance between stiffness and flexibliity.
