Looking to replace metal, consolidate parts, and reduce system costs in their
chain tensioner Schaeffler turned to Stanyl® TW341 from DSM Engineering
Plastics. The chain tensioner is used in high volume engines that are supplied
to Ford Motor Co. Throughout the evolution of the powertrain, Stanyl has been
and remains the best material for tensioners.
Stanyl offers better wear performance than high molecular weight PA66,
provides the highest safety and durability factors, and allows for the
reduction of noise generated by the chain. In addition, it has the best
fatigue and creep resistance at temperatures and better fatigue resistance
than PA66. Stanyl is an extremely high performance material delivering
excellent wear and friction properties, high stiffness at elevated
temperatures, high fatigue resistance, low creep behavior, and retention of
properties after oil aging.
DSM provided structural analysis on the tensioner for Schaeffler as well as
technical and design support to help successfully replace metal and optimize
the design. DSM has the application experience and tools to help optimize
designs for tight spaces. Application and design engineers take the time to
understand the system, know what is important, and how this affects the
loading and performance of the structural parts.
