Trelleborg launches seals designed for next-generation electric cars
Trelleborg Sealing Solutions introduced the HiSpin PDR RT and HiSpin HS40, two seals developed for e-Mobility applications.
HiSpin PDR RT is constructed from two parts: a precision manufactured metal body and a mechanically retained Turcon polytetrafluoroethylene (PTFE) sealing element. It has a custom-designed lip with additional features that improve performance and behavior of lip laydown profile on shaft, crimped into a precision-machined body.
Capable of speeds of 60 m/s and beyond, it has both high- and low-temperature capability. Able to handle pressure, it is universally compatible with chemicals, and its low friction coefficient means it is capable of dry running. Prototypes are offered through a recently launched Rapid Prototype Service introduced to support customers. A conductive PTFE based grade is available.
HiSpin HS40 is of a familiar product type to automotive customers. With a bi-directional hydrodynamic lip feature, it has negligible frictional torque at high speeds. As a result of extensive finite element analysis (FEA) studies, its rubber lip geometry and flexible design give optimum lip contact on the shaft, ensuring optimum static and dynamic sealing performance.
The seal is manufactured using proprietary XLT fluoroelastomer (FKM) compounds to meet higher speeds and a wider operating temperature range. Compatible with synthetic automatic transmission fluids (ATF), it is produced using proven conventional high-volume manufacturing processes. Capable of speeds up to 40 m/s, the HiSpin HS40 has the ability to handle run out and is easy to install.
