Not only do manufacturers like Trelleborg continue to innovate sealing design but they also invest in production technology to meet growing demand and lower total cost of ownership. For example, Trelleborg offers a proprietary HighSpin PDR rotary seal which has a mechanically retained PTFE sealing element and a precision manufactured metal body. Its low friction and power consumption contribute to energy savings in demanding environments like electric vehicle applications and industrial automation.

To achieve performance requirements, an expert sealing partner will not only offer high-performance rotary seals for industrial motor applications but also the technical services to back them up. This may include having multiple manufacturing facilities globally where experts perform rotary testing and use Finite Element Analysis software to specify the best seal for an application.

Today’s focus on reducing global warming and increasing energy saving drives industrial motor OEMs to switch from hydraulic to electric motors. These motors have specific sealing requirements that can only be met with high-speed rotary seals that protect the motor by keeping oil and grease on the rotating shaft while offering low friction characteristics. An expert sealing partner like Trelleborg can help OEMs by determining the optimal rotary seal for the demands of a given application and providing the capacity to deliver the required project volumes.
