Premium Sine Seal oil seal

Oil seals have been around for a long time. They seal a rotating shaft against two environments. Oil seals are standardised in accordance with DIN 3760 and are state-of-the-art. So why have we designed a new oil seal with the Premium Sine Seal and what is different about it compared to other oil seals?

A shaft that seals

Drives in industrial applications are increasingly being operated around the clock with high dynamics in alternating directions of rotation, often up to 8000 operating hours per year. Under these loads, the oil seal (RWDR) is often the limiting link in a gearmotor in terms of service life. Together with Freudenberg Sealing Technologies GmbH & Co KG, SEW-EURODRIVE GmbH & Co KG has developed the Premium Sine Seal, which optimises lubrication in the sealing gap, reduces friction and wear and increases sealing reliability.
