Products and services

Mechanical face seals from Federal-Mogul Powertrain’s GOETZE® brand are found wherever the going gets really tough: in heavy technical equipment such as construction machinery, conveyors, mining machinery, concrete and cement mixers, tunnel boring and agricultural equipment. Our face seals ensure lubricant retention within wheel hubs and axles, track rollers, transmissions and many more components.

We are present all over the world to support our customers, whatever harsh conditions they face. Our portfolio of designs and advanced materials covers applications including some of the biggest equipment around: we manufacture face seals with a diameter of up to 1,425 mm – in fact the world’s largest cast
iron face seals. Within the last 60 years, Federal-Mogul has built a strong position in the global face seals market. We have a reputation for solving even the hardest sealing tasks.
Mechanical Face Seal

Mechanical Face Seal

The cast iron seal rings are preloaded by the elastomer parts.
As a result, the axial load closes the gap between the seal faces, which leads to the sealing function. The relative movement in circumferential direction is only taken place between the seal faces.
The resilience of the O-rings acts in a number of ways:
• exertion of axial load on the metallic sealing faces
• transmission of the friction torque to the housing components
• static sealing between each seal ring and its housing bore

O-Ring Type

O-Ring Type

The most common mechanical face seals design is the o-ring, with two symmetrically tapered seal rings and two o-rings. O-ring designs have two versions - the 76.90H with a ground profile; and the 76.97H with an as-cast profile. In general, both versions are completely interchangeable.

Assembly service

Assembly service

We offer assembly tools to optimize the assembly process and to ensure a proper function of the seals. Together with understanding the varying needs for series production, and maintenance tasks, we are able to offer customer specific assembly tools for special requirements. This customization extends to sealing solutions using new materials, designs, and applications.
