Rotary shaft seals from ElringKlinger Engineered Plastics – Resistance with every rotation
As a solutions developer and, among other things, a manufacturer of rotary shaft seals, ElringKlinger Engineered Plastics produces high-quality rotary shaft seals for numerous demanding applications. ElroSeal™ rotary shaft seals reliably seal off rotating shafts—even in the presence of aggressive media, elevated temperatures and challenging lubrication conditions. Manufactured from high-performance plastics such as PolytetraflonTM-PTFE,MoldflonTM fluorothermoplastics, and Elringplast PFAS-free materials, they are characterized by outstanding thermal and mechanical properties, minimal friction and the anti-adhesive behavior of the sealing lip. For electric motors, we also offer the ElroSeal™ G grounding ring, which effectively dissipates bearing currents and protects engine components from damage.
Rotary sealing system
Reliable seal for rotating shafts through a precisely fitting sealing lip with minimal frictional resistance.
High-performance plastics as the base material
Use of PolytetraflonTM-PTFE and other high-performance materials with excellent sliding properties and chemical resistance.
From standard to custom designs
Comprehensive shaft seal catalog for every application - from highly dynamic electric drives to certified designs for the food and pharmaceutical industries.
When the shaft is running, but the gasket can’t keep up
High speeds, aggressive media and special protection requirements often overwhelm conventional shaft seals.
Wear due to insufficient sliding properties
Conventional materials generate high friction at the sealing lip. This leads to accelerated wear, increased energy consumption and premature failure of the rotary shaft seal.
Failure due to insufficient lubrication and dry operation
If there is insufficient lubricant, unsuitable sealing materials overheat and lose their sealing effectiveness - with serious consequences for the shaft and bearings.
Corrosion caused by aggressive media
Oils, fuels, coolants, or chemicals can attack, swell, or degrade sealing materials, especially in the case of standard materials without sufficient chemical resistance.
High shaft speeds and bearing currents
Highly dynamic applications and electric motors generate special stresses: Bearing currents can cause damage to shaft seals without proper dissipation and lead to system failures.
Limitations with unhardened shafts
Many rotary shaft seals require hardened mating surfaces. If this is not the case, wear increases significantly - or the application fails entirely due to the material combination.
Lack of approvals for regulated industries
In the food and pharmaceutical industries, material approvals, physiological safety and a design without dead space (hygienic design) are absolutely essential. Standard solutions often fail to meet these requirements.

Integrating the rotary shaft seal correctly - Why the material determines the field of application
Not every rotating shaft is the same - and not every shaft seal is suitable for every shaft. The decisive factor is the combination of material, geometry and mating component. High-performance plastics offer decisive advantages over elastomers wherever media resistance, dry-running capability, or special purity requirements are needed. This applies to traditional industrial and mechanical engineering applications as well as highly dynamic electric drives or regulated sectors such as food and pharmaceuticals. ElroSeal™ rotary shaft seals are manufactured from various high-performance plastics and precisely tailored to the specific requirements - including speed, media, temperature and surface quality of the mating surface. The result is not a compromise product, but a sealing solution that functions reliably over the long term for exactly this shaft, in this application and with expert oil seal assembly.
