Axial seals RE

Description

The RE axial seal is an axial shaft seal consisting of a metal case and a moulded elastomer sealing element. It is designed to protect bearings and radial shaft seals against dust, dirt, splash water and other external contaminants, and can operate in both static and dynamic applications.

Assembly

Install the seal carefully to avoid any damage to the sealing lip. It is recommended to chamfer and deburr all lead-in surfaces, lightly lubricate the elastomer sealing element before installation, and avoid hammering the seal into place to ensure proper sealing performance and maximum service life.

Advantages

Excellent protection against dust, dirt and water splashes.
Good dynamic sealing performance.
Low sensitivity to shaft eccentricity, misalignment and runout.
Easy installation without the need for additional axial retaining devices.
Excellent companion seal for radial shaft seals and bearing housings.
The metal insert protects the elastomer sealing element against mechanical damage.
Robust and reliable design for general industrial applications.

Materials

Available in NBR and FKM compounds with hardnesses ranging from 70 to 80 Shore A, incorporating a coated carbon steel metal case; alternatively, it can be supplied with metallic components manufactured from AISI 304 or AISI 316 stainless steel. Hardness values depend on the selected elastomer compound and the specific application requirements. Additional elastomers such as EPDM, VMQ (silicone) and other materials can also be manufactured upon request.

Technical drawing and installation parameters of the RE axial seals

This technical drawing defines the dimensions and geometric variables essential for the correct selection and installation of the RE axial seal, a two-piece axial shaft seal consisting of a metal case and a moulded elastomer sealing element. It shows the critical dimensions linked to the specification tables, such as the inside diameter (Ød), which determines the fit on the shaft, the outside diameter of the metal case (ØD) and the overall height of the seal (H), which sets the axial space required in the housing. Observing these dimensions ensures a firm seat on the shaft, installation without deformation of the metal case and effective protection against dust, dirt and water splashes, in both dynamic and static applications.

Three-dimensional view and components of the RE axial seals

This 3D illustration shows you the basic structure of the RE axial seal. You can clearly identify its elements, the metal case, which forms the seat of the seal, and the elastomer body moulded onto it, from which the sealing lip arises to bear against the counterface. The metal case gives the assembly its rigidity, protects the elastomer element against mechanical damage and allows simple installation without the need for additional axial retaining components, while the lip maintains sealing performance against dust, dirt, splash water and other external contaminants, with low sensitivity to shaft eccentricity and runout.
