Radial shaft seals are trailing seals used particularly for sealing oil-lubricated bearings.
These ready-to-use elastomer seals usually have a metal reinforcement or housing
The sealing lip is usually a nitrile rubber and is normally pressed against a contact surface on the shaft by means of a spring
Depending on the seal material and the medium to be kept in or out, radial shaft seals can be used at temperatures between 60 and +190 °C
The contact area between the seal lip and the contact surface is vital for the effectiveness of the seal
The surface hardness of the contact surface should normally be at least 55 HRC, and the depth of hardening should be at least 0.3 mm
Surface roughness according to ISO 4288:1996 should be within the guidelines of Ra = 0.2 to 0.8 mm
In applications with low speeds, good lubrication and minimal contamination, a lower hardness can be used
To prevent pumping of spiral grinding grooves, insert grinding is recommended
If the radial shaft seal is to keep the lubricant inside the bearing housing, the seal should be mounted with the lip inwards
If the main task is to keep out contaminants, the lip should point outwards
