ERIKS type R (type A according to the DIN standard) is identical in shape to type M, but has a rubber outer case with metal reinforcement on the inside. The rubber creates a good seal in the housing, even if the housing has suffered minor damage or is not in its best condition for other reasons. The RST version has a dust lip. These types are often chosen to replace a type with a metal outer case because they are easier to install and can cope with minor damage to the groove, such as scratches.
Heat resistance
The care taken during the installation process will pay off by allowing the seal to work quietly and operate efficiently behind the scenes of your application.






Amongst the several applications of oil seals, these are the most common three applications – o-rings, spring seals, and lip seals.
Variety of Oil Seals
Other important factors are ensuring the hardness and roughness of the shaft are correct. A shaft hardness of HRC 45 is recommended for a rubber sealing lip, with a roughness of Ra 0.4-0.8. A higher shaft hardness of HRC 60 and shaft roughness of Ra 0.1-0.4 is recommended for a PTFE lip.

The maximum allowable shaft speed is a function of the shaft finish, runout, housing bore and shaft concentricity, type of fluid being sealed and the type of oil seal material.

Power steering oil seals are integral to the functionality of the vehicle's power steering system. These seals are responsible for containing the hydraulic fluid within the power steering mechanism, preventing leaks and maintaining the smooth operation of the steering components. Power steering oil seals contribute to the proper functioning and longevity of the steering system, ensuring precise and responsive vehicle control.


Longer seal life can be expected with shafts having a Rockwell (RC) hardness of 30 or more. When exposed to abrasive contamination, the hardness should be increased to RC 60.
