A set of FKM double-lip shaft seals from Schmitt with directional oil feed swirl sealing lips and matching ball bearing set with crankshaft bearing (metal cage) in SKF C3 quality.
The oil seals marked RD, LD or WD are installed according to their direction of rotation. They offer maximum sealing and at the same time speed resistance and top durability. The integrated "twist" ensures a permanent, targeted return of lubricants to the bearing or shaft.
Due to their design, Schmitt oil seals with recirculation swirl achieve the best sealing performance even when the shaft is stationary. The FKM material selected here is characterized by excellent resistance to fuels and lubricants.
This set of shaft seals is suitable for Simson moped / mokick S51, S53, S70, S83, SR50, SR80, KR51/2 with M500 or M700 engine housing.

Difference between FPM, FKM, Viton®:
The abbreviations and names mentioned stand for the same basic material, namely fluororubber. FKM is the abbreviation for fluoroelastomers according to the American standard ASTM. Viton®, on the other hand, is a trademark of the company DuPont Performance Elastomers.
In our range, all fluororubber products are designated with the abbreviation FKM.
