SFK "HighQuality" Bearings, incl. HighQuality Seals, Derbi Senda, Teflon cage (SKF 6204/TN9-C4)

In prepared engines it is not recommended to save on the quality of the crankshaft bearing.

In this kit you will find the bearing set with the SFK plastic/Teflon (Polymer) cage from C4 and the seals from the manufacturer ARTEIN. The manufacturer SFK guarantees 25.000 RPM for both models. The version with plastic cage has a higher elasticity than the one with metal cage. These bearings are often used in racing engines. This kit consists of two bearings and two seals of a very high quality.

wARNING: For a good preservation it is important to grease the C4 bearings
