A set of high quality Naraku SKF crankshaft bearings incl. premium FKM shaft seals suitable for Peugeot Euro 2 vehicle type with upright engine built from 2004 and up, e.g. as installed in Peugeot Vivacity 50, TKR 50 and Speedfight 50.
The bearing set includes one SKF crankshaft bearing each left and right with C3 and C4 bearing tolerance and two FKM crankshaft sealing rings. The polymer-plastic cage has a higher elasticity and thus reduces inherent friction: the bearings run cooler and lighter. However, such bearings are more sensitive to improperly adjusted engines. The polyamide plastic cage must not be exposed to temperatures above 120°C on a permanent basis. For this reason, the bearings should not be mounted in engines with catalytic converters.
Please note! When changing the crankshaft always use new bearings and oil seals!! Always install the half-open bearing side facing the crankshaft.
FPM, FKM, Viton®:
Behind the abbreviations or names mentioned is the identical basic material - fluororubber. FKM is the abbreviation for fluoroelastomers according to the American ASTM standard. Viton®, on the other hand, is a trademark of the company DuPont Performance Elastomers.
In our range, all fluoro rubber items are designated with the abbreviation FKM.
