A set of high quality Naraku SKF crankshaft bearings incl. premium FKM shaft seals suitable for various scooters with Piaggio 2-stroke engines, air or water cooled.
The bearing set includes one SKF crankshaft bearing each on the left and right side and two FKM sealing rings for the crankshaft. The polymer-plastic cage, whose elasticity is higher, 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.
Explanation of difference between FPM, FKM, FKM®:
Behind the abbreviations or names mentioned is the same basic material, namely fluororubber. FKM is the abbreviation for fluoroelastomers according to the American ASTM standard. FKM®, on the other hand, is a trademark of DuPont Performance Elastomers.

In our product range, all fluororubber articles are designated with the abbreviation FKM.AI-translation
