malossi SKF 6303 ETN9 C3 crankshaft bearing


SKF optimized these new types of bearings, with the collaboration of Malossi's Engineering R&D department, for two stroke scooters and motorcycles competing in the Malossi Trophy series.

crankshaft ball bearings with oversized spherical rollers designed for operating speeds of up to 18,000 RPM and 30 Kw of power.

Another technological step forward that guarantees greater reliability and performance, qualities gladly accept by the technicians in the field.

We'll see if this + loctite 609 solves the derbi clutch bearing failure problems.
