Description

Crankshaft Bearings steel cage Stage6 R/T with Oil Seals

Especially in high-performance engines, the quality of crankshaft bearings and oil seals is crucial. Stage6 has upgraded their kits by pairing their already top-tier SKF bearings with bold orange FKM oil seals from the Stage6 R/T line – great look, even better performance.

Fits scooters with Minarelli / Minarelli Replica 2-stroke engine, please check dimensions before ordering.

Crankshaft Bearing Types

The bearings are available in 2 versions

- Polymer cage – designed for racing use. The polymer version offers more flexibility and reduced friction compared to metal cages.
- Metal cage – built for daily street use. More durable than the polymer version, ideal for long-term loads.

Both types are SKF-approved for speeds up to 20,000 RPM. Proper lubrication and correct installation are essential for longevity.

We recommend the metal cage version for everyday use. These bearings handle long-term stress well and are suitable for both tuned and stock engines.

The newly developed orange FKM oil seals are produced using cutting-edge technology. Compared to older models, they offer longer lifespan and reduced friction for better overall engine efficiency.

Bearings and Seals Set:

2x crankshaft bearing SKF 6204-C4 20x47x14mm metal cage
1x oil seal FKM 20x42/43x8mm
1x oil seal FKM 20x30/34x6mm

Notes and Safety

Crankshaft bearings for motorcycle, scooter and moped

Crankshaft bearings ensure the smooth operation of engines, whether on scooters, motorcycles or mopeds. The crankshaft is an integral part of the engine and the associated bearings and seals must be in perfect condition.

A crankshaft bearing set consists of ball bearings and oil seals. They are usually sold as a complete set and must be replaced each time the crankshaft is installed/re-installed.

What are the symptoms of defective crankshaft bearings?

The main symptoms of a defective crankshaft bearing are:

Unusual metallic noises coming from the direction of the crankshaft.
Unusual vibrations of the vehicle.

Defective bearings must be replaced immediately, otherwise there is risk of further damage to the engine. There are many different tools for crankshaft removal or bearing pullers.

You can see how to change crankshaft bearings in our crankshaft disassembly and assembly tutorial.
