Full description: why this specificity TN / 63?

In a competitive engine, each bearing has a precise mission. The 6302 Tn / 63 is selected for:

1. Polyamide cage (TN): Lighter than a steel cage, it reduces inertia and internal friction. It also offers better safety: in case of breakage (very rare), plastic debris are less devastating for gables than pieces of metal.

2. Thermal stability (63): This suffix indicates a tolerance and an internal game adapted to the specific constraints of the block Rotax, allowing the bearing to keep its fluidity even when the motor is at its optimum operating temperature.

3. Reduction of vibrations: The balancing shaft aims to cancel the vibrations of the motor. This bearing ensures that this tree rotates with absolute precision, thus avoiding the touches in the steering wheel and the chassis.

4. Quality of origin: This is the reference recommended by the plant to maintain the technical compliance of your engine in competition.

💡 Michel's trick

"Never neglect this little bend of tree! We tend to monitor the crankshaft, but if the 6302 starts to tire, it's all your engine balancing that takes a shot. My advice: Each full revision of the low engine, check if there is no '' Game 'or if the tree does not scratch itself by turning. If you hear an abnormal whistle sprinkler, it is often him the culprit. For the assembly, as usual: we heats the crankcase gently, we present the bearing straight, and it must go back without forcing!"

🎓 TUTO: Mounting and maintenance

1. Housing cleaning: Before inserting the new bearing, carefully clean the bottom of the crankcase. No impurity should slip under the outer ring.

2. Meaning of installation: Marking (reference) must be facing outwards to remain legible during future inspections.

3. Lubrication: Drop a drop of box oil XPS On the beads before closing the training crankcase.

4. Frequency: We recommend that it replace it preventively during each large low engine revision (about every 50 hours) to ensure total reliability.
