SKF 6302 TN9 / C3 Bearing

🏎️ Full description: the SKF technological advantage

Why is this bearing so popular for low engine Rotax ?

1. Cage TN9 (polyamide 66): Unlike metal cages, the TN9 cage is lighter and offers a better coefficient of friction. It is also more resistant to brutal acceleration and deceleration (very common in karting).

2. Game C3 (high speed): This additional internal game is essential to compensate for the thermal dilatation of the tree and the crankcase. Without this game C3, the bearing may bride hot, causing a mechanical case.

3. Quality SKF Explorer: This range represents the top of global accuracy. It guarantees silent operation, a reduction in vibrations and extended life, even under intense charges.

4. Mechanical fluidity: By releasing the constraints on the balancing or transmission shaft, you make it easy to take the turn of your engine.

💡 Michel's trick

"The SKF in TN9 / C3, it's a bit the 'roll' of the box bearing! CAUTION However: the polymer cage (plastic) does not like the ultra-aggressive solvents or the heating on the flusher. My advice: for the mount like a pro, put the bearing in the freezer and heat the housing cleanly 80 ° C.. The bearing must be installed without any force. And if you see that the plastic cage starts to yellow or become brittle on an old bearing, do not look, change it to the direct before it explodes in the gables! "

🎓 Tuto: installation and maintenance

1. Preparation: Clean the housing housing. Check that the range of the shaft (15mm) is not marked or worn.

2. Insertion: Use a socket that supports exclusively On the outer roller ring to insert it into the crankcase. Never tap on the inner ring!

3. Lubrication: Once in place, soak it with box oil XPS (red oil Rotax). The TN9 cage must always be lubricated to maintain its flexibility.

4. Replacement frequency: Intensive use, a check at each revision of 25 hours is recommended. At the slightest "scrap", the replacement is mandatory.
