(75) Rolling of crankshaft 6206 TN9 C4

Bearing of Vilebrequin SKF 6206 TN9 C4 – Origin IAME X30

This high-precision ball bearing is the original part certified by the IAME plant for the low motor of the X30. Made by SKF, the world leader in rolling, this model TN9 C4 is specifically designed to withstand extreme thermal and mechanical stresses of karting competition.

Characteristics Technical:

• Reference Origin IAME: Broken view number 75.

• Dimensions: Standard 6206 (Internal diameter 30mm / Exterior 62mm / Width 16mm).

• Cage TN9: Polyamide reinforced glass fibre box. Lighter than a steel cage, it reduces friction and better resists sudden accelerations.

• Game C4: Internal game increased to compensate for thermal expansion of crankshaft and crankcase at high temperature.

• Make: SKF (IAME original quality).

The Magickart Commitment: A crankshaft bearing does not tolerate the approximation. Magickart guarantees SKF certified origin at the lowest price in France and Italy!

The Council of Michel (Magickart): The heart of the low engine

"The 6206 TN9 C4 bearing allows your vilo to spin without blowing at 16,000 laps. My expert advice: Never mount a bearing with a lower set (type C3) on an X30, because once the engine is warm, the bearing would tighten and destroy your crankcases.

Products that go well together:

• Spi joint pouch (R76/R77): If you change the bearings, change the spi joints. A dry or marked spi is an assured air intake.

• Oil Lexoil 996 Evo 2: To lubricate these high precision bearings with the best possible protective film.

• Complete motor seal pouch: To close your casings cleanly after surgery.

A little pro secret: To mount your bearings without typing them like a deaf, heat your crankcases in the heat stripper or in the oven (about 80-100°C). The bearing must fall into its housing almost alone. If you need to type, use a socket that presses the outside cage bearing, never on the inside cage! At Magickart, we don't joke about precision mechanics."

Tuto: When to change your vilo bearings (R75)?

1. The diagnosis: If you feel a radial game (up and down) at the end of the crankshaft or if you hear an abnormal whistle at high speed, your bearings are tired.

2. Frequency: On an X30, it is generally recommended that all bearings be replaced 30-40 hours in use competition to avoid any major damage.

3. Mounting: Make sure the "SKF" marking is visible outwards.

4. Lubrication: Before closing, put a few drops of oil 2 times directly on the balls to ensure lubrication from the first rounds of launcher.
