The bearing 6202 TN9 C4 (15×35×11) is a Balancing Shaft Bearing used on engines IAME X30, KZ and Reedster. It is identified under the room n°121 on the technical view IAME. This bearing is located at the end of the balancing shaft, on the crankcase side, and allows this shaft to rotate freely, at very high speed, maintaining a perfect alignment.

Role of rotation

This bearing supports one of the support points of theBalancing shaft, an element used for reduce vibrations generated by the crankshaft. By turning in the opposite direction to the crankshaft, the balancing shaft compensates the moving masses and balances the engine.

The bearing 6202 TN9 C4 allows this fluid and stable rotation, while absorbing radial loads and limiting friction between metal surfaces. It participates directly in the engine stability and Low-engine longevity.

Technical specifications

• Full reference: 6202 TN9 C4
• Dimensions15 mm (inside) × 35 mm (outside) × 11 mm (thickness)
• Type: one row ball bearing
• Cage: TN9 reinforced polyamide), lighter and quieter than metal cages
• Internal Game: C4, i.e. an increased game to compensate for thermal expansion at high speed and avoid any tightening

Benefits of bearing 6202 TN9 C4

• Excellent holding at the high rotation speed Balancing tree
• Reduction of mechanical noise and internal friction
• Better temperature resistance high and with variations in load
• Enhanced durability thanks to polyamide cage and SKF quality
• Optimal maintenance internal engine geometry, ensuring precise balancing

The bearing 6202 TN9 C4, coin No121 on the technical view IAME, is therefore an essential component for the fluidity, reliability and stability X30, KZ and Reedster engines. Its precision and design adapted to thermal stresses ensure a perfectly balanced rotation of the engine in all conditions.
