Quad and UTV crankshaft bearings - the foundation of a reliable engine

Crankshaft bearings for ATV / UTV are elements that transfer loads between the shaft and the engine crankcase. They are responsible for smooth operation, reduction of resistance and stability of the crankshaft at high revolutions. At Bajamoto you will findquad and UTV crankshaft bearings fromHot Rods, All Balls, ProX, Athena, Wossner andVertex - sets tailored to specific 2T and 4T engine models.

Why are shaft bearings so important?

Crankshaft bearings in ATV engines operate in extreme conditions - at high speeds and variable temperatures. Their wear may cause noise, vibration, loss of power, and in extreme cases - shaft seizure or crankcase cracking. Therefore, during each engine renovation, it is worth replacing the shaft bearings together with the connecting rod and crankshaft.
