The needle bearing of the connecting rod - piston pin is a component of the crank-piston system of an internal combustion engine, which allows the smooth and trouble-free movement of the piston pin relative to the connecting rod. The bearing consists of an outer ring, an inner ring and needles that are pressed between these two rings. The needles are made of hardened steel and are highly resistant to load.

Needle bearings for scooters, mopeds and motorcycles are available in a variety of sizes and dimensions, so it is important to choose a bearing with the right specifications for your engine. Needle bearings are an important part of the crank-piston system and their proper operation is essential for the proper functioning of the engine.
