Heavy Duty 12mm Wrist Pin Bearing for 50cc 2-Stroke Scooters and Mopeds
This heavy-duty wrist pin bearing suits 50cc 2-stroke engines, helping keep your scooter or moped running reliably. It keeps the engine steady at high RPM, so it is an important part for performance work or routine upkeep. The bearing has a silver-plated cage that copes with intense heat while cutting down on friction. It is one of the scooter pistons & piston rings parts that can noticeably affect how long your engine lasts and how it performs.
Build and Performance
The bearing uses a heavy-duty silver cage, which conducts heat away better than standard bearings. This helps it last longer and hold up under load. Its precision needle rollers are made of hardened steel, allowing the piston to move smoothly and handle heavy loads. It is well suited to sport and mid-race use, where crankshaft RPM goes beyond factory specifications.
Fitting and Upkeep
The wrist pin bearing should be replaced during a top-end rebuild, since neglecting it can lead to engine failure. Before fitting, coat the bearing well with 2-Stroke Racing Oil so it is lubricated right from the first start. It is also worth checking the tension of the piston circlips during the job for dependable operation.
