Description
20x52x12mm Crankshaft Bearing for Genuine Scooters
This is an authentic OEM crankshaft bearing made for the Genuine Black Cat 50, Buddy 50, Rattler 50, and RoughHouse 50 scooters. Its job is to hold the crankshaft in place, keeping it turning smoothly and properly aligned. Similar to other Genuine Buddy scooter components, it sits in the same spot as the bearing it replaces, so owners can carry out upkeep without much hassle.
Construction and Design
The bearing is an open, single-row deep-groove type with no seals. Steel balls held in a cage handle both radial loads and light axial loads. Because it is open, the two-stroke oil mixed into the scooter's fuel can reach it and lubricate it during running. Built this way, it is meant to hold up to regular riding while keeping the crankshaft well supported.
When to Replace
If the crankshaft feels loose or you hear unfamiliar noises while the scooter runs, it may be time to swap this bearing out. A worn or damaged unit can cause weak performance and, in serious cases, engine failure. Replacing it during an engine rebuild is a routine step that helps bring the scooter back to its original running condition. Checking the bearing on a regular basis can help you catch problems early.
