Taiwan Gun provides a brief look at the variety of bearings available for airsoft gearboxes. The presentation highlights various diameters and styles, emphasizing that not all small metal circles are created equal when it comes to internal upgrades. It’s a bit like a jewelry showcase, but with more grease and fewer diamonds.

The disassembly process involves opening the gearbox by removing its housing screws with a power drill or screwdriver. Once the internals are exposed, the gears and cylinder assembly are set aside to reach the bearings. Removing them requires a steady hand and a specialized tool to punch them out of the shell without turning the whole setup into a pile of expensive scrap metal.

Reassembly focuses on the precision required to seat new bearings correctly. The guide demonstrates how to select the proper size for a flush fit, warning that forcing the wrong part is a recipe for a bad day at the range. Once the bearings are secured, the gearbox is buttoned back up, leaving the viewer ready to get back into the game with a smoother cycle.
