8mm stainless steel bushings
Stainless steel sliding bearings for gearbox with 8mm holes.
The torque is transferred from the gears to their bearings. In some firearms, the bearings are made of nylon and cannot withstand heavier loads caused, for example, by a stronger spring. If the bearing breaks during firing, the wheel will be misaligned from its intended position and the gear teeth will be broken in a matter of moments. Replacing the bearings is the first step in any upgrade to your firearm's performance.
