Stihl OEM Needle Bearing (12x15x15) for Piston Pins
QS 9512 003 3061
OEM needle cage bearing from Stihl. This bearing is used between the crankshaft rod and the piston pin. Like all bearings, they tend to wear over time, so if you are replacing the piston or cylinder on an older unit, we recommend putting a new bearing in also.
