The PCM 121412 E SKF is a sleeve bearing manufactured by SKF. It has an outer diameter of 14mm, an inner diameter of 12mm, and a length of 12mm. It is used for applications that require motions less than 360°, such as automotive applications and electric motors. The bearing is made from a special polyamide, with steel and PTFE to minimize the effect of dirt, dust, water, and other external contaminants on the bearing's performance. It is also oil impregnated, for smooth operation and high fatigue life.
