LM67048/LM67010 Tapered Roller Bearings

LM67048/LM67010  sizes 31,75x59,13x15,88  is the most basic and most widely used type of tapered roller bearing. It consists of two main separable parts: the cone (inner ring) assembly and the cup (outer ring). It is typically mounted in opposing pairs on a shaft.
