Timken Tapered Roller Bearing Cone HM535349 6.75 inch Bore HM 535349 Cone Only

Description

HM535349 Timken Tapered Roller Bearing Cone 6.7500 inch Bore HM 535349 Cone Only This 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.
