BEARING - CUP (JLG JL440018)

A worn bearing cup can lead to increased friction and premature failure of the rotating assembly it supports. This aftermarket replacement part cross-references JLG part number JL440018. The bearing cup serves as the outer race for tapered roller bearings, providing a hardened surface for the rollers to travel against. When the cup becomes pitted or spalled, the bearing may seize or generate excessive heat during operation. In a typical application, the cup is pressed into a housing and must be replaced whenever the bearing set is serviced. Verify the serial number or application, then call (562) 693-7748.
