BEARING - TAPER CUP (JLG JL440030-TIM)

A damaged bearing cup can cause uneven rotation and premature wear in rotating assemblies. This aftermarket replacement part references JLG catalog number JL440030-TIM. The taper cup is a type of bearing component that supports radial and axial loads through its tapered raceway. A worn cup may lead to increased vibration and eventual seizure of the rotating element. During routine disassembly, a taper cup often shows spalling or brinelling on the race surface. Keeping the cup in sound condition helps maintain consistent shaft alignment and load distribution.
