- Warranty
- 6 months
A worn bearing cup can cause uneven rotation and premature failure of the supported shaft. The MB1B3978-TIM is an aftermarket replacement part, cross-referenced to the Mitsubishi catalog number. This taper cup is a type of bearing component that provides a hardened raceway for tapered rollers. Its primary mechanical function is to support radial and axial loads while maintaining precise shaft alignment. A common failure consequence is increased friction and heat generation, leading to possible seizure if not addressed. Keeping the taper cup in sound condition helps maintain consistent rotational accuracy. Verify the serial number or application, then call (562) 693-7748.
