MU 200178370

Frequently Asked Questions

Q: What is the purpose of the MU 200178370 thrust bearing?
A: The MU 200178370 is an OEM thrust bearing designed for Multiton TM 55 series manual pallet jacks. Thrust bearings support axial (vertical) loads in the hydraulic unit assembly and allow smooth rotation of the pump shaft or handle pivot under load. This bearing separates and supports the surfaces that slide under pressure.

Q: Which components does this bearing support in TM 55 jacks?
A: The MU 200178370 is used in the hydraulic pump assembly to support the pump shaft under vertical load from the lift mechanism. It may also be used in the handle pivot assembly to reduce friction during handle operation. Verify the exact location in your hydraulic unit before ordering to ensure compatibility with your assembly configuration.

Q: What material and design does this bearing have?
A: The MU 200178370 is a precision-manufactured thrust bearing with hardened steel races and rolling elements. The bearing is designed to support vertical loads while maintaining low rotational friction. It may include a seal ring to keep hydraulic fluid in and contaminants out of the bearing cavity.

Q: How long does this bearing last in normal operation?
A: With proper hydraulic fluid maintenance and regular lubrication, the MU 200178370 typically provides several years of service in normal warehouse use. Bearing life depends on load intensity and maintenance frequency. Replace the bearing if you notice grinding noise, increased resistance during operation, or if the pump shaft shows vertical play or wobbling.

Q: Is this an exact OEM replacement bearing for TM 55?
A: Yes, the MU 200178370 is the genuine Multiton OEM part for TM 55 hydraulic assemblies. It is manufactured to original specifications including bore diameter, outside diameter, width, and load rating. Aftermarket bearings may have different tolerances or material grades that could affect pump performance or bearing life.
