The Multiquip 22577 Thrust Bearing Spacer Eaton is a genuine OEM component designed for STX55J6 and STX55Y6 hydrostatic ride-on power trowels. This factory-sourced spacer maintains the correct axial positioning within the Eaton hydraulic drive system, ensuring the thrust bearing operates within its designed tolerance range. Sourced directly from Multiquip, part 22577 is the exact specification replacement for these STX55 series machines.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Multiquip's original specifications for the Eaton hydraulic system, ensuring correct axial load distribution across the thrust bearing assembly.
- Direct Drop-In Replacement — Engineered to seat precisely within the Eaton drive assembly on STX55 series trowels, slotting into position without rework or shimming.
- STX55 Series Compatibility — Confirmed fitment for STX55J6 and STX55Y6 hydrostatic ride-on power trowels.
- Protects Bearing Longevity — Correct spacer thickness prevents thrust bearing misalignment; a worn or missing spacer accelerates bearing wear and can lead to hydraulic drive instability.
- Hydraulic System Integrity — Maintaining proper spacing within the Eaton drive unit is critical to consistent hydraulic pressure and smooth blade-pitch control during finishing operations.
A thrust bearing spacer controls the axial clearance between rotating and stationary components in a hydraulic drive assembly. In the Eaton system used on STX55 ride-on trowels, this spacer keeps the thrust bearing correctly positioned so axial forces are evenly absorbed during operation. When the spacer is worn, undersized, or missing, the thrust bearing loses its proper seating, which can cause premature bearing failure, increased heat, and loss of smooth hydraulic drive response — directly affecting trowel blade control and surface finishing quality.
