Key Features

• Exact OEM Dimensional Spec: — Precision-ground to 1.000" diameter and 10.563" length, ensuring correct bearing seat engagement and eliminating play in the drive shaft bore.
• Direct-Fit Installation: — Engineered as a drop-in replacement for the drive assembly on JTNS20 and JTNSW20 series trowels, matching original mounting points and bearing interfaces.
• Confirmed Fitment: — Compatible with JTNS20, JTNSW20, JTNSW20HTCSL, and JTNSW24HTCSL international ride-on power trowel models.
• Drive System Integrity: — A correctly dimensioned drive bearing shaft keeps rotor blade rotation smooth and consistent; a worn or undersized shaft causes vibration, bearing wear, and loss of blade pitch control.
• Genuine Multiquip OEM Part: — Sourced directly through the Multiquip OEM supply chain, not a third-party substitute, so the metallurgy and surface finish meet the original design standard for this shaft application.

The drive bearing shaft transmits rotational force from the trowel's drive system through to the blade rotor assembly, with the bearing seats on the shaft providing the critical interface that keeps the rotor spinning true. The specified diameter and length are not interchangeable — even minor deviations in shaft diameter can cause premature bearing failure or excessive play that disrupts blade pitch control. When this shaft wears, operators typically notice increased vibration, uneven blade contact with the concrete surface, and accelerated bearing wear in the surrounding drive components.
