The Multiquip 21802 is a genuine OEM Tapered Roller Bearing Set (SKF30307 J2/Q) designed for HHN and HHX series Whiteman ride-on power trowels. This bearing set delivers the precision load-handling performance these machines demand during continuous finishing operations. Confirmed fitment includes the HHN34TVD, HHN31V, HHXD5-ES, HHXD5, HHXG5, EHHNK5, HHXDF4-DF5, and HHNG5 models. Sourcing a direct OEM replacement like the Multiquip 21802 ensures the bearing seats and preloads exactly as the original specification requires, with no guesswork on dimensional fit.
Key Features
- OEM-Grade Tapered Bearing Tolerancing — Manufactured to the SKF30307 J2/Q specification, this bearing set meets the exact radial and axial load ratings required for ride-on trowel drive applications.
- Drop-In Replacement for HHN and HHX Trowels — Engineered to seat directly into the original bearing housing, preserving correct preload and shaft alignment without additional machining or shimming.
- Broad Fitment Across Whiteman Ride-On Trowel Models — Covers HHN34TVD, HHN31V, HHXD5-ES, HHXD5, HHXG5, EHHNK5, HHXDF4-DF5, and HHNG5 models with a single part number.
- Sustained Blade Rotation Under Load — A correctly seated tapered roller bearing supports smooth, consistent blade rotation across full-width finishing passes; a worn bearing introduces vibration, uneven blade pitch, and premature drivetrain wear.
- Genuine Multiquip OEM Component — Sourced directly from Multiquip, this part carries the same part number used by authorized service centers, ensuring traceability and confidence in every repair.
A tapered roller bearing is designed to handle both radial loads (forces perpendicular to the shaft) and axial thrust loads (forces along the shaft) simultaneously — a combination that is essential in the demanding rotational drivetrain of a ride-on power trowel. In these machines, the bearing supports the rotating blade assembly through hours of high-torque finishing work, keeping the shaft centered and the blades running true. When a tapered roller bearing begins to wear, operators will typically notice increased vibration, inconsistent blade pitch, or unusual noise from the drive assembly — all signs that replacement is overdue.
