The Multiquip 21803 Tapered Roller Bearing Set (SKF#32305 J2) is a genuine OEM component designed for Whiteman and International ride-on power trowel models including STX55J6, HHN34TVD, HHN31V, HHXD5-ES, HHXD5, HHXG5, EHHNK5, HHXDF4-DF5, and HHNG5. This is a direct OEM replacement sourced to the original SKF 32305 J2 specification, ensuring correct load ratings, taper geometry, and dimensional accuracy for the application. Ordering by part number 21803 confirms you are receiving the exact bearing set Multiquip specifies for these machines. DHS Equipment supplies this part as an authorized Multiquip OEM replacement.
Key Features
- OEM-Specified Taper Geometry — Manufactured to the SKF 32305 J2 specification, delivering the correct contact angle and load capacity required by the trowel's rotating assembly.
- Drop-In Replacement — Matches the original bearing seat dimensions exactly, allowing installation without machining or shimming adjustments.
- Broad Ride-On Trowel Coverage — Confirmed fitment across STX55J6, HHN34TVD, HHN31V, HHXD5, HHXD5-ES, HHXG5, EHHNK5, HHXDF4-DF5, and HHNG5 models.
- Sustained Radial and Axial Load Handling — Tapered roller design manages the combined radial and thrust loads generated by the trowel's drive system, helping maintain smooth blade rotation under working conditions.
- Genuine OEM Quality — Supplied as a genuine Multiquip part, so tolerancing, surface finish, and material grade meet the original design intent for the bearing position in these machines.
A tapered roller bearing set carries both radial loads and axial (thrust) loads simultaneously, making it the correct choice for rotating shafts that experience force in more than one direction — a common condition in the drive and rotor assemblies of ride-on power trowels. The tapered profile of the rollers and raceways allows the bearing to handle this combined loading efficiently while maintaining precise shaft alignment. When a tapered roller bearing wears or loses preload, operators typically notice increased vibration, elevated heat at the bearing location, or irregular blade behavior — all of which point to the need for prompt replacement to keep the trowel performing correctly.
