The Multiquip 11139 Bearing Flange Housing 40M-2 is a genuine OEM component designed for HHN and HTN series ride-on mechanical power trowels, including the HHNG5, HHN34TVD, HHN31V, HTN28K, HTN27K, HTNS5S-2, and EHHNK5 models. As a direct Multiquip OEM part, 11139 is manufactured to the same specification as the original, ensuring a correct fit within the trowel's rotor drive assembly. Confirm your model code against the fitment list above before ordering to ensure compatibility with your specific configuration.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design specification, ensuring the bearing bore tolerances and flange dimensions match the rotor assembly exactly as built.
- Direct-Mount Replacement — Bolts into the existing mounting position on HHN and HTN series trowel rotor assemblies, using the original hardware and alignment points.
- Broad HHN and HTN Series Coverage — Compatible with HHNG5, HHN34TVD, HHN31V, HTN28K, HTN27K, HTNS5S-2, and EHHNK5 ride-on power trowels.
- Bearing Support Integrity — A correctly seated flange housing keeps the rotor shaft centered and stable under the high cyclic loads of concrete finishing, preventing premature bearing wear and shaft misalignment.
- Operational Safety — A failed or cracked flange housing can allow rotor shaft movement during operation, creating unpredictable blade behavior on a ride-on trowel — replacing with a genuine OEM part restores correct shaft containment.
The bearing flange housing is a structural mounting component that locates and retains the rotor shaft bearing within the trowel's gearbox or rotor drive assembly. It holds the bearing in precise alignment so the rotor shaft transmits drive force evenly to the finishing blades without lateral movement or wobble. When the housing becomes worn, cracked, or damaged, the bearing loses its secure seat, leading to shaft play, accelerated bearing failure, vibration, and uneven blade pitch across the finishing pass.
