The Multiquip 11138 P-Block Bearing Housing is a genuine OEM component designed for HTN, HHN, JWN, and JTNS series ride-on power trowels, as well as SP series flat saws. This part is sourced directly through Multiquip's OEM supply chain, ensuring it matches the original specification for each compatible model. Compatible units include HTN28K, HTN27K, HHN34TVD, HHN31V, JWN24HTCSL, JTNSW24HTCSL, JTNSW20HTCSL, JTNSW20, JTNS20, HTNS5S-2, HHNG5, EHHNK5, SP118, SP1E16A, SP1CE13H18, and JTO-series machines. Sourcing the correct housing ensures the bearing assembly seats and retains properly, maintaining blade rotor alignment and overall trowel performance.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the bearing bore geometry and mounting interface match the factory housing exactly.
- Direct-Fit Installation — Mounts using the same bolt pattern and bearing seat dimensions as the original, allowing straightforward removal and reinstallation without modification.
- Broad Model Coverage — Fits HTN28K, HTN27K, HHN34TVD, HHN31V, JWN24HTCSL, JTNSW20, JTNS20, SP118, SP1E16A, SP1CE13H18, and additional HTN, HHN, JTNS, and SP series equipment.
- Bearing Retention Integrity — A properly seated P-block housing prevents bearing migration and rotor wobble, keeping blade pitch control precise and consistent during finishing passes.
- Verified Part Number — Cross-reference part number 11138 against your model's parts manual to confirm application before installation.
The P-Block Bearing Housing is a structural mounting component that locates and retains the rotor shaft bearing in ride-on power trowels and walk-behind finishing equipment. It keeps the bearing correctly positioned within the drive assembly so that the rotor shaft runs true, maintaining consistent blade angle and rotational balance. When this housing cracks, wears at the bore, or loses its seating integrity, bearing movement increases, leading to rotor vibration, uneven blade contact with the concrete surface, and accelerated wear on surrounding drivetrain components.
