The Multiquip 21441 Bearing 2.9375" I.D. 4.527" O.D. is a genuine OEM component designed for CA, CS, and JS series walk-behind power trowels, including CA-4-4H, CA4HM, CA4.4HM, CA4HC, CA5BC, CS24H55E, JS36, and JS30H55DE models. As a direct Multiquip OEM part, 21441 is manufactured to the same dimensional and load specifications as the original, ensuring a correct drop-in fit within the trowel's rotating assembly. DHS Equipment supplies this part directly, so you can order with confidence knowing you're getting the right bearing for your machine.
Key Features
- Dimensionally Exact OEM Specification — 2.9375" inner diameter and 4.527" outer diameter match the original bearing seat dimensions precisely, ensuring correct seating without modification.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, this bearing meets the load ratings and tolerance grades specified for walk-behind trowel drive assemblies.
- Broad CA, CS, and JS Series Compatibility — Confirmed fitment across CA-4-4H, CA4HM, CA4.4HM, CA4HC, CA5BC, CS24H55E, JS36, and JS30H55DE models.
- Smooth Blade Rotation Under Load — A correctly rated bearing keeps the trowel's rotor spinning true and steady; a worn bearing introduces wobble, vibration, and uneven blade contact on the slab.
- Direct Replacement Installation — Installs into the existing housing without adapters, maintaining the correct shaft-to-housing relationship for proper blade pitch adjustment.
The bearing in a walk-behind power trowel supports the main rotor shaft or gearbox assembly, carrying the radial and axial loads generated as the blades work across freshly poured concrete. It allows the rotating components to spin freely and concentrically while holding everything in precise alignment. When this bearing wears or fails, operators typically notice increased vibration, noise from the rotor assembly, or uneven blade contact — all of which degrade the quality of the finished surface and can accelerate wear on surrounding components.
