Multiquip 11149 Ball Bearing SB-204-12

The Multiquip 11149 Ball Bearing SB-204-12 is a genuine OEM replacement bearing designed for a wide range of Multiquip and Whiteman ride-on power trowels and Street Pro flat saws. This includes mechanical trowel models such as the HTN27K, HTN28K, HHN31V, HHN34TVD, JWN24HTCSL, and the JTO series, as well as SP-series flat saws including the SP118, SP1E16A, and SP1CE13H18. As an authentic Multiquip OEM component, the 11149 is manufactured to the original design specification, so you can install it with confidence knowing the fit and function match what came off the production line. Verify your model code against the fitment list before ordering to confirm compatibility.

Key Features

• Genuine OEM Bearing Grade — Manufactured to the original radial load and dimensional tolerances specified for Multiquip trowel and saw driveline applications, ensuring consistent rotation under sustained operating loads.
• Drop-In Installation — Matches the original SB-204-12 bore, outer diameter, and shoulder dimensions, so the bearing seats correctly in its housing without alteration to surrounding components.
• Broad Fitment Across Trowel and Saw Families — Compatible with HTN, HHN, and JWN mechanical ride-on trowel models as well as SP-series flat saws, covering a wide share of the Multiquip and Whiteman lineup with a single part number.
• Supports Smooth Blade and Drive Rotation — A properly functioning bearing keeps rotating assemblies aligned and friction-free; a worn bearing causes vibration, premature component wear, and loss of trowel blade control or saw drive efficiency.
• Driveline Safety Assurance — Bearings in trowel rotor and saw drive positions are load-bearing safety components; using a correctly rated OEM bearing helps prevent unexpected driveline failure during operation.

A ball bearing is a precision rolling-element component that supports rotating shafts and spindles while minimizing friction between moving parts. In ride-on power trowels, bearings are found in the rotor assembly and blade drive system, where they carry both radial and thrust loads generated during concrete finishing. In flat saws, they support the blade drive shaft under high rotational stress. When a bearing wears, develops flat spots, or loses its lubricant seal, the result is increased vibration, heat buildup, shaft misalignment, and eventual seizure — all of which interrupt work and can damage surrounding components. Replacing a worn bearing promptly with the correct OEM-spec part restores proper rotating clearances and protects the rest of the driveline.
