Multiquip 21047 Bearing Seal Kit

The Multiquip 21047 Bearing Seal Kit is a genuine OEM replacement designed for Whiteman walk-behind power trowels including the J3036H55, B46, CA4HM, CA4HC, CA5BC, BS90C, BH11C, BH90C, JS60C, JH90C, JH55C, J36E2, and J36-M30 series, as well as international models CS24H55E, BS46H11, BS46H90, JS36H90, JS36H55, and CA-4-4H. As a genuine OEM component sourced directly through Multiquip, part 21047 is manufactured to the same specifications as the original hardware installed at the factory. This kit bundles the bearing and seal components together, simplifying the service process and ensuring every critical rotating-assembly component is replaced as a matched set. Confirm your model code against the fitment list above before ordering to ensure correct application.

Key Features

• Genuine OEM Bearing and Seal Precision — Manufactured to original tolerancing specifications, ensuring correct load ratings and seal compression for the trowel gearbox assembly.
• Complete Kit Format — Bearing and seal components are packaged together as a matched set, so all wear items in the rotating assembly are renewed in a single service event.
• Broad Whiteman and International Trowel Fitment — Confirmed for J3036H55, B46, CA4HM, BS90C, BH11C, JS60C, JH90C, J36-M30, CS24H55E, BS46H11, JS36H90, CA-4-4H, and additional models in the Whiteman walk-behind power trowel lineup.
• Restored Blade-Pitch Control — A worn or failed bearing in the trowel spider assembly causes imprecise blade pitch, uneven finishing passes, and accelerated wear on surrounding components; replacing with a correctly rated kit restores smooth, consistent blade adjustment.
• Seal Integrity Prevents Contamination — The included seal keeps grease in and abrasive concrete slurry out of the bearing housing — critical on a machine that operates directly over wet concrete.

The bearing and seal in a walk-behind power trowel work together inside the spider or gearbox assembly to support the rotating blade shaft and keep the lubricated internals isolated from the surrounding environment. The bearing carries the radial and axial loads generated as the trowel blades spin and pitch across the concrete surface, while the seal prevents grease migration outward and blocks fine concrete dust and moisture from entering the housing. When either component wears, operators typically notice increased vibration, stiff or uneven blade-pitch adjustment, or visible grease leakage around the blade assembly — all of which compromise finish quality and accelerate damage to adjacent components if left unaddressed.
