Multiquip 2619 HD & HRT Bearing Kit - OEM Replacement Part for Walk-Behind Trowels

This bearing kit ensures smooth operation of the spider assembly and vertical output shaft on Multiquip walk-behind trowels. The bearing system supports the gearbox output shaft that connects to the spider hub, which extends to hold the four radially-mounted trowel blades. Failed bearings create excessive vibration, unusual noise during operation, and can lead to premature wear on the spider arms and blade mounting points.

The HDA series walk-behind trowels operate at rotor speeds from 35 to 225 rpm with an operating weight of 327 lb, placing significant stress on the bearing assembly during floating and finishing operations. Regular inspection of bearings is critical during routine maintenance checks, particularly when inspecting blade wear patterns and V-belt condition. Worn bearings often manifest as uneven blade contact or difficulty maintaining consistent pitch across all four spider arms.

Compatible with the following Multiquip models:

• HDA-SERIES Walk-Behind Trowels
• JWN24HTCSL
