Multiquip 30352-02 Double Bearing Hayes - OEM Replacement Part for Trowels

The double bearing assembly is a critical component in the spider plate system of ride-on power trowels, supporting the trowel arm mechanism that enables smooth, fluid rotation during concrete finishing operations. This Hayes-manufactured bearing assembly maintains proper alignment and reduces friction between moving parts in the trowel's upper assembly, directly affecting finish quality and machine performance.

Bearing failure or excessive wear in this assembly can cause several operational issues including machine bouncing, uneven concrete swirls, rocking guard rings, and trowel arms with more than 1/8 inch of play. Regular inspection of bearing tightness should be performed by moving trowel arms up and down to check for excessive clearance. The bearing works in conjunction with bronze bushings and trowel arm components to maintain the critical alignment between the spider assembly and gearbox mounting system. When replacing bearings, verify that trowel arm straightness is within 0.005 inch (0.127mm) tolerance using a flat test surface and feeler gauge to ensure optimal performance.
