A spacer is a precision-dimensioned component used to maintain the correct gap, alignment, or load distribution between two adjacent parts within an assembly. In a walk-behind power trowel, spacers are commonly found in the blade and rotor assembly, where they ensure each rotating component sits at the correct position relative to its neighbors. When a spacer wears, deforms, or is missing, it can cause uneven blade contact with the concrete surface, increased vibration, premature bearing wear, and a compromised finish — making timely replacement essential to consistent trowel performance.
