Motor Brush & Bearing Replacement

Ensure your equipment operates at peak performance with our specialized Motor Brush and Bearing Replacement Services.

Regular maintenance of motor brushes and bearings is crucial for optimal performance and longevity. Test Tag Repair provides expert service to keep your machines running smoothly. We have the specialized equipment needed for proper bearing removal and installation using a hydraulic press - not hammered in.

New vs Worn Motor Brushes

Double K Airmax dryer brushes: New (top) vs Worn (bottom)

The image shows the difference between new motor brushes (top, with longer carbon blocks) and worn brushes (bottom, with significantly shorter carbon). When brushes wear down, they can cause sparking, reduced power, and eventually motor failure if not replaced.

Why Timely Brush Replacement Matters

Comparison of new commutator versus worn/damaged commutator showing arcing damage

Running a machine with worn brushes reduces the spring tension of the brush against the commutator. This reduced pressure increases damage from arcing between the brush and commutator surface.

Over time, the brushes may end up with uneven wear patterns. When this happens, even fitting new brushes won't help - they won't seat properly and won't last. At this point, the motor becomes a throwaway.

Don't wait until it's too late - have your motor brushes checked regularly to avoid costly motor replacement.
