What are the consequences of excessive bushing wear?

Excessive bushing wear triggers a chain reaction, severely impacting equipment performance and lifespan.

Visually, it manifests as pronounced wear marks (scratches, pitting, metal flaking), deformation or cracking, and contaminant adhesion. During operation, it produces abnormal noises (squeaking, grinding, knocking), heightened vibration, and abnormal temperature increases, leading to performance degradation such as reduced precision, increased leakage, and higher energy consumption. These anomalies further exacerbate wear, creating a vicious cycle.

In terms of consequences, excessive wear compromises machine quality, shortens equipment lifespan, and impairs core component functionality; reduces machine efficiency, consumes energy, and increases frictional resistance; diminishes reliability, creating safety hazards, and may cause sudden failures. Additionally, it leads to poorer surface finish on machined parts, compromises dimensional accuracy, and may damage other high-value components such as spindle taper bores and bearing housings, substantially increasing maintenance costs. In automotive and similar equipment, it may also trigger issues such as half-shaft fractures, abnormal tyre wear, and oil leaks.

Therefore, upon detecting any signs of sleeve wear, prompt inspection and replacement are essential to prevent more severe consequences.
