Motion System Parts
Components that move and synchronize the machine's axes — where wear shows up as drift, backlash and, eventually, servo alarms.
Component families
Typical Components
The exact configuration depends on your machine model. Your spare parts documentation — issued per machine — lists the qualified items for your serial number.
| Component | Role in the system | Condition to watch |
|---|---|---|
| Drive & timing belts | Transfer motion between shafts | Glazing, cracks, tension |
| Bearings | Support rotating elements | Roughness, temperature outliers |
| Couplings | Connect shafts and servo axes | Play, alignment |
| Servo motors & drives | Provide controlled motion | Serviced per Path Pack documentation |
| Gearboxes (where fitted) | Adapt speed and torque | Noise, leakage — per manual |
| Linear guides & slides | Guide moving assemblies | Contamination, smoothness |
Condition & Replacement
Condition-based — per your machine manual.
- Belts and bearings are covered by the weekly maintenance pass — tension, condition and running smoothness.
- Backlash found at couplings or linkages is a support case, not an adjustment to work around.
- Servo motors, drives and encoders are not self-serviced — they are handled per Path Pack documentation.
Technical Note
Replacement criteria are defined per machine in your Path Pack documentation. Related troubleshooting: Servo Alarms and Inconsistent Package Length; the weekly routine lives in Weekly Maintenance.
Identifying a Motion Part
Belts and bearings carry type markings.
- Machine model and serial number
- Type marking on the belt or bearing, photographed
- Position on the machine (axis or assembly)
