- PCB handling robots in electronics assembly
- Dosing valve actuators in medical analyzers
- Paper feed mechanisms in high-speed printers
- Clamping units in micro-injection molding
- Positioning stages in optical alignment systems
- Use alignment jig AKM-20F during mounting to ensure parallelism (≤0.1mm/m)
- Maintain 0.5-1.0mm end play when connecting to guided mechanisms
- For vertical mounting, install air exhaust mist separator APS-4M to prevent lubricant drain
