- Plastic injection molding machine ejectors
- CNC machine tool clamping mechanisms
- Food processing conveyor gate actuators
- Lithium battery production line handling
Installation tip:
Maintain 0.5-1mm alignment tolerance during mounting. For vertical installations exceeding 45° angle,
use the optional grease reservoir kit (GRK-40) to prevent upper seal dry-out.
