- Material handling: Clamping fixtures
- Printing equipment: Paper feed mechanisms
- Food processing: Sanitary-grade compatible versions
Installation tips:
Allow 5mm minimum clearance around cylinder body for heat dissipation.
Use flexible couplings for rod-end connections to prevent side-loading.
For vertical mounting, specify magnetic piston version (SI50M) for position sensing.
