Where the Airtac SAI32 Standard Cylinder SAI32X250SN Is Used
Package Diverting
Extends 250 mm to push small cartons off a conveyor line, utilizing the 402 N push force at 0.5 MPa to handle light packaging materials reliably.
Small Part Ejection
Ejects lightweight molded parts from a machining center. The integrated magnet allows DMSE sensors to confirm ejection completion.
Drawer Actuation
Opens and closes automated storage drawers. The NBR seals ensure consistent operation across typical factory temperature ranges.
Is the Airtac SAI32 Standard Cylinder SAI32X250SN the Right Cylinder?
Choose this 32 mm bore when your application requires roughly 400 N of push force at 0.5 MPa. If your task demands less than 300 N, stepping down to a smaller bore is advisable, while loads exceeding 600 N would be better served by the 40 mm bore which outputs 628 N at the same pressure.
Because the 250 mm stroke is substantial for a 32 mm bore, avoid mounting heavy loads directly to the rod. Unsupported rods of this length can bend under side loads, so utilize an external guide rail or select a guided cylinder to prevent premature rod-bearing wear. If the machinery loses air pressure, this standard cylinder cannot hold its load; integrate a SAIL locking variant or external pilot check valve for fail-safe position holding. Replacement mounting is simplified via the ISO 15552 interface, matching the 32 mm bore, 250 mm stroke, G1/8 PT port, and compatible FA flange or LB foot accessories.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
