About the Airtac SC32 Standard Cylinder SC32X40S
The AirTAC SC32X40S is a double-acting single-rod tie-rod cylinder delivering 402 N push force at 0.5 MPa (724 N at 0.9 MPa). Its 40 mm stroke suits short linear transfer and clamping operations in compact automation cells.
This -S variant includes a built-in magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to mount directly on the barrel for contactless position sensing. The 12 mm diameter rod, PT1/8 ports, and 21 mm adjustable air cushion provide reliable deceleration in a body length of just 140 mm (A dimension).

Where the Airtac SC32 Standard Cylinder SC32X40S Is Used
Compact Part Ejection
Short 40 mm stroke ejects small plastic or metal components from injection molds or stamping dies, with magnetic sensors confirming full retraction.
Miniature Diverter Gate
Operates a small diverter flap on a conveyor line. The 402 N push force at 0.5 MPa is ample for lightweight package sorting.
Lab Automation Clamping
Clamps test tubes or microplates in analytical instruments. The built-in magnet enables clean, non-contact position feedback via DMSG sensors.
Is the Airtac SC32 Standard Cylinder SC32X40S the Right Cylinder?
Choose the SC32 bore for light push forces up to 724 N. If your load exceeds this, step up to the SC40 (628 N at 0.5 MPa). For this 40 mm stroke, side load is minimal, but always align the rod with the load axis to prevent bending.
To match this cylinder in an existing installation, verify five points: 32 mm bore, 40 mm stroke, PT1/8 ports, the built-in magnet (-S) for sensor mounting, and the basic (no bracket) mounting configuration.
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.
Airtac SC32 Standard Cylinder SC32X40S FAQ
At 0.5 MPa the push force is 402 N and pull force is 345 N. At the maximum operating pressure of 0.9 MPa, push force reaches 724 N. The theoretical maximum at 1.0 MPa is 82 kgf.
Yes. The -S suffix denotes a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip directly onto the barrel groove for end-of-stroke detection.
