About the Airtac SC32 Standard Cylinder SC32X640S
The SC32X640S is a double-acting single-rod pneumatic cylinder delivering 402 N of push force at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure). With a 32 mm bore and a 640 mm stroke, this unit is well-suited for medium-reach clamping, sorting, and material-transfer tasks where the stroke must exceed half a metre.
The built-in magnet (denoted by the -S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The 12 mm diameter piston rod features an M10x1.25 knuckle thread, and the adjustable air cushion (21 mm length) decelerates the piston smoothly at both ends of travel.

Where the Airtac SC32 Standard Cylinder SC32X640S Is Used
Long-Reach Part Transfer
The 640 mm stroke moves lightweight components between conveyor lanes or indexing stations. The built-in magnet confirms end-of-stroke with a barrel-mounted sensor.
Automated Sorting Gates
Actuates a diverter gate or flipper on a packaging line. The adjustable cushion softens the stop, protecting the gate mechanism from impact fatigue.
Test-Rig Linear Actuation
Provides a clean, repeatable 640 mm linear motion for life-cycle test fixtures. The M10x1.25 rod thread accepts standard rod-end accessories.
Is the Airtac SC32 Standard Cylinder SC32X640S the Right Cylinder?
For applications needing more push force at the same pressure, the 40 mm bore SC40 series provides 628 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, stepping down to a 25 mm stroke standard model reduces the extended length. At a 640 mm stroke, the unsupported rod length is significant; side loads or off-axis mounting can cause rod bearing wear and bending—consider an external guide rail or a guided cylinder if the load is not perfectly axial.
To replace an existing cylinder, match five points: 32 mm bore, 640 mm stroke, PT1/8 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration. The SC body length A is 140 mm, giving a total extended length of approximately 780 mm.
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 SC32X640S FAQ
At the standard 0.5 MPa operating pressure, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N.
Yes. The -S suffix indicates a built-in magnet. AirTAC CMSG (reed), DMSG, or EMSG (solid-state) sensors clamp onto the tie-rod barrel to detect piston position without additional brackets.
