About the Airtac SC100 Standard Cylinder SC100X40S
The SC100X40S is a double-acting tie-rod cylinder delivering 3927 N of push force at 0.5 MPa, ideal for short-throw clamping and pressing tasks. Its 100 mm bore houses a 25 mm diameter piston rod with PT1/2 ports, and the 40 mm stroke keeps cycle times fast in compact automation cells.
A built-in magnet (suffix -S) allows CMSG, DMSG, or EMSG sensors to mount directly on the barrel for reliable end-of-stroke detection. The cylinder operates on filtered air from 0.15 to 1.0 MPa and includes an adjustable air cushion to decelerate the piston smoothly.

Where the Airtac SC100 Standard Cylinder SC100X40S Is Used
Short-Stroke Clamping
Delivers 3927 N at 0.5 MPa to hold workpieces securely in CNC fixtures and welding jigs, with magnetic sensors confirming clamp position.
Automated Press-Fit Assembly
The 40 mm stroke and high force insert bearings, bushings, or pins with controlled speed, while the adjustable cushion protects parts from impact.
Part Stops & Diverters
Quick-extending rod stops or diverts packages on conveyors. The -S magnet enables sensor feedback to the line controller for every cycle.
Is the Airtac SC100 Standard Cylinder SC100X40S the Right Cylinder?
For higher force, step up to the SC125 bore (6136 N at 0.5 MPa); for lighter, faster actuation, the SC80 bore provides 2513 N. The short 40 mm stroke is well within standard limits, but always align the rod axis with the load to prevent side-load wear. When replacing, match five points: 100 mm bore, 40 mm stroke, PT port thread, the -S magnet option for sensor compatibility, and basic mounting style.
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 SC100 Standard Cylinder SC100X40S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
Yes. The -S suffix indicates a built-in magnet, so you can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without additional brackets.
