About the Airtac SC40 Standard Cylinder SC40X100CA
The SC40X100CA is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 100 mm stroke. It generates a push force of 628 N at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa, making it suitable for medium-duty clamping and pressing tasks.
This model features a 16 mm diameter piston rod with an M12x1.25 rod thread and a rear single clevis (CA) mount, part code F-SC40CA, allowing the cylinder to pivot during operation. The body length A is 142 mm, and with the 100 mm stroke, the total extended length is 242 mm. It uses PT1/4 ports and includes an adjustable air cushion of 21 mm to decelerate the piston quietly.

Where the Airtac SC40 Standard Cylinder SC40X100CA Is Used
Clamping Fixtures
Provides 628 N of clamping force at 0.5 MPa for securing parts during machining or assembly, with the rear clevis allowing the cylinder body to self-align.
Part Diverter Gates
The 100 mm stroke and pivoting CA mount are well-suited for actuating diverter gates on conveyor lines, directing products between lanes with a consistent 40 mm bore force.
Agricultural Implement Control
Operates linkage mechanisms on small agricultural equipment, where the rear clevis mount handles the oscillating motion and the TPU seals perform reliably from -20 to +70°C.
Is the Airtac SC40 Standard Cylinder SC40X100CA the Right Cylinder?
For applications requiring more force, the 50 mm bore SC50 series provides 982 N of push force at 0.5 MPa, while the 32 mm bore SC32 series offers a more compact option with 402 N. The CA rear clevis mount is ideal for pivoting applications, but ensure the pivot pin is aligned to prevent side loading on the rod bearing.
When replacing an existing cylinder, match these five points for a direct fit: 40 mm bore, 100 mm stroke, PT1/4 port thread, rear single clevis (CA) mounting, and the absence of a built-in magnet. This cylinder does not include a magnet, so external sensors like reed switches cannot be directly mounted on the barrel.
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 SC40 Standard Cylinder SC40X100CA FAQ
At the standard operating pressure of 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
No, this specific model code SC40X100CA does not include the -S magnet option. The piston lacks a built-in magnetic ring, so CMSG/DMSG/EMSG sensors cannot be used. For sensor compatibility, order the SC40X100CAS variant.
