About the Airtac SC40 Standard Cylinder SC40X100CB
The SC40X100CB is a 40 mm bore, 100 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 628 N of push force at 0.5 MPa. It features a 16 mm diameter piston rod with M12x1.25 male threads and an adjustable air cushion length of 21 mm at each end, providing reliable end-of-stroke deceleration.
This model is configured with a rear double clevis (CB) mounting, part F-SC40CB, which allows the cylinder body to pivot during operation, ideal for applications where the load follows an arc. The standard PT1/4 port and TPU seals suit a wide operating temperature range of -20 to +70 °C.

Where the Airtac SC40 Standard Cylinder SC40X100CB Is Used
Agricultural Machinery
Actuates chutes, gates, and levers on harvesters and planters where a pivoting cylinder mount (CB clevis) is needed to follow the linkage arc, providing 628 N of push force.
Conveyor Diverters
Pushes packages or materials off a main conveyor line. The 100 mm stroke offers a clean, full extension, and the rear clevis mount absorbs any minor misalignment in the diverter arm.
Clamping Fixtures
Provides consistent 628 N clamping force in welding or assembly jigs. The double clevis mount allows the cylinder to swing clear for part loading and unloading.
Is the Airtac SC40 Standard Cylinder SC40X100CB the Right Cylinder?
The SC40 delivers 628 N at 0.5 MPa. If your application requires more force, stepping up to the 50 mm bore SC50 provides 982 N at the same pressure. For lighter, more compact needs, the SC32 offers 402 N. This 100 mm stroke is well within the 1200 mm maximum standard stroke for the 40 bore.
For a drop-in replacement, match five key points: 40 mm bore, 100 mm stroke, PT1/4 port thread, CB rear double clevis mounting, and the standard non-magnetic piston. This ensures full interchangeability with an existing AirTAC SC40X100CB cylinder.
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 SC40X100CB 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.
Yes, if the original is an AirTAC SC tie-rod cylinder. Verify the bore (40 mm), stroke (100 mm), port thread (PT1/4), and mounting (CB rear double clevis). This model has no magnet, so ensure your application does not require magnetic piston sensing.
