The AirTAC Airtac SC40 Standard Cylinder SC40X35 is a genuine double-acting standard air cylinder with a Ø40mm bore and 35mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X35 is a compact-stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. With a 40 mm bore and 35 mm stroke, it produces a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa, driven by a 16 mm diameter piston rod.
This model uses the standard TPU seal for a working temperature range of -20 to +70 °C and features a PT1/4 pneumatic port. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, while the total body length A of 142 mm plus the 35 mm stroke keeps the envelope tight for space-constrained installations.

The 35 mm stroke and 628 N push force at 0.5 MPa make the SC40X35 ideal for pneumatic clamping fixtures in CNC machining or assembly jigs where rapid, repeatable part holding is needed.
Delivers a crisp 35 mm linear motion to eject small components from a conveyor or actuate a diverter gate on a packaging line, with the 16 mm rod providing good resistance to impact loads.
With a maximum theoretical force of 128 kgf at 1.0 MPa, this cylinder suits light press-fit operations for bearings, bushings, or pins in benchtop automation cells.
For applications needing slightly more force, stepping up to the SC50 bore delivers 982 N at 0.5 MPa. If a lower profile is required, the SC32 bore provides 402 N at the same pressure. Always match replacement cylinders on five points: bore (40 mm), stroke (35 mm), port thread (PT1/4), mounting style (basic), and magnet option (none on this model).
This short 35 mm stroke does not typically introduce rod-bearing side-load concerns, but any off-axis load should still be managed with an external linear guide to protect the rod bearing and piston seals from uneven wear.
Quick checklist
At 0.7 MPa operating pressure, the SC40X35 generates a push force of 879 N and a pull force of 528 N (retraction force is lower due to the rod area). The maximum push force at 0.9 MPa is 1130 N.
Not directly. This specific model code (SC40X35) does not include the -S magnet suffix, so the piston does not carry a magnetic ring. To use CMSG/DMSG/EMSG sensors, order the SC40X35-S variant which has a built-in magnet. The standard SC40X35 requires external limit switches for position sensing.
