The AirTAC Airtac SC40 Standard Cylinder SC40X30TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 30mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X30TC is a double-acting tie-rod cylinder with a 40 mm bore and a compact 30 mm stroke, delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration in a short-stroke package, with a body length A of just 142 mm.
This model is configured with a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC40TC), allowing the cylinder to pivot freely for swinging or articulating loads. The standard PT1/4 port and TPU seals suit general industrial air service from -20 to +70 °C.

The centre trunnion mount lets this 30 mm stroke cylinder pivot to actuate small diverter gates on packaging conveyors.
Delivers 628 N at 0.5 MPa for light-duty pneumatic clamping in assembly jigs, with a short stroke for fast cycle times.
Ideal for driving short-throw linkages on processing equipment where the cylinder body must swing through an arc.
Choose the SC40 bore for push forces up to 1130 N at 0.9 MPa; if your load requires more force, step up to the SC50 (982 N at 0.5 MPa). For a direct replacement, match the 40 mm bore, 30 mm stroke, PT1/4 port thread, centre trunnion mounting, and confirm the magnet option is not required.
At this short 30 mm stroke, rod bending is not a concern, but ensure the trunnion pivot axis is aligned to avoid binding.
Quick checklist
At 0.5 MPa it produces 628 N extending and 528 N retracting. At the maximum operating pressure of 0.9 MPa, the extending force is 1130 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC tie-rod cylinder of the same bore, stroke, and mounting configuration.
