The AirTAC Airtac SC40 Standard Cylinder SC40X600STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 600mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X600STC is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore and 600 mm stroke, this model features a 16 mm diameter piston rod and a 21 mm adjustable air cushion for smooth end-of-stroke deceleration.
This variant includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC suffix) supplied with the TCM1 bracket (F-SC40TC) for pivoting applications. The total extended body length is approximately 742 mm, making it a compact tie-rod solution for medium-force, mid-stroke automation tasks.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Operates diverter gates on conveyor systems where the 600 mm stroke provides full gate travel and the centre trunnion mount allows the cylinder to pivot as it actuates.
Delivers 1130 N of clamping force at 0.9 MPa for medium-duty CNC fixtures and welding jigs, with magnetic sensors confirming clamp/unclamp position.
Suited for pivoting linkages on sorting or planting machinery where the trunnion mount absorbs angular movement and the TPU seals handle standard outdoor temperatures.
Choose the SC40 bore for applications needing around 628 N of force at standard plant pressure. If your load requires more thrust, step up to the SC50 bore which provides 982 N at 0.5 MPa. For strokes of 300 mm or longer, like this 600 mm model, ensure the rod is protected from side loads—an external guide or guided cylinder is recommended to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, match all five critical points: 40 mm bore, 600 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile and is not a drop-in replacement for ISO 15552 actuators.
Quick checklist
At 0.5 MPa the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 actuators. Use it to replace another AirTAC SC40 tie-rod cylinder with matching port thread, mounting, and magnet option.
