The AirTAC Airtac SC40 Standard Cylinder SC40X285 is a genuine double-acting standard air cylinder with a Ø40mm bore and 285mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X285 is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 285 mm stroke suit medium-force linear tasks where a compact body length is needed—the SC body is shorter than an ISO 15552 profile.
This model uses a 16 mm diameter piston rod with M12x1.25 threads and PT1/4 pneumatic ports. The adjustable air cushion (21 mm length) decelerates the piston quietly at end-of-stroke, reducing impact stress on the end caps and your machine frame.

The 285 mm stroke provides enough reach to push cartons off a conveyor line. The 628 N force at 0.5 MPa handles medium-weight packages reliably.
Apply consistent 1130 N clamping force at 0.9 MPa for CNC fixtures or assembly jigs. The adjustable cushion prevents part damage from hard end-of-stroke impacts.
Use the 528 N pull force at 0.5 MPa to retract a platen or tooling. The 16 mm rod and tie-rod construction provide rigidity for guided vertical lifts.
Choose the SC40 bore when your application needs roughly 628 N of push force at standard plant pressure. If you need more force, stepping up to the SC50 bore provides 982 N at 0.5 MPa with the same PT1/4 port size. For a 285 mm stroke, ensure the rod is not subjected to high side loads; long unsupported rods can bend. Use an external linear guide or a guided cylinder if side forces are present.
To replace an existing cylinder, match five points: 40 mm bore, 285 mm stroke, PT1/4 port thread, basic (no mounting accessory), and no magnet. This is a tie-rod cylinder and is dimensionally interchangeable only with another AirTAC SC40 of the same stroke and port type.
Quick checklist
At 0.5 MPa, push force is 628 N and pull force is 528 N. At the maximum operating pressure of 0.9 MPa, 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 body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552. Replace only with another AirTAC SC40 cylinder matching the 285 mm stroke and PT1/4 ports.
