The AirTAC Airtac SC40 Standard Cylinder SC40X205 is a genuine double-acting standard air cylinder with a Ø40mm bore and 205mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X205 is a double-acting single-rod pneumatic cylinder with a 40 mm bore and a non-standard 205 mm stroke, built for applications needing a specific extended length beyond the standard catalogue range. With a 16 mm diameter piston rod and PT1/4 ports, it generates 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa, providing a solid mid-range thrust for clamping, pressing, and material handling tasks.
This tie-rod cylinder features an adjustable air cushion (21 mm cushion length) to decelerate the piston smoothly at both ends, reducing impact noise and wear. Its compact body length of 142 mm plus the 205 mm stroke gives a total extended dimension of approximately 347 mm, making it suitable for installations where space is constrained but a longer working travel is required.

The 205 mm stroke and 628 N push force at 0.5 MPa reliably divert cartons or trays on a packaging line, with adjustable cushioning to protect the product from impact damage.
Delivers up to 1130 N of clamping force at 0.9 MPa for holding workpieces during drilling or milling, where the specific 205 mm extension fits a custom jig layout.
Provides repeatable linear motion for endurance testing of small mechanical components, using the non-standard stroke to match the exact displacement required by the test protocol.
Choose the SC40X205 when you need a 40 mm bore force class with a precise 205 mm stroke—note this is a non-standard stroke, so it is a made-to-order item. If your load demands more force, step up to the SC50 bore (982 N at 0.5 MPa); if you need less, the SC32 delivers 402 N at 0.5 MPa. For strokes of 300 mm or more, consider an external guide or a guided cylinder to protect the 16 mm rod from bending under side loads.
For replacement, match these five points exactly: 40 mm bore, 205 mm stroke, PT1/4 port thread, basic (no mounting accessory), and no built-in magnet. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa operating pressure, the SC40X205 produces 879 N of push force. The theoretical maximum force at 1.0 MPa is 128 kgf, but the recommended operating range is 0.15–1.0 MPa.
No. The AirTAC SC series is a tie-rod cylinder and is shorter in overall length than an ISO 15552 cylinder of the same bore and stroke. The mounting dimensions and body length are different, so it is not a drop-in replacement. Only use it to replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port, mounting, and magnet options.
