The AirTAC Airtac SC40 Standard Cylinder SC40X700SN is a genuine double-acting standard air cylinder with a Ø40mm bore and 700mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X700SN is a double-acting pneumatic cylinder with a 40 mm bore and 700 mm stroke, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-stroke applications, making it suitable for sorting gates and material transfer systems.
This model features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke position feedback without external brackets. The NBR seal (-N suffix) offers reliable performance in standard temperature environments, and the PT1/4 port thread ensures straightforward pneumatic connections.

The 700 mm stroke and 628 N push force at 0.5 MPa efficiently actuate diverter gates on conveyor lines, routing packages or components between lanes with integrated sensor feedback for cycle confirmation.
With a built-in magnet for position sensing, this cylinder is ideal for sorting mechanisms where the controller must verify full extension and retraction before initiating the next sequence.
The 1130 N maximum thrust at 0.9 MPa provides ample force for pushing boxes or trays onto a pallet layer, while the 700 mm stroke covers the width of a standard pallet station.
The SC40 bore generates 628 N of push force at 0.5 MPa. If your application requires more force, stepping up to the SC50 bore provides 982 N at the same pressure. For lower force needs, the SC32 bore delivers 402 N. Always match replacement cylinders across five points: bore, stroke, port thread (PT), mounting accessory, and magnet option (-S).
With a 700 mm stroke, the 16 mm rod is subject to bending under side loads. For this stroke length, consider an external linear guide or a guided cylinder configuration to protect the rod bearing and ensure consistent, long-term operation.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
Match five key specifications: 40 mm bore, 700 mm stroke, PT1/4 port thread, basic mounting (no bracket), and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is a direct replacement for another AirTAC SC40 of the same configuration, but it is not dimensionally interchangeable with ISO 15552 profile cylinders.
