The AirTAC Airtac SC40 Standard Cylinder SC40X610S is a genuine double-acting standard air cylinder with a Ø40mm bore and 610mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X610S is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore and a 610 mm stroke, it is well-suited for medium-reach material handling or pressing tasks. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This model uses a 16 mm diameter piston rod with an M12x1.25 rod thread and PT1/4 ports. The body length A is 142 mm, giving a total extended length of approximately 752 mm. It includes a 21 mm adjustable air cushion to decelerate the piston smoothly, reducing impact noise and wear at the end of each cycle.

The 610 mm stroke moves components between conveyor lanes or workstations. The magnet enables sensor confirmation at both ends of travel.
628 N at 0.5 MPa provides consistent force for gluing, staking, or light assembly presses. The 21 mm cushion absorbs impact for quieter operation.
Operates diverters or gates on packaging lines. The -S magnet simplifies integration with reed or solid-state sensors for PLC feedback.
For applications needing more force, stepping up to the 50 mm bore provides 982 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 32 mm bore offers 402 N. At a 610 mm stroke, ensure the rod is supported against side loads; consider an external guide or a guided cylinder if the load is not purely axial, as a long unsupported rod can bend under lateral force.
To match this cylinder for replacement, verify five points: 40 mm bore, 610 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic tie-rod mounting style. The SC is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC cylinders with these exact specifications.
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. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder. It is not dimensionally interchangeable. Replace it only with another AirTAC SC40 cylinder matching the 610 mm stroke, PT1/4 ports, and -S magnet option.
