The AirTAC Airtac SC40 Standard Cylinder SC40X210SCA is a genuine double-acting standard air cylinder with a Ø40mm bore and 210mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X210SCA is a double-acting pneumatic cylinder with a 40 mm bore and 210 mm stroke, delivering a push force of 628 N at 0.5 MPa. This model includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, combined with a rear single clevis (CA) mount for pivoting applications.
Its 16 mm diameter piston rod and PT1/4 port provide a robust connection for medium-duty automation tasks. The adjustable air cushion decelerates the piston smoothly over the final 21 mm of travel, protecting end caps. The body length A is 142 mm, making this genuine AirTAC tie-rod cylinder a compact choice where a shorter footprint than an ISO 15552 cylinder is required.

The 628 N push force reliably actuates diverter gates on packaging lines. The rear clevis mount allows the cylinder body to pivot as the gate swings, preventing rod binding.
Ideal for pneumatic clamping in CNC woodworking or light metalworking fixtures. The built-in magnet enables clamp-open and clamp-closed confirmation via barrel-mounted sensors.
Controls flapper doors on seed or fruit sorting chutes. The TPU seals handle standard temperatures from -20 to +70 °C, and the clevis mount simplifies integration into existing linkages.
For applications requiring higher force, stepping up to the 50 mm bore SC50 series provides 982 N of push force at the same 0.5 MPa pressure. If a lower force is sufficient, the 32 mm bore SC32 series offers 402 N.
This 210 mm stroke is within the standard range for the 40 mm bore (max 1200 mm). When replacing an existing cylinder, ensure a 5-point match: 40 mm bore, 210 mm stroke, PT1/4 port thread, rear clevis (CA) mounting accessory F-SC40CA, and the built-in magnet (-S) for sensor compatibility.
Quick checklist
At 0.5 MPa (5 bar), 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.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC tie-rod cylinder matching the 40 mm bore, 210 mm stroke, PT port, rear clevis mount, and built-in magnet.
