The AirTAC SC Standard Cylinders SC160X310SFA is a genuine double-acting standard air cylinder with a Ø160mm bore and 310mm stroke, PT3/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC160X310SFA is a heavy-duty tie-rod cylinder in AirTAC's SC single-rod double-acting range, sized at 160 mm bore with a 310 mm stroke. At 0.5 MPa it develops about 10053 N on extension and 9425 N on retraction, rising to 18095 N at the 0.9 MPa maximum operating pressure - a force class suited to presses, clamping fixtures and heavy actuation. The 40 mm hardened rod and 29 mm adjustable cushions give this big bore the strength and stroke-end control that demanding machinery needs.
This -SFA variant carries a built-in magnet, so CMSG, DMSG or EMSG sensors can clamp directly onto the barrel for end-of-stroke or mid-stroke signalling, plus an FA front rectangular flange (part code F-SC160FA) for rod-side panel or end mounting. Ports are PT3/8... correction: PT3/4, the rod thread is M36x2, and body length A is 239 mm, giving an extended length of roughly 549 mm. As a 125-250 mm bore model it is built to ISO 6430 class standards and runs at 30-500 mm/s.

With 14074 N at 0.7 MPa over a 310 mm stroke, the SC160X310SFA drives compact pressing, riveting and forming heads where tonne-class force is needed in a short working envelope.
The FA front flange bolts the cylinder to a machine end-face, while the built-in magnet feeds position signals to the PLC for interlocked clamping of large weldments and castings.
The 40 mm rod pushes and pulls heavy slides, gates and linkages at up to 18095 N at 0.9 MPa, with 29 mm adjustable cushions absorbing the momentum at each end of the 310 mm travel.
At this 160 mm bore you are already in the top force tier of the SC range; if your load needs less than the 982 N of a 50 mm bore at 0.5 MPa, step down rather than oversizing, and consider the 200 mm bore (15708 N at 0.5 MPa) only when you genuinely need over 15 kN. With a 310 mm stroke and a 40 mm rod, side loads or off-axis forces will bend the rod and wear the front bearing - use an external guide, or a guided cylinder, to keep the load aligned. Replacement matching is straightforward: confirm bore (160), stroke (310), port thread (PT here, or G for BSP parallel), the mounting accessory (FA flange, F-SC160FA) and the magnet option (-S) against your old cylinder.
Quick checklist
At 0.5 MPa the 160 mm bore delivers 10053 N extending and 9425 N retracting. At 0.7 MPa that rises to 14074 N, and at the 0.9 MPa maximum operating pressure it reaches 18095 N. Theoretical maximum force at 1.0 MPa is about 2050 kgf.
Yes - the -S suffix means a magnet is built into the piston, so CMSG, DMSG or EMSG reed or solid-state sensors clamp straight onto the barrel. For a like-for-like replacement, match bore (160), stroke (310), port thread (PT3/4, or specify G), the FA flange accessory (F-SC160FA) and the magnet option.
