The AirTAC Airtac SC32 Standard Cylinder SC32X1250S is a genuine double-acting standard air cylinder with a Ø32mm bore and 1250mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X1250S is a double-acting tie-rod cylinder with a 32 mm bore and an extended 1250 mm non-standard stroke, delivering 402 N of push force at 0.5 MPa. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection without external brackets.
This model uses a 12 mm piston rod with M10x1.25 threads and PT1/8 ports. Its 21 mm adjustable air cushion decelerates the piston smoothly at each end. With a body length of 140 mm, the total extended length reaches approximately 1390 mm, making it suitable for long-reach actuation where sensor feedback is required.

The 1250 mm stroke moves light trays or components between distant stations on packaging lines, with the magnetic piston confirming full extension and retraction.
Applies 402 N at 0.5 MPa for holding parts in light assembly fixtures, where the -S magnet triggers a sensor to interlock the next machine cycle.
Operates diverters or stop gates on slim conveyors, using the tie-rod design for easy maintenance access and magnetic sensors for position verification.
Choose the SC32 bore for light-duty positioning and clamping tasks. If your force requirement exceeds 724 N at 0.9 MPa, step up to the SC40 bore, which provides 1130 N at the same pressure. For this 1250 mm stroke, which exceeds the standard maximum of 1000 mm for bore 32, it is a made-to-order item.
At this stroke length, the 12 mm rod is susceptible to bending under side loads. Always use an external linear guide or rod-alignment coupler to protect the rod bearing and seals. For direct replacement, match the 32 mm bore, 1250 mm stroke, PT1/8 port thread, basic mounting, and the -S magnet option.
Quick checklist
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N.
For a 1250 mm stroke with a 12 mm rod, side loading must be avoided. Install an external linear guide rail or rod-alignment coupler parallel to the cylinder to absorb transverse forces and prevent premature bearing wear.
