The AirTAC Airtac SC32 Standard Cylinder SC32X620 is a genuine double-acting standard air cylinder with a Ø32mm bore and 620mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X620 is a double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure). With a 32 mm bore and a 12 mm piston rod, it is built for light-to-medium pneumatic tasks where a compact body length of 140 mm (plus the 620 mm stroke) fits tight machine envelopes.
This 620 mm stroke exceeds the standard 1000 mm maximum for the 32 mm bore, making it a non-standard, made-to-order configuration. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, protecting end caps during high-cycle operation. Ports are PT1/8 with an M10x1.25 rod thread, and the default TPU seals cover a -20 to +70 °C working range.

The 620 mm stroke and 402 N push force at 0.5 MPa reliably actuate diverter gates on compact conveyor lines, handling lightweight packages with rapid cycle times.
Ideal for applying consistent tension to belts or webs in textile and printing machinery, where the long stroke maintains pressure over a wide adjustment range.
Powers linear transfer arms in sample handling systems, moving vials or microplates with the smooth, adjustable cushioning needed for delicate labware.
For applications needing more force, stepping up to the SC40 bore provides 628 N at 0.5 MPa, while the SC32 remains ideal where space and weight are primary constraints. At a 620 mm stroke, the 12 mm rod is susceptible to bending under side loads—always guide the load externally or use a guided cylinder if off-axis forces are present.
To ensure a drop-in replacement, match five key points: 32 mm bore, 620 mm stroke, PT1/8 port thread, basic (no) mounting, and the absence of a magnet. This SC32X620 is a direct swap only for another AirTAC SC32 tie-rod cylinder with the same specifications.
Quick checklist
At 0.7 MPa operating pressure, the SC32X620 produces a theoretical push force of 563 N. The pull force on the return stroke is 345 N at 0.5 MPa (confirm pull force at 0.7 MPa from the full datasheet).
For a 620 mm stroke on a 12 mm rod, side loading is a critical concern. Even small off-axis forces can cause rod bending or premature bearing wear. It is strongly recommended to use an external linear guide or ensure the load is perfectly axial to prevent damage.
