The AirTAC Airtac JSI Series Standard Cylinder JSI32X16 is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 16mm stroke, G1/8 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.
Delivering 402 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder fits where space is tight. As a JIS-standard profile unit, it occupies a shorter envelope than an ISO 15552 cylinder of the same bore. The extruded hard-anodized aluminum barrel removes external rods to resist wear, while a two-way piston seal retains grease for low-friction life.
This specific 16 mm stroke is a non-standard, made-to-order length for very short travel. Because it lacks the -S suffix, this SKU cannot host CMSE or DMSE sensors. Plan for roughly 241 N of real work at 0.5 MPa, which equates to lifting about 20 kg vertically with a 2:1 margin. The unit uses a G1/8 port and an M10x1.25 rod thread.

Ideal for small part clamping on electronics assembly lines where a 16 mm travel and 402 N force secure delicate PCBs.
Drives short-stroke sorter flaps in packaging machinery, fitting into compact spaces where ISO 15552 cylinders are too long.
Handles light-duty pin pressing tasks in automated fixture stations, lifting roughly 20 kg vertically with a 2:1 margin.
Since this is the smallest JSI bore, the next step up is the 40 mm version, which raises push force to 628 N at 0.5 MPa. For ultra-short travel like this 16 mm made-to-order stroke, side-load risks are minimal, but ensure the load is axially aligned. Without the -S magnet option, position sensing is unavailable on this SKU. Note that air loss or a centered valve will cause the piston to drift; the adjustable 20 mm cushions only decelerate the stroke end, so add a pilot-operated check valve if you must hold a load.
Quick checklist
This 32 mm bore cylinder features a G1/8 port. It generates 402 N push and 345 N pull at 0.5 MPa, 563 N push and 483 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
No. Because this SKU lacks the -S suffix, it has no magnet and cannot take CMSE or DMSE switches. You would need the -S variant for sensing. It is also a JIS profile cylinder, meaning it is shorter and more compact than a same-bore ISO 15552 unit.
