The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X160-30 is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 160mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ80X160-30 pairs an 80 mm bore with a 160 mm stroke and a 30 mm trim window. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N on the extend stroke at 0.7 MPa. The external stop screw shortens the extend stroke on site anywhere within the ordered 30 mm window, so the same cylinder serves 130-160 mm stroke positions without reordering. Its hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into presses, gantries and machine guards where a full-length body simply will not fit.
The S45C hard-chrome plated 20 mm rod resists scoring in high-cycle service, and the fixed TPU bumper at each end absorbs end-of-stroke shock. FA flange and LB foot mounts plus I and Y rod knuckles bolt to the standard ISO 21287 face, and the optional -S magnet code enables CMSE or DMSE switches for end-position sensing.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 2356 N |
| 0.7 MPa | 3299 N |
| Max (@1.0 MPa) | 481 kgf |
ACEJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

|---|---|
| 80 | Bore size in mm. |
| ×160 | Stroke length in mm. |
| -30 | Adjustable stroke window (mm the extend stroke can be shortened on site). |

ACE-family variants: ACE (double acting), ASE / ATE (single acting push / pull), ACED (double rod), ACEJ (double rod, adjustable stroke), TACE / TACED (non-rotating twin-guide yoke). Mounting accessories: FA / FB flange, LB foot, CA / CB clevis, CR, SDB pivot, FTC; plus I and Y knuckles. Thread PT (blank) / G.
Clamps carton stacks against a strapper head with about 1500 N of usable force at 0.5 MPa; the short ISO 21287 body fits the tight frame where an ISO 15552 profile cylinder is too long.
Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the rod still drifts if air is lost; use a separate valve or clamp for load holding. Order the -S code if you need CMSE / DMSE switch positions, and choose FA flange or LB foot mounting to match your fixture plate.
Quick checklist
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push rises to 3518.6 N and pull to 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: an external stop screw trims the 160 mm extend stroke down to as little as 130 mm, so you set the exact end position on site without reordering. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a fixed TPU bumper at both ends.
The hard-anodized aluminium ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow guards and tight jig plates. FA flange, LB foot and FTC brackets plus I and Y rod knuckles bolt straight to the standard face. Position sensing requires the optional -S magnet code: with it, CMSE or DMSE reed or solid-state switches seat in the body slots. This unit has no S code, so no magnet is fitted and no switch will read; order ACEJ80X160-30S instead if sensing is needed.
