The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-30B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 275mm 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.
This 80 mm bore ACEJ is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 275 mm stroke by up to 30 mm on site, giving a usable range of 245-275 mm without swapping the cylinder. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, and the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, gantries and guard spaces a full-length body cannot reach.
The hard-anodized aluminium body carries a S45C hard-chrome plated 20 mm rod, fixed TPU bumpers absorb end-of-stroke energy at both ends, and the male rod thread (B code) bolts straight into standard fixtures. Operating window is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.

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.

|---|---|
| 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. |
| ×275 | 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.
The 275 mm stroke and about 128 kg vertical-lift margin suit gate lift and pallet-stop arms on warehouse conveyor lines, where the compact body mounts inside guard framing too tight for a long-profile cylinder.
On CNC fixture plates the FA flange or LB foot bolts to the ISO 21287 face, and the male rod thread (B code) takes I or Y knuckles for clamping turbine housings and gearbox casings in machining centres.
The 275 mm stroke sits inside the 300 mm maximum standard stroke for this bore, so no made-to-order build is needed. The stop screw is a mechanical end stop only: it sets the extend position but does not lock the piston, so on air loss the rod still drifts. If position feedback is needed later, order the -S variant, since this unit has no magnet and accepts no CMSE / DMSE switches.
Quick checklist
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa it pushes 3518.6 N and pulls 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -30 code gives a 30 mm adjustment window: the external stop screw shortens the 275 mm extend stroke to any length from 245 to 275 mm. It runs on 0.15-1.0 MPa (22-145 psi) filtered air at 30-500 mm/s, with fixed TPU bumpers at both ends.
It is an ISO 21287 compact cylinder: a hard-anodized aluminium body with a roller-burnished bore, threaded aluminium covers, a S45C hard-chrome plated 20 mm rod, and a body about 50% shorter in mounting length than an ISO 15552 profile cylinder. This unit has no magnet, so no switch can be read; if you need CMSE or DMSE reed or solid-state switches, order the -S version with the optional magnet. Mounting options include FA flange, LB foot and FTC brackets.
