The AirTAC Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-40S is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø63mm bore and 80mm 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.
The ACEJ63X80-40S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. A 63 mm bore delivers 1558.6 N push and 1458.1 N pull at 0.5 MPa, rising to 2182.1 N at 0.7 MPa, with a theoretical peak of 317.9 kgf at 1.0 MPa. The -40 code gives a 40 mm adjustment window: an external stop screw trims the 80 mm stroke down on site, so the usable extend range is 40-80 mm without changing the cylinder.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight jigs and gantries. Because this model carries the -S magnet, CMSE or DMSE reed and solid-state switches can be mounted directly in the body slots. As a rule of thumb, plan for roughly 935 N (about 95 kg) of real work at 0.5 MPa, and expect it to lift about 79 kg vertically with a 2:1 margin. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with fixed TPU bumpers at both ends.

| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

ACE-family variants: ACE (double acting), ASE / ATE (single acting push / pull), ACED (double rod), ACEJ (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 1558.6 N push at 0.5 MPa clamps steel brackets in automotive weld jigs, and the 40-80 mm adjustable range absorbs fixture changes without swapping cylinders.
On carton palletizing lines the 63 mm bore presses stacked layers square, lifting about 79 kg vertically with a 2:1 margin, while CMSE switches confirm top of stroke.
The short ISO 21287 body fits under guarding where a full-length profile cylinder will not, diverting packages between conveyor lanes at 30-500 mm/s.
Size up or down by force: the 50 mm bore gives 981.7 N push at 0.5 MPa, while the 80 mm bore reaches 2513.3 N, so the 63 mm sits in the mid-heavy class. If the stroke may still change after commissioning, the 40 mm trim window covers it; if the load must stay put on air loss, add an external locking valve, since the stop screw is an end stop only and the piston will drift when pressure drops. FA flange or LB foot mountings bolt to the ISO 21287 face, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke sensing.
Quick checklist
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa it pushes 2182.1 N; theoretical maximum is 317.9 kgf at 1.0 MPa. The -40 code is a 40 mm adjustment window: an external stop screw shortens the 80 mm extend stroke to any setting from 40 to 80 mm. It is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches mount in the body slots. FA flange and LB foot mountings plus I and Y rod knuckles bolt straight to the standard face; the rod end is female M10x1.5 and the port is 1/8" PT.
