The AirTAC Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-10SB is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø63mm bore and 75mm 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 ACEJ63X75-10SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 75 mm stroke by up to 10 mm, giving a usable range of 65-75 mm without changing hardware. At 0.5 MPa the 63 mm bore delivers 1558.6 N on extend and 1458.1 N on retract, rising to 2182.1 N and 2041.3 N at 0.7 MPa, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The male rod thread (B code) and PT ports suit direct tooling attachment.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, clamping fixtures and machine frames where a full-length cylinder will not reach. In practice, plan for roughly 935 N of real work at 0.5 MPa, which lifts about 79 kg vertically with a 2:1 margin. The S code means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots for end-of-stroke signalling.

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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 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 extend force at 0.5 MPa swages, stakes or presses bushings into aluminium housings, and the 10 mm window lets you dial the 75 mm stroke down to 65 mm to match part height.
Mounted by FA flange on a machining-centre jig, the male rod thread takes a knuckle to clamp castings with about 935 N of usable force, while the fitted magnet feeds a CMSE switch to the PLC.
In an EV assembly cell, the compact body fits inside a guarding frame and lifts about 79 kg vertically with a 2:1 margin, pressing lids home at 30-500 mm/s.
Size against neighbours: the 50 mm bore gives 981.7 N push at 0.5 MPa, while stepping up to the 80 mm bore raises it to 2513.3 N, so pick 63 mm when your fixture needs roughly 1.5 kN of extend force. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston still drifts, so add a separate valve or lock for load holding. FA flange, LB foot and FTC brackets plus I and Y rod knuckles bolt to the ISO 21287 face; PT ports are standard and G threads can be ordered.
Quick checklist
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa those rise to 2182.1 N and 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. It is double acting with a 10 mm adjustable window on the 75 mm stroke (65-75 mm usable), runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, with a fixed TPU bumper at both ends and a 1/8" PT port.
An external stop screw shortens the extend stroke on site by up to 10 mm, so the 75 mm stroke can be trimmed to 65 mm; it is a mechanical end stop, not a mid-stroke lock. Because this model carries the optional -S magnet, CMSE / DMSE reed or solid-state switches mount in the body slots for end-of-stroke detection. The hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, and FA, LB and FTC mountings bolt straight to the ISO 21287 face.
