The AirTAC Airtac ACE Compact Cylinder ACE125X10 is a genuine double acting ISO 21287 compact air cylinder with a Ø125mm bore and 10mm stroke, 1/4" 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 AirTAC ACE125X10 is a double acting compact cylinder built to ISO 21287, with a 125 mm bore and a 10 mm stroke. It delivers a 6135.9 N push force at 0.5 MPa, which is about 625 kgf of theoretical thrust, so it suits heavy clamping and pressing tasks in a very short envelope. The fixed TPU bumper at each end absorbs impact energy, while the hard-anodized aluminium body and S45C hard-chrome rod resist wear in continuous service.
Because the body is about 50% shorter than an ISO 15552 profile cylinder of the same bore, this unit fits into tight machine frames and guarding where a full-length cylinder will not. For a real workload, plan on roughly 0.6 times the rated push, which gives about 375 kgf of usable force at 0.5 MPa, so you can safely lift or press parts up to that weight with a 2:1 margin. The 1/4" port and M16x2.0 female rod thread match standard ISO 21287 accessories, and the optional -S magnet code enables CMSE or DMSE sensors for position detection.

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.
Use in a CNC machining center to clamp large steel workpieces with 6135.9 N of push force at 0.5 MPa, holding parts securely during milling operations. The short body fits under a low machine guard while the fixed TPU bumper prevents shock damage at the end of each clamp stroke.
In a small hydraulic press retrofit, this cylinder provides a 10 mm stroke to press bearings or bushings into housings with up to 8590.3 N at 0.7 MPa. The compact ISO 21287 body saves space on the press frame, and the hard-chrome rod resists scoring from repetitive contact.
Mount on a stamping die to eject formed metal parts after each cycle, using the 5890.5 N pull force at 0.5 MPa to retract the rod quickly. The 10 mm stroke is enough to clear the part, and the fixed TPU bumper at both ends handles the high cycle rates without needing adjustment.
When sizing for a 125 mm bore, compare this ACE125X10 against the ACE100X10, which pushes 3927.0 N at 0.5 MPa, to confirm you need the extra 2208.9 N of force. If your application requires less thrust, stepping down to a 100 mm bore saves space and air consumption, while the 125 mm bore provides the highest force in the ACE range. For a 10 mm stroke, this cylinder is ideal for short travel operations like clamping, pressing, or ejecting, but remember it is double acting only and will not hold a load if air pressure is lost. Choose the optional -S magnet if you need position feedback, and select from FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC mounting brackets to match your fixture.
Quick checklist
At 0.5 MPa, the push force is 6135.9 N and the pull force is 5890.5 N. At 0.7 MPa, push increases to 8590.3 N and pull to 8246.7 N. The theoretical maximum force at 1.0 MPa is 1251.4 kgf. These values assume standard air pressure and a clean, lubricated system.
Yes, it is an ISO 21287 compact cylinder with a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder of the same bore. This allows it to fit into tight machine frames and guarding. It has a fixed TPU bumper at both ends for shock absorption, and the optional -S magnet enables CMSE or DMSE sensors for position feedback.
