The AirTAC Airtac ACE Compact Cylinder ACE50X40SB is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 40mm 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 AirTAC ACE50X40SB is a double acting compact cylinder that extends and retracts its rod with air pressure, delivering a 981.7 N push force at 0.5 MPa. Its ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames where a full-length unit will not.
The hard-anodized aluminium body and hard-chrome plated S45C steel rod resist wear in continuous cycling. The fixed TPU bumper at each end absorbs impact, and the optional -S magnet is fitted here, enabling CMSE or DMSE reed and solid-state switches for position sensing. For a real workload, plan around 589 N at 0.5 MPa, which is about 60 kg of vertical lift with a 2:1 safety margin.

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 | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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.
Clamp small parts in a CNC vise or fixture with 981.7 N of push force at 0.5 MPa, enough to hold aluminum or plastic workpieces securely during milling.
Actuate a stop finger on a packaging conveyor to divert boxes. The 40 mm stroke retracts quickly, and the compact body fits between roller sections.
Push a safety interlock pin into a machine guard frame. The 50 mm bore provides reliable force, and the optional magnet lets a sensor confirm the guard is closed.
Choose this 50 mm bore when you need a mid-range force: it pushes 981.7 N at 0.5 MPa, compared to 402.1 N for a 32 mm bore or 1558.6 N for a 63 mm bore. The 40 mm stroke suits short indexing moves, and the male rod thread (B) lets you bolt on a clevis or rod end directly.
Since this model carries the -S magnet, you can attach CMSE or DMSE switches to confirm position. Mount it with FA/FB flange, LB foot, CA/CB clevis, or SDB pivot brackets. Remember, this cylinder does not hold its load when air is removed - use a rod lock or pilot check valve for vertical holding.
Quick checklist
At 0.5 MPa, push is 981.7 N and pull is 881.2 N. At 0.7 MPa, push is 1374.4 N and pull is 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa (22-145 psi).
The ACE50X40SB body is about 50% shorter than an ISO 15552 profile cylinder of the same bore, so it fits in confined jigs and gantries. It has a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows CMSE or DMSE switch mounting for position feedback.
