Airtac TACE Guided Compact Cylinder TACE25X20S
The AirTAC Airtac TACE Guided Compact Cylinder TACE25X20S is a genuine double acting, non-rotating ISO 21287 compact air cylinder with a Ø25mm bore and 20mm stroke, M5×0.8 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. Twin guide rods keep the tooling from rotating.

About the Airtac TACE Guided Compact Cylinder TACE25X20S
Double acting and non-rotating, the TACE25X20S drives a 25 mm bore through a 20 mm stroke with 245.4 N of push and 206.2 N of pull at 0.5 MPa, rising to 343.6 N / 288.6 N at 0.7 MPa and a theoretical 50.1 kgf at 1.0 MPa. Twin guide rods on a yoke stop the tooling rotating and carry side load, so a gripper or clamp plate stays square without any external guide. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and pick-and-place heads where a full-length cylinder will not fit.
A hard-anodized aluminium body with a roller-burnished bore runs against an S45C hard-chrome-plated 10 mm rod, and a fixed TPU bumper at each end absorbs end-of-stroke energy. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted in the body slots for end-of-stroke signalling. For sizing, plan on about 147 N of usable force at 0.5 MPa rather than the full rating, and expect roughly 25 kg of vertical lift capability - halve that to about 12 kg for a 2:1 margin on a lifting fixture. Air supply is 0.15-1.0 MPa (22-145 psi) filtered to 40 um, speed 30-500 mm/s, temperature -20 to +70 C.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating; guide rods: stainless steel (Ø12-40) / S45C (larger). 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.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin. Twin guide rods stop the tooling rotating.

Where the Airtac TACE Guided Compact Cylinder TACE25X20S Is Used
Electronics press ejector
The 245.4 N push at 0.5 MPa is enough to eject small PCB connectors from a test nest, while the 20 mm stroke keeps the head inside a compact fixture frame.
Bottling line reject gate
A short 20 mm kick is all a reject finger needs to push an off-spec bottle off a 60 mm conveyor lane, and the twin-guide yoke keeps the finger from twisting under side contact.
Lab sample clamp
Clamping sample trays in an automated analytical instrument: the non-rotating 10 mm rod holds the clamp pad square, and the -S magnet feeds a CMSE switch to confirm the clamp is closed before the cycle starts.
Is the Airtac TACE Guided Compact Cylinder TACE25X20S the Right Cylinder?
At 245.4 N push at 0.5 MPa this 25 mm bore sits between the 20 mm bore (157.1 N) and the 32 mm bore (402.1 N) - step down when the load is under 90 N, step up above 240 N. Remember the piston drifts when air is lost, so for a held load add a rod lock or pilot check valve rather than relying on the cylinder itself. Mounting choices are FB flange, CA/CB clevis, CR and FTC, and because this variant is ordered with the -S magnet, CMSE / DMSE switches are ready to fit out of the box.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac TACE Guided Compact Cylinder TACE25X20S FAQ
At 0.5 MPa it pushes 245.4 N and pulls 206.2 N; at 0.7 MPa that rises to 343.6 N push and 288.6 N pull. The theoretical maximum is 50.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s. For real work, budget about 147 N at 0.5 MPa, which corresponds to roughly 25 kg of vertical lift - use about 12 kg if you want a 2:1 safety margin.
It is an ISO 21287 compact cylinder: a hard-anodized aluminium body with threaded aluminium covers, an S45C hard-chrome-plated 10 mm rod with an M6x1.0 female thread, an M5x0.8 air port, and a fixed TPU bumper at each end that decelerates the piston at stroke ends. The body saves about 50% of the mounting length of an ISO 15552 profile cylinder. Mounting options are FB flange, CA/CB clevis, CR and FTC. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be snapped into the body slots for position signalling.
