Airtac TACE Guided Compact Cylinder TACE20X70
The AirTAC Airtac TACE Guided Compact Cylinder TACE20X70 is a genuine double acting, non-rotating ISO 21287 compact air cylinder with a Ø20mm bore and 70mm 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 TACE20X70
Built for tight cells, the AirTAC TACE20X70 is a double acting, non-rotating compact cylinder with a 20 mm bore and a 70 mm stroke. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, so plan for about 94 N of real work at that pressure rather than the full rating. Twin guide rods on a yoke stop the tooling rotating and carry side load, keeping a gripper or plate square without an external guide. The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it drops into jigs, guards and gantries where a full-length body will not.
The hard-anodized aluminium body carries an S45C piston rod with hard-chrome plating, and threaded aluminium-alloy covers make service straightforward. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the rod runs 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air. Vertically, the 157.1 N push equates to about 16 kgf, so with a 2:1 margin it lifts about 8 kg. This version has no magnet fitted; order the optional -S code to enable CMSE / DMSE switches. The port is M5x0.8 and the rod ends in a female M6x1.0 thread.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 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 TACE20X70 Is Used
Connector ejection in PCB assembly fixtures
Pushing finished connectors off a machined nest on an electronics assembly line: the 70 mm stroke clears the nest in one move, and the twin-guide yoke keeps the pusher square to the part without extra rails.
Blister-pack side sorting on pharma lines
Side-pushing rows of blister packs from a conveyor lane into a reject or transfer chute: 157.1 N of push at 0.5 MPa moves the packs at 30-500 mm/s, and the short body fits the tight guard space beside the lane.
Lid clamping under a lab filling hood
Clamping microplate lids during automated filling: the usable force of about 94 N at 0.5 MPa holds the lid steady, and the compact ISO 21287 body fits under the hood where a full-length cylinder cannot.
Is the Airtac TACE Guided Compact Cylinder TACE20X70 the Right Cylinder?
If 157.1 N of push at 0.5 MPa is marginal for your load, step up to the 25 mm bore (245.4 N push) or down to the 16 mm bore (100.5 N push) - both stay within the same ISO 21287 compact series. The piston drifts if air is lost, so for a held load add a rod lock or pilot check valve rather than relying on the cylinder itself. The 70 mm stroke sits inside the 100 mm maximum standard stroke for this bore, so it ships as a standard part. Mount with an FB flange, CA/CB clevis, CR or FTC, and order the optional -S magnet if CMSE / DMSE sensing is planned later.
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 TACE20X70 FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N. At 0.7 MPa the figures rise to 219.9 N push and 164.9 N pull. The theoretical maximum is 32 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed runs 30-500 mm/s, and the rod is 10 mm with a female M6x1.0 thread.
The ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends and mounting choices of FB flange, CA/CB clevis, CR or FTC. No magnet is fitted on this model; order the optional -S code and CMSE / DMSE switches can then be mounted in the slots around the body.
