Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-10SB
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-10SB is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø20mm bore and 60mm 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.

About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-10SB
The ACEJ20X60-10SB is a double acting ISO 21287 compact cylinder with a 20 mm bore and a 60 mm stroke that an external stop screw trims on site by up to 10 mm, giving a usable extend range of 50-60 mm. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, rising to 219.9 N push at 0.7 MPa. The male rod thread (B code) suits external rod accessories, and the fitted -S magnet lets CMSE / DMSE switches report position.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit. A hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers absorb end-of-stroke shock, and the two-way piston seal stores grease for long service. In practice, plan for roughly 94 N of real work at 0.5 MPa (about 60% of the push rating), which corresponds to lifting about 8 kg vertically with a 2:1 margin.

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.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-10SB Is Used
Fixture clamping on CNC pallets
The 94 N usable push at 0.5 MPa clamps small aluminium or plastic workpieces in drill jigs, while the 50-60 mm trim range matches shallow fixture pockets.
Small-part diverting on packaging lines
A 60 mm stroke with a 10 mm trim window nudges cartons or blisters off a conveyor, and the fitted magnet plus CMSE switch confirms each push is complete.
Sample press in lab automation
The compact body fits inside benchtop analysers where an ISO 15552 profile cylinder is too long, pressing vials or microplates with repeatable 157.1 N force.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-10SB the Right Cylinder?
At 157.1 N push (0.5 MPa), the 20 mm bore sits between the 16 mm bore (100.5 N) and the 25 mm bore (245.4 N). Choose the 16 mm bore when space and force demand are both minimal; step up to 25 mm if your load approaches 150 N or you want more reserve. Remember the stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod will drift if air is lost. Mount with FA flange or LB foot on the ISO 21287 face, add I or Y rod knuckles for side misalignment, and order CMSE / DMSE switches to pair with the fitted -S magnet.
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 ACEJ12 Adjustable Compact Cylinder ACEJ20X60-10SB FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa, 219.9 N push and 164.9 N pull; theoretical maximum is 32 kgf at 1.0 MPa. The -10 code sets a 10 mm adjustment window: an external stop screw shortens the 60 mm extend stroke by up to 10 mm, so the working range is 50-60 mm. It shortens only - it never extends past the ordered stroke and does not hold a load on air loss.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. FA flange and LB foot mounts bolt to the standard face, with I and Y rod knuckles for the male rod thread. The -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches can be clamped anywhere along the body slots. Speed range is 30-500 mm/s, pressure 0.15-1.0 MPa (22-145 psi), and fixed TPU bumpers absorb end-of-stroke energy.
