Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-10B
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-10B 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 ACEJ20X60-10B
The ACEJ20X60-10B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 60 mm stroke by up to 10 mm, giving a usable range of 50-60 mm without changing the order code. At 0.5 MPa the 20 mm bore pushes 157.1 N and pulls 117.8 N, rising to 219.9 N on the extend stroke at 0.7 MPa, with a theoretical ceiling of 32 kgf at 1.0 MPa. The male (B) rod thread on the 10 mm rod bolts straight to standard tooling.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. Fixed TPU bumpers at both ends absorb end-of-stroke shock, and the rod end stop is a mechanical trim only - on air loss the piston still drifts, so it never holds a load. Plan for about 94 N (roughly 9 kg) of real work at 0.5 MPa, which lifts 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 ACEJ20X60-10B Is Used
Jig clamping on CNC fixtures
The 50-60 mm adjustable window lets a machinist dial the clamp stroke to the fixture without shimming, and the male rod thread accepts standard knuckle accessories.
Small-part ejector on packaging lines
157.1 N of push at 0.5 MPa kicks cartons or blister trays off a conveyor, with 30-500 mm/s speed control via meter-out flow valves.
Sample press in lab automation
About 9 kg of usable working force at 0.5 MPa presses vials or microplates in compact analyzer frames too short for a full-length profile cylinder.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ20X60-10B the Right Cylinder?
For this stroke band, the 16 mm bore (100.5 N push at 0.5 MPa) suits lighter pick-and-place, while stepping up to the 25 mm bore (245.4 N push) doubles the margin for heavier clamping. Both share the M5x0.8 port of the 20 mm bore. If the load must stay put when air drops, add an external brake rather than relying on the stop screw. Mount with FA flange or LB foot, and order the optional -S magnet if CMSE / DMSE switch sensing is needed - without -S there is no magnet fitted.
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 ACEJ20X60-10B FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa push is 219.9 N and pull 164.9 N; theoretical maximum is 32 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, fluid air filtered to 40 um. The port is M5x0.8, the rod is 10 mm with a male thread, and the -10 code gives a 10 mm extend-stroke adjustment window (usable 50-60 mm).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends and FA flange or LB foot mounting on the standard face. Sensing requires the optional -S magnet ordered with the cylinder; this model (no S code) has no magnet, so CMSE / DMSE switches cannot be mounted on it.
