About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-20SB
The ACEJ63X60-20SB 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 20 mm, giving a usable range of 40-60 mm without changing the order code. At 0.5 MPa the 63 mm bore pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa. The male rod thread (B code) and the fitted -S magnet make it ready for CMSE / DMSE switch mounting straight out of the box.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight press fixtures and guarding where a full-length body will not reach. In practice, plan for roughly 935 N of real work at 0.5 MPa (about 0.6 of the push figure), which corresponds to lifting about 79 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the hard-anodized aluminium body with an S45C hard-chrome plated rod stands up to daily cycling.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-20SB Is Used
Press-fit clamping in assembly fixtures
With 1558.6 N push at 0.5 MPa and a 40-60 mm trim range, the cylinder clamps bearing housings or bushings into housings on an automotive sub-assembly line, with the stop screw set once per fixture change.
Lifting stamped brackets off a die
The bore lifts about 79 kg vertically with a 2:1 margin, so it can raise small steel stampings clear of a press die; the fitted -S magnet drives a DMSE switch to confirm full retraction before the next stroke.
Indexing stops on a conveyor line
The 60 mm stroke, trimmed down to 40 mm on site, extends a stop pin into the path of cartons on a packaging conveyor; the short body fits inside the side guarding where a longer profile cylinder cannot.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-20SB the Right Cylinder?
Size both ways before committing: the 50 mm bore delivers 981.7 N push at 0.5 MPa, while the 80 mm bore reaches 2513.3 N, so the 63 mm bore at 1558.6 N sits squarely between them for mid-load clamping and lifting. Remember the stop screw is a mechanical end stop for the extend stroke only - it does not lock the piston mid-stroke, and the rod will drift if air is lost. FA flange or LB foot mounts bolt to the ISO 21287 face, and the -S magnet in this model lets CMSE / DMSE switches report end positions. Air supply: 0.15-1.0 MPa (22-145 psi), filtered to 40 um, speed 30-500 mm/s.
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 ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-20SB FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push is 2182.1 N and pull 2041.3 N; theoretical maximum is 317.9 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 60 mm extend stroke by up to 20 mm, so the working range is 40-60 mm. It is double acting, runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, and cycles at 30-500 mm/s.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends to absorb end-of-stroke energy. This unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clamped into the body slots to signal end positions. FA flange and LB foot mounts plus I and Y rod knuckles bolt to the standard ISO 21287 face, and the B code gives a male rod thread.
