About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-30SB
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ63X90-30SB pairs a 63 mm bore with a 90 mm stroke and a male-threaded 16 mm rod. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa, with a theoretical ceiling of 317.9 kgf at 1.0 MPa. The external stop screw trims the extend stroke anywhere inside the ordered 30 mm window, giving a usable 60-90 mm range without changing the valve or re-plumbing.
The hard-anodized aluminium body with an S45C hard-chrome rod keeps the envelope tight: the short build saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses and gantries where a full-length body will not fit. As a rule of thumb, plan on roughly 935 N of real work at 0.5 MPa, which is about 95 kg lifted vertically with margin. The fitted -S magnet lets CMSE / DMSE switches report end positions, and the fixed TPU bumpers at both ends absorb end-of-stroke shock.

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 ACEJ63X90-30SB Is Used
Fixture clamping on CNC pallets
The 1558.6 N push at 0.5 MPa clamps aluminium or steel workpieces in machining fixtures, and the 60-90 mm adjustable range lets one cylinder serve different pallet heights.
Lift-and-lower gantry stations
With about 95 kg of vertical lift capacity at a 2:1 margin, it raises and lowers small pallets or nest trays inside the short envelope of a transfer gantry.
Case ejector on packing lines
The 90 mm stroke, trimmed down via the stop screw, ejects cartons or trays from a conveyor lane at speeds up to 500 mm/s, with CMSE switches confirming each eject.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-30SB the Right Cylinder?
At 1558.6 N push at 0.5 MPa this 63 mm bore suits clamping and lifting in the 90-150 kg class; step down to the 50 mm bore (981.7 N) for lighter tooling or up to the 80 mm bore (2513.3 N) for heavier fixtures. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the piston still drifts if air is lost. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted magnet accepts CMSE / DMSE switches. Operating pressure is 0.15-1.0 MPa (22-145 psi) with speed from 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 ACEJ63X90-30SB 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 -30 code is a 30 mm adjustment window: an external stop screw shortens the 90 mm extend stroke by up to 30 mm, so the usable range is 60-90 mm. It shortens the stroke only and acts as a mechanical end stop, not a load-holding brake.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots. FA flange and LB foot mounts fit the standard ISO 21287 face, ports are 1/8" PT, and the rod end is male threaded (B code).
