About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-10SB
A double acting ISO 21287 compact cylinder, the ACEJ63X50-10SB pairs a 63 mm bore with a 50 mm stroke that a stop screw trims on site: the -10 window lets you shorten the extend stroke anywhere in a 40-50 mm range. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa. The male rod thread (B code) bolts straight into tooling, and the -S magnet this model carries lets CMSE / DMSE switches report end positions.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight weld fixtures and palletizer heads where a full-length body will not fit. A hard-anodized aluminium body runs against an S45C hard-chrome-plated 16 mm rod, with fixed TPU bumpers at both ends. Plan real work at roughly 935 N (about 0.6 of the push force), which corresponds to lifting about 79 kg vertically with a 2:1 margin.

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 ACEJ63X50-10SB Is Used
Weld fixture clamping
The 40-50 mm trimmed stroke clamps car-body brackets with 1558.6 N of push, and the male rod thread takes a formed clamp arm directly.
Palletizer push-off
Pushing cartons off a forming station at 30-500 mm/s, the compact body fits the short head space beside the conveyor frame.
Gate positioning with feedback
The fitted -S magnet drives CMSE / DMSE switches at both ends of the trimmed stroke, confirming gate-open and gate-close on a packaging line.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-10SB the Right Cylinder?
At 1558.6 N push at 0.5 MPa, the 63 mm bore sits between the 50 mm bore (981.7 N) and the 80 mm bore (2513.3 N) - step down for lighter clamping, up if your fixture needs over 2 kN. If the load must stay put on air loss, add an external locking valve, because the stop screw sets stroke length only and never holds position. FA flange or LB foot mount on the ISO 21287 face, and this unit already includes the optional -S magnet plus a male rod thread for direct tooling attachment.
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 ACEJ63X50-10SB FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa those rise to 2182.1 N and 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -10 code sets a 10 mm adjustment window: an external stop screw shortens the 50 mm extend stroke, giving a usable range of 40-50 mm. It is a mechanical end stop only - on air loss the piston still drifts, so use a separate lock for load holding.
It is an ISO 21287 compact cylinder whose body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, an S45C hard-chrome 16 mm rod and fixed TPU bumpers at both ends. FA flange and LB foot mounts bolt to the standard face. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted; air supply is 0.15-1.0 MPa (22-145 psi) filtered to 40 um.
