About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-40S
The ACEJ63X60-40S 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 40 mm on site, giving a usable range of 20-60 mm without changing the cylinder. At the 63 mm bore it delivers 1558.6 N push and 1458.1 N pull at 0.5 MPa, rising to 2182.1 N push at 0.7 MPa. A fixed TPU bumper at each end absorbs end-of-stroke impact, and the hard-anodized aluminium body with an S45C hard-chrome plated 16 mm rod stands up to continuous jig duty.
Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this model slots into clamping fixtures and gantries where a full-length cylinder will not reach. In practice, plan for roughly 935 N of real work at 0.5 MPa (about 0.6 of the push rating), which is around 95 kg of vertical lift - halve that to about 47 kg if you want a 2:1 margin on a lifting application. The fitted -S magnet lets CMSE / DMSE reed or solid-state switches report end positions, and FA flange or LB foot mounts bolt straight to the ISO 21287 face.

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 ACEJ63X60-40S Is Used
Press-fit bushing insertion
The 1558.6 N push at 0.5 MPa seats automotive bushings into control-arm housings, with the 40 mm window letting the line set the stop anywhere from 20 to 60 mm per variant.
Pallet-gate lift on packaging lines
With about 95 kg of vertical lift equivalent at 0.5 MPa, the cylinder raises gate and guard panels on carton palletizers, and the compact body fits inside the guard frame.
Position-verified weld fixture clamp
The fitted magnet drives CMSE / DMSE switches that confirm full clamp closure on robotic weld fixtures before the weld sequence is allowed to start.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-40S the Right Cylinder?
Size against the load: the next bore down, ACEJ50, gives 981.7 N push at 0.5 MPa, while the 80 mm bore steps up to 2513.3 N. If your clamping or pressing load sits near 900-950 N, this 63 mm bore keeps a sensible reserve. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve where a load must stay put. Choose the female M10x1.5 rod thread shown here or the -B male variant, and order CMSE / DMSE switches alongside since the magnet is carried only on -S models like this one.
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 ACEJ63X60-40S 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 -40 code is the adjustment window: an external stop screw shortens the 60 mm extend stroke by up to 40 mm, so the working range is 20-60 mm. It is a mechanical end stop only - it does not hold a load if air is lost. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the air must be filtered to 40 um.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it suits tight jigs and gantries. FA flange and LB foot mounts bolt to the standard face, with I and Y rod knuckles available. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots for end-position sensing. The rod end is female M10x1.5, the port is 1/8" PT, and a fixed TPU bumper at both ends absorbs end-of-stroke energy.
