About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X40-30B
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ63X40-30B pairs a 63 mm bore with a 40 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 maximum 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 range of 10-40 mm without changing hardware.
The hard-anodized aluminium body with an S45C hard-chrome rod saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into dense machine frames. Sized for real work, plan on about 935 N of usable push at 0.5 MPa, which is roughly 79 kg of vertical lifting with a 2:1 margin. Air ports are 1/8", speed runs 30-500 mm/s, and a fixed TPU bumper sits at each end.

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 ACEJ63X40-30B Is Used
Press-fit bushing insertion
The 1558.6 N push at 0.5 MPa seats bronze bushings into aluminium housings on a small assembly cell, with the 30 mm window letting one cylinder serve several housing depths.
Fixture clamping on machining centers
Clamps cast-iron brackets against hard stops in a 4th-axis fixture, where the short ISO 21287 body fits under the fixture plate and the stop screw sets exact clamp height per part.
Pallet gate actuation
Swings or lifts heavy pallet-stop gates on a warehouse conveyor line, lifting about 79 kg vertically with a 2:1 margin at 0.5 MPa.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X40-30B the Right Cylinder?
At 63 mm bore this sits in the mid-heavy class: step down to a 50 mm bore for 981.7 N push at 0.5 MPa, or up to 80 mm for 2513.3 N when the clamp load grows. The stop screw is a mechanical end stop only, so on air loss the piston drifts and it should not be relied on to hold a load mid-stroke. FA flange or LB foot mounts and I/Y rod knuckles bolt to the ISO 21287 face. This unit has no magnet; if CMSE or DMSE switches are needed, order the -S version.
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 ACEJ63X40-30B FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa, 2182.1 N push and 2041.3 N pull; theoretical maximum 317.9 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: an external stop screw shortens the 40 mm extend stroke by up to 30 mm, so the working range is 10-40 mm. It is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost.
The ISO 21287 body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the face. Position sensing needs the optional -S magnet code; this model has no magnet, so CMSE or DMSE switches cannot be used unless -S is ordered.
