About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X40-10SB
The ACEJ63X40-10SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 63 mm bore delivers 1558.6 N pushing and 1458.1 N pulling at 0.5 MPa, rising to 2182.1 N at 0.7 MPa, with a theoretical peak of 317.9 kgf at 1.0 MPa. An external stop screw trims the 40 mm stroke by up to 10 mm, giving a usable extend range of 30-40 mm, and the -S code means the magnet is already fitted so CMSE or DMSE switches can be mounted anywhere along the body slots.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping fixtures and machine frames. In practice, plan on roughly 935 N of real work at 0.5 MPa (about 0.6 of the push force), which corresponds to lifting around 95 kg vertically - or about 47 kg with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the hard-anodized aluminium body with an S45C hard-chrome plated 16 mm rod stands up to continuous production duty.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X40-10SB Is Used
Clamping of machined housings
The 1558.6 N push at 0.5 MPa clamps aluminium gearbox housings in a CNC fixture, with the 30-40 mm adjustable window tuned to each part's clamp height.
Short-stroke press station
A compact benchtop press for pressing bushings into pump brackets uses the 63 mm bore's force class where a full-length profile cylinder will not fit under the frame.
Pallet-stacker gate actuator
Swinging a safety gate on a warehouse pallet stacker, with the fitted -S magnet feeding a CMSE switch to confirm the gate is fully closed before travel.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X40-10SB the Right Cylinder?
At 63 mm bore this sits in the mid-heavy force class: a 50 mm bore gives 981.7 N push at 0.5 MPa and an 80 mm bore gives 2513.3 N, so pick the 63 mm when your clamping or pressing load falls between those two. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston will still drift, so do not rely on it to hold a load.
The male rod thread (B code) suits directly threaded tooling, while FA flange, LB foot and FTC brackets plus I and Y rod knuckles bolt to the standard ISO 21287 face. The fitted -S magnet lets you add CMSE / DMSE switches for end-of-stroke or position signals. Ports are 1/8" on this bore, pressure runs 0.15-1.0 MPa (22-145 psi) and 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 ACEJ63X40-10SB FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa it pushes 2182.1 N and pulls 2041.3 N; the theoretical maximum is 317.9 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 40 mm extend stroke by up to 10 mm, so the usable range is 30-40 mm. It runs double acting on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, at 30-500 mm/s, with a 1/8" port and a 16 mm male-threaded rod.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and fixed TPU bumpers at both ends absorb end-of-stroke shock. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be clipped into the body slots for position signals. FA flange, LB foot and FTC brackets plus I and Y rod knuckles mount directly on the ISO 21287 face; PT ports are standard and a G port thread is available on request.
