About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-10SB
A double acting ISO 21287 compact cylinder with a trimmable extend stroke: the external stop screw on this ACEJ63X70-10SB shortens the 70 mm stroke by up to 10 mm, giving a usable range of 60-70 mm without changing the cylinder. At 0.5 MPa the 63 mm bore delivers 1558.6 N on the extend stroke and 1458.1 N on retract, rising to 2182.1 N at 0.7 MPa. In practice, plan on roughly 935 N (about 95 kg of force) of real work at 0.5 MPa rather than the full rating.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping fixtures and machine frames. Because the -S magnet is fitted, CMSE or DMSE reed and solid-state switches mount directly in the body slots for end-of-travel detection. For vertical duty, the push force equates to lifting about 159 kg, or roughly 79 kg with a 2:1 margin. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi).

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-10SB Is Used
Press-fit bushing insertion
The 1558.6 N extend force at 0.5 MPa presses bronze bushings into pump housings, while the 10 mm window lets the setter trim the 70 mm stroke to seat depth on the bench.
Pallet gate actuation
Short-body packaging lines use the 63 mm bore to swing or lift pallet gates; the fitted magnet and a DMSE switch confirm gate-open position without extra brackets.
Weld fixture clamping
Automotive weld jigs take the compact 63 mm body where a full-length profile cylinder will not fit, with the male rod thread driving an adjustable clamp arm.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-10SB the Right Cylinder?
At 1558.6 N push at 0.5 MPa, bore 63 sits between bore 50 (981.7 N) and bore 80 (2513.3 N) - choose 63 when a 50 mm bore runs out of force but an 80 mm bore is oversized for the space. Note that the stop screw is a mechanical end stop only: on air loss the piston drifts, so it is not a load-holding device. The male rod thread (B code) and PT ports suit external rod couplings, and FA flange or LB foot mountings bolt to the ISO 21287 face.
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 ACEJ63X70-10SB 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, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 70 mm extend stroke by up to 10 mm, so the working range is 60-70 mm. The stop is a mechanical end stop, not a mid-stroke lock - on air loss the piston still drifts.
The ISO 21287 short 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 or DMSE reed and solid-state switches can be fitted in the body slots. Ports are 1/8" PT, rod thread is male, pressure is 0.15-1.0 MPa (22-145 psi), and speed is 30-500 mm/s.
