About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-50B
The ACEJ63X70-50B 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. The B code gives a male 16 mm rod thread, and the 1/8" port matches this bore class.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight presses and fixtures. As a working rule, plan on roughly 935 N of real work at 0.5 MPa, which lifts about 95 kg vertically - or about 48 kg with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke impact, and the external stop screw trims the 70 mm stroke by up to 50 mm, giving a usable range of 20-70 mm.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-50B Is Used
Bench-top press station
The 1558.6 N push at 0.5 MPa suits crimping and staking small aluminium housings, while the 20-70 mm adjustable range lets one cylinder serve several part heights.
Weld fixture clamping
Short ISO 21287 body fits inside tight weld jigs where a full-length profile cylinder would foul the tooling, with FA flange mounting for fast fixture swaps.
Pallet gate actuator
With about 95 kg vertical-lift equivalent at 0.5 MPa, the cylinder swings heavy conveyor gates and stops on packaging lines at 30-500 mm/s.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-50B the Right Cylinder?
At this force class the 63 mm bore covers mid-duty clamping and pressing; step down to a 50 mm bore (981.7 N push at 0.5 MPa) for lighter work, or up to an 80 mm bore (2513.3 N) when the load grows. Remember the stop screw is a mechanical end stop only - on air loss the piston drifts, so it is not a load-holding lock. FA flange or LB foot mounting bolts to the ISO 21287 face, and if position feedback is needed later, order the -S variant so CMSE / DMSE switches can be fitted; this model has no magnet.
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 ACEJ63X70-50B 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; theoretical maximum is 317.9 kgf at 1.0 MPa. The -50 code sets a 50 mm adjustment window: an external stop screw shortens the 70 mm extend stroke by up to 50 mm, so the working range is 20-70 mm. It shortens the stroke only and never extends it past 70 mm.
It is an ISO 21287 compact cylinder, roughly 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. Operating range is 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, -20 to +70 C. This model has no magnet; order the -S code to enable CMSE / DMSE switches. Mounting options include FA flange and LB foot, and the B code provides a male rod thread.
