About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-50B
A double acting ISO 21287 compact cylinder, the ACEJ63X75-50B pairs a 63 mm bore with a 75 mm stroke that an external stop screw trims on site by up to 50 mm, giving a usable extend range of 25-75 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa. The male rod thread (B code) on the 16 mm S45C hard-chrome rod bolts straight to standard tooling plates.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses and fixtures where a full-length body will not fit. A fixed TPU bumper at each end absorbs end-of-stroke shock, and with 1558.6 N of push you can plan on roughly 95 kg of vertical lift with a 2:1 margin (1558.6 / 9.81 halved). Operating window is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.

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 ACEJ63X75-50B Is Used
Pneumatic press station
The 2182.1 N push at 0.7 MPa stakes and swages aluminium terminals, while the 50 mm window lets technicians shorten the 75 mm stroke to match each die set.
Fixture clamping on a CNC line
Clamps machined housings against hard stops; the compact body fits inside the guard envelope where an ISO 15552 profile cylinder would be too long.
Pallet gate actuator
Swings or lifts a 90 kg pallet stop gate vertically with margin, using the male-threaded 16 mm rod and an LB foot mounting.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-50B the Right Cylinder?
At 0.5 MPa this 63 mm bore delivers 1558.6 N push; step down to the 50 mm bore (981.7 N) for lighter clamping or up to the 80 mm bore (2513.3 N) when the load grows. The -50 window suits jobs where the final stroke is tuned during commissioning, such as topping stops set after tooling changes. Note the stop screw is a mechanical end stop only: on air loss the piston drifts, so it is not a mid-stroke lock. FA flange, LB foot and I/Y rod knuckles mount on the ISO 21287 face; add the optional -S code if you later need CMSE / DMSE switch sensing, since this model ships without a 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 ACEJ63X75-50B 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 is 317.9 kgf at 1.0 MPa. The -50 code is a 50 mm adjustment window: an external stop screw shortens the 75 mm extend stroke by up to 50 mm, so the working range is 25-75 mm. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium barrel, threaded aluminium covers and fixed TPU bumpers at both ends. This model has no magnet fitted; order the optional -S version to enable CMSE / DMSE switches. FA flange, LB foot, FTC brackets and I/Y rod knuckles bolt to the standard face, and the B code gives a male rod thread on the 16 mm rod with a 1/8" PT port.
