About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-50S
A double acting ISO 21287 compact cylinder with a 100 mm bore and a 300 mm stroke, the ACEJ100X300-50S pushes 3927 N and pulls 3769.9 N at 0.5 MPa, rising to 5497.8 N at 0.7 MPa. An external stop screw trims the extend stroke anywhere in the ordered 50 mm window, so the usable extend range is 250-300 mm. The hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod runs at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 300 mm stroke must fit inside a press frame or gantry. In practice, plan for roughly 2356 N (about 240 kg) of real work at 0.5 MPa, and expect it to lift about 200 kg vertically with a 2:1 margin. This model carries the optional -S magnet, so CMSE / DMSE switches can be mounted for end-of-stroke sensing, and a fixed TPU bumper absorbs end-of-stroke energy at both ends.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-50S Is Used
Heavy press-frame clamping
The 3927 N push at 0.5 MPa clamps steel weldments in automotive press fixtures, with the 50 mm window letting one cylinder serve several fixture heights between 250 and 300 mm.
Pallet-stacker lift assist
Lifting about 200 kg vertically with a 2:1 margin, the 100 mm bore suits pallet-lift and scissor-assist stations where a full-length ISO 15552 cylinder would not fit the mast.
Position-verified ejector
With the -S magnet fitted, CMSE or DMSE switches confirm full extend on a packaging-line ejector, while the stop screw dials the 300 mm throw down to match the carton pitch.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-50S the Right Cylinder?
At this force class, step down to a 63 mm bore (1558.6 N push at 0.5 MPa) for lighter clamping, or up to a 125 mm bore (6135.9 N) when the load needs more margin. The 300 mm stroke is the maximum standard stroke for the 100 mm bore, so no made-to-order length is needed. FA flange or LB foot mountings bolt to the ISO 21287 face, and the stop screw is a mechanical end stop only: on air loss the piston still drifts, so it is not a mid-stroke lock for holding a load.
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 ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-50S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa it pushes 5497.8 N and pulls 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -50 code is a 50 mm adjustment window: an external stop screw shortens the 300 mm extend stroke by up to 50 mm, giving a usable range of 250-300 mm. It shortens the stroke only and acts as a mechanical end stop, not a load-holding brake.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome 20 mm rod, 1/8" ports and a fixed TPU bumper at both ends. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be fitted for stroke-end detection. FA flange, LB foot and rod knuckles mount on the standard ISO 21287 face; operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
