About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-20SB
The ACEJ63X90-20SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: a stop screw on the outside of the 63 mm bore body trims the 90 mm stroke down by up to 20 mm, giving a usable range of 70-90 mm without swapping the cylinder. At 0.5 MPa it pushes with 1558.6 N and pulls with 1458.1 N, rising to 2182.1 N at 0.7 MPa, with a theoretical ceiling of 317.9 kgf at 1.0 MPa. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this force class fits into press fixtures and gantries that cannot house a full-length profile cylinder.
In practice, plan for roughly 935 N of real work at 0.5 MPa (about 60% of the push rating), which corresponds to lifting about 95 kg vertically - or halve that to roughly 79 kg if you want a 2:1 margin on a vertical lift. The male rod thread (B code) and the fitted -S magnet round out the package: CMSE or DMSE reed and solid-state switches can be clipped into the body slots for end-of-stroke signalling. The S45C hard-chrome plated rod runs in a hard-anodized aluminium body, with a fixed TPU bumper at each end absorbing end-of-stroke energy.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-20SB Is Used
Bench-top press fixture
A 95 kg-class pressing or staking operation on an electronics assembly bench: the 70-90 mm adjustable window lets the tooling set-up dial in the exact extend stroke, while the 2182.1 N push at 0.7 MPa handles the forming step.
Pallet strapper clamp arm
Clamping cartons on a warehouse strapping head: the short body tucks under the guard where a full-length ISO 15552 profile cylinder will not fit, and the fitted magnet plus a DMSE switch confirms the clamp is home before the strap cycle starts.
Machined-part ejector
Ejecting a housing from a CNC fixture: about 79 kg vertical lift capability at a 2:1 margin covers typical aluminium workpieces, and the male rod thread takes a Y knuckle to absorb slight fixture misalignment.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-20SB the Right Cylinder?
Size check: if 1558.6 N push at 0.5 MPa is more than your jig needs, the 50 mm bore delivers 981.7 N in the same compact envelope; if you need more, the 80 mm bore reaches 2513.3 N but needs a 1/4" port instead of this model's 1/8". Remember the stop screw only shortens the extend stroke within the ordered 20 mm window - it is a mechanical end stop, not a mid-stroke lock, so on air loss the piston can still drift and the load is not braked.
Mount FA flange or LB foot hardware straight to the ISO 21287 face, and add I or Y rod knuckles on the male thread for slight misalignment. The -S magnet is already fitted on this model, so position feedback with CMSE / DMSE switches works out of the box; running pressure is 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 ACEJ63X90-20SB 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 -20 code sets a 20 mm adjustment window: an external stop screw shortens the 90 mm extend stroke by up to 20 mm, so the working range is 70-90 mm. It cannot lengthen the stroke past 90 mm, and the stop is a mechanical end stop only - it does not hold or brake a load if air is lost. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome plated 16 mm rod and threaded aluminium covers. FA flange, LB foot and FTC brackets bolt to the standard face, and I/Y knuckles fit the male rod thread. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots for end-of-stroke detection. Air supply must be filtered to 40 um; proof pressure is 1.5 MPa (215 psi) and temperature range -20 to +70 C.
