About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-20SB
A double acting ISO 21287 compact cylinder, the ACEJ63X50-20SB pairs a 63 mm bore with a 50 mm stroke that an external stop screw trims on site: the -20 window lets you set any extend stroke from 30 to 50 mm without swapping the unit. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa, with a theoretical ceiling of 317.9 kgf at 1.0 MPa. The hard-anodized aluminium body and S45C hard-chrome rod keep the short frame serviceable across 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, clamping fixtures and gantries where a full-length body cannot. Because the S code is ordered, the magnet is fitted and CMSE / DMSE reed or solid-state switches can be mounted anywhere along the body slots, and the B code gives a male rod thread for direct linkage attachment. As a rule of thumb, plan on roughly 930 N of usable push at 0.5 MPa, which lifts about 95 kg vertically - or about 47 kg with a 2:1 margin for a real part weight.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-20SB Is Used
Pneumatic press station
The 1558.6 N push at 0.5 MPa suits staking and light forming on aluminium brackets, with the 30-50 mm adjustable window tuned per die.
Fixture clamping on machining lines
FA flange mounting and the male rod thread let the cylinder clamp cast housings in CNC fixtures, with CMSE switches confirming clamp state.
Palletizer part pusher
Short body fits between conveyor frames; the 50 mm stroke ejects cartons at up to 500 mm/s, trimmed down to 30 mm for narrow lanes.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-20SB the Right Cylinder?
At this force class the 63 mm bore sits between the 50 mm (981.7 N push at 0.5 MPa) and the 80 mm (2513.3 N push at 0.5 MPa); step down for lighter clamps, up when the 63 mm unit runs near its limit. The stop screw only shortens the extend stroke and is a mechanical end stop, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve if the load must stay put. FA flange or LB foot mountings bolt to the ISO 21287 face, and the fitted magnet means CMSE / DMSE switches work out of the box.
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 ACEJ63X50-20SB FAQ
Push is 1558.6 N and pull 1458.1 N at 0.5 MPa; 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 ordered stroke is 50 mm with a -20 adjustment window, so the extend stroke is trimmable to 30-50 mm via the external stop screw. Speed range is 30-500 mm/s and operating pressure 0.15-1.0 MPa (22-145 psi).
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, threaded aluminium covers, a fixed TPU bumper at both ends and a 16 mm hard-chrome S45C rod, about 50% shorter in mounting length than an ISO 15552 profile cylinder. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount in the body slots; the 1/8" port and FA/LB mountings drop into standard fixtures.
