Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-40SB
The AirTAC Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-40SB is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø63mm bore and 55mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-40SB
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ63X55-40SB delivers 1558.6 N push and 1458.1 N pull at 0.5 MPa, rising to 2182.1 N at 0.7 MPa. The 63 mm bore drives a 16 mm hard-chrome S45C rod through a 55 mm stroke that the external stop screw trims anywhere in the ordered 40 mm window, giving a usable range of 15-55 mm without changing hardware.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into dense palletizer frames and weld fixtures. Because the -S magnet is fitted, CMSE or DMSE reed and solid-state switches clamp straight onto the body slot for end-of-stroke signalling, and the male rod thread (B code) accepts standard rod accessories.

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 ACEJ63X55-40SB Is Used
Weld fixture clamping
The 1558.6 N push at 0.5 MPa clamps steel brackets in automotive weld jigs, while the 15-55 mm trim range lets one cylinder serve several part sizes.
Palletizer push-off
With about 79 kg of vertical-lift equivalent, the 63 mm bore ejects cartons from conveyor stops in distribution centres at speeds of 30-500 mm/s.
Press-assist die setting
The male rod thread and FA flange mounting suit short-stroke die cushioning replacement in stamping shops, with CMSE switches confirming full seat via the fitted magnet.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-40SB the Right Cylinder?
At 0.5 MPa this bore pushes 1558.6 N, so plan on roughly 935 N (about 95 kg) of real work force and expect it to lift around 79 kg vertically, or about 40 kg with a 2:1 margin. If your load is lighter, the 50 mm bore gives 981.7 N push at 0.5 MPa; if heavier, the 80 mm bore reaches 2513.3 N. Note the stop screw is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so add a separate valve or lock for load holding. FA flange or LB foot mounts bolt to the ISO 21287 face, and PT ports take standard fittings.
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 ACEJ63X55-40SB 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, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -40 code sets a 40 mm adjustment window: an external stop screw shortens the 55 mm extend stroke by up to 40 mm, so the working range is 15-55 mm. It shortens the stroke only and acts as an end stop, not a mid-stroke lock.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends absorbing end-of-stroke energy. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches mount in the body slot for position feedback. FA flange and LB foot mounts, plus I and Y rod knuckles, bolt to the standard face; the 1/8" port takes PT thread fittings.
