About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-10S
The ACEJ63X70-10S is a double acting AirTAC compact cylinder built to ISO 21287, with a 63 mm bore and a 70 mm stroke that an external stop screw trims anywhere in a 10 mm window, giving a usable extend range of 60-70 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into presses, clamping fixtures and gantries where a full-length body simply will not fit.
This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clamped anywhere along the body for end-of-stroke signalling. The hard-anodized aluminium body pairs with a 16 mm S45C hard-chrome rod and a female M10x1.5 rod thread, and a fixed TPU bumper at each end absorbs end-of-stroke shock. In practice, plan for roughly 935 N (about 95 kg of force) of real work at 0.5 MPa, and expect it to lift about 79 kg vertically with a 2:1 margin.

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 ACEJ63X70-10S Is Used
Pneumatic press fixture
With 1558.6 N push at 0.5 MPa (2182.1 N at 0.7 MPa), this 63 mm bore drives light staking, riveting and press-fit heads on aluminium brackets, while the 10 mm window lets you dial the 70 mm stroke down to 60 mm for part variation.
Clamping on CNC machining fixtures
The short ISO 21287 body, roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, bolts inside tight jig walls, and the fitted -S magnet with a CMSE switch confirms the clamp is fully closed before the cycle starts.
Vertical lift on palletizer gantries
Halving the 158 kgf theoretical lift gives about 79 kg of vertical capacity with margin, enough to lower small cartons or trays onto conveyors; the LB foot mounting keeps the cylinder rigid on the gantry frame.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-10S the Right Cylinder?
Size check: a 50 mm bore pushes 981.7 N at 0.5 MPa, so if your load needs more than that but less than about 935 N of working force, the 63 mm is the right step up; go to an 80 mm bore (2513.3 N push) only when you genuinely need the extra thrust. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the rod will drift, so add a valve or external stop if you must hold position.
Mounting drops straight onto the ISO 21287 face: FA flange or LB foot brackets plus I and Y rod knuckles bolt on without adaptation. The fitted -S magnet works with CMSE / DMSE switches; air is filtered to 40 um, pressure runs 0.15-1.0 MPa (22-145 psi), and speed spans 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 ACEJ63X70-10S 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; theoretical maximum is 317.9 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 70 mm extend stroke by up to 10 mm, so the usable range is 60-70 mm. It cannot lengthen the stroke past 70 mm, and the stop is not a load-holding brake - the rod still drifts if air is lost.
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, a 16 mm hard-chrome S45C rod, a female M10x1.5 rod thread, a 1/8" PT port and fixed TPU bumpers at both ends. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount anywhere along the body slots; FA flange, LB foot and I/Y knuckle accessories bolt straight to the standard face.
