Airtac ACED Double-acting Compact Cylinder ACED20X35B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X35B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø20mm bore and 35mm stroke, M5×0.8 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 ACED Double-acting Compact Cylinder ACED20X35B
The ACED20X35B is a double acting compact cylinder built to ISO 21287 with a rod leaving both covers, so the 20 mm bore delivers an equal 117.8 N in each direction at 0.5 MPa (164.9 N at 0.7 MPa) because both strokes work on the rod-side area. The male rod thread from the B code bolts straight to your tooling, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag. Running at 30-500 mm/s on air filtered to 40 um, it covers 0.15-1.0 MPa (22-145 psi) and -20 to +70 C.
The hard-anodized aluminium body with an S45C hard-chrome plated rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 35 mm stroke unit slots into tight pick-and-place gantries and fixture plates. A fixed TPU bumper at each end absorbs end-of-stroke shock. Note that no magnet is fitted on this code: order the optional -S version if you need CMSE or DMSE switch position sensing.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 N |
| Max (@1.0 MPa) | 24 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACED Double-acting Compact Cylinder ACED20X35B Is Used
Fixture clamping on CNC pallets
The symmetric through-rod clamps workpieces from both sides of a machining fixture, and the 117.8 N per side at 0.5 MPa is enough for light aluminum or plastic parts in a 35 mm clamp window.
Push-pull transfer slides
Equal force in both directions makes the ACED20X35B ideal for reciprocating small-part slides on electronics assembly lines, where the back rod drives a position flag between two CMSE or DMSE switches on a -S unit.
Bench-top press and rivet stations
With about 7 kg of practical working force and a short ISO 21287 body, this cylinder fits compact manual press heads and light staking rigs where a full-length profile cylinder will not clear the frame.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X35B the Right Cylinder?
At 117.8 N per direction at 0.5 MPa, the 20 mm bore sits between the 16 mm size (75.4 N) and the 25 mm size (206.2 N) in the same compact family. As a working rule, plan on roughly 70 N of real push - about 7 kg - rather than the full rating, and remember the piston will drift if air is lost, so add a rod lock or pilot check for a held load. Choose FA flange, LB foot or FTC brackets plus I or Y rod knuckles to suit the fixture, and step up to the -S code only when CMSE or DMSE sensing is required.
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 ACED Double-acting Compact Cylinder ACED20X35B FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area of the 20 mm bore: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, equal push and pull. The maximum force at 1.0 MPa is 24.0 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA flange, LB foot or FTC brackets plus I and Y knuckles bolt to the standard face. A fixed TPU bumper at each end absorbs end-of-stroke shock. Switches are not possible on this code as delivered: the magnet is the optional -S code, which enables CMSE and DMSE sensors.
