This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X160-75SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X160-75SB in place of this model. The ACE replacement is a current-production ISO 21287 compact cylinder in the same bore, stroke and force class, with a matching short body and the same mounting-accessory family, so it fits the same envelope. Confirm mounting-interface dimensions against the ACE datasheet before ordering.
Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-75SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-75SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 160mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X160-75SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-75SB
This is a double acting compact cylinder with an adjustable extend stroke: an external stop screw trims the 160 mm stroke down by up to 75 mm, giving a usable range of 85-160 mm. The 20 mm bore delivers 157.1 N push and 117.8 N pull at 0.5 MPa, rising to 219.9 N push at 0.7 MPa. Its short ISO 21287-style body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and guarding where a full-length body cannot. Note that the 160 mm stroke exceeds the 100 mm maximum standard stroke for this bore, so it is a made-to-order build.
The hard-anodized aluminium body carries a 10 mm S45C hard-chrome rod with a male thread (the B code), and fixed TPU bumpers sit at both ends. Because the S code is ordered, the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke sensing. A practical sizing rule: at 0.5 MPa plan on about 94 N of real work (roughly 60% of the push rating), which vertically lifts about 8 kg with a 2:1 margin. This model is discontinued; the current-production drop-in is the ACEJ20X160, and buyers should confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-75SB (ISO 21287) carries the same bore/stroke/force class; confirm mounting-interface dimensions against the ACE datasheet before installation. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 kgf | |
The ACEJ20X160-75SB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-75SB Is Used
Fixture clamp with trimmed stroke
On a small CNC jig, the stop screw trims the 160 mm extend stroke down to 85 mm so the clamp plate seats on the part without over-travel, delivering 157.1 N at 0.5 MPa.
Packaging line part pusher
Pushes cartons or trays off a narrow conveyor at 30-500 mm/s; the fitted magnet feeds CMSE switches to confirm extend position before the next cycle starts.
Light vertical lift in a test rig
With about 8 kg of vertical lift capacity at a 2:1 margin, it raises small fixtures or sensors in an automated inspection station within the 85-160 mm stroke window.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-75SB with the ACEJ20X160-75SB
Size the bore both ways: the 16 mm bore gives 100.5 N push at 0.5 MPa for lighter clamps, while the 25 mm class steps up well beyond this 20 mm bore's 157.1 N. Keep in mind the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston still drifts, so do not rely on it to hold a load. The male rod thread suits I/Y knuckles and FTC brackets, and FA flange or LB foot mounts bolt to the standard face. If your fixture needs a shorter standard stroke, the ACEJ20X160 is the current replacement to quote.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-75SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-75SB FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa it pushes 219.9 N and pulls 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. The -75 code sets a 75 mm adjustment window: a stop screw shortens the 160 mm extend stroke by up to 75 mm, so the working range is 85-160 mm. The stroke can only be shortened, never lengthened past the ordered stroke. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
No - the maximum standard stroke for the 20 mm bore is 100 mm, so 160 mm is a non-standard, made-to-order build. The ACPJ family is discontinued; the current-production drop-in is the ACEJ20X160, which matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard footprint. This unit carries the optional -S magnet, so CMSE / DMSE switches can be used for position sensing.
