This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X160-50B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X160-50B 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 ACPJ20X160-50B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-50B 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 ACEJ20X160-50B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-50B
This ACPJ20X160-50B is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 160 mm stroke down by up to 50 mm on site, giving a usable 110-160 mm range. AirTAC has discontinued the ACPJ family, and the current-production drop-in is the ACEJ20X160 (ISO 21287), so confirm mounting dimensions before ordering.
The 20 mm bore delivers 157.1 N push and 117.8 N pull at 0.5 MPa, rising to 219.9 N at 0.7 MPa, with a theoretical ceiling of 32 kgf at 1.0 MPa. In practice plan on roughly 94 N of real work at 0.5 MPa (about 0.6 of the push rating), which vertically lifts about 9 kg with a 2:1 margin. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, the hard-anodized aluminium body carries an S45C hard-chrome 10 mm rod, and the 160 mm stroke is a made-to-order length since bore 20 tops out at 100 mm as a standard stroke.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-50B (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 ACEJ20X160-50B 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 ACPJ20X160-50B Is Used
Bench-top press fixture
The 157.1 N push at 0.5 MPa suits light crimping and marking on small aluminium brackets, with the 50 mm window letting you dial the press point between 110 and 160 mm.
Carton ejector on a packing line
A 160 mm reach pushes filled cartons off a conveyor lane; trimming the stroke with the stop screw prevents overtravel into the guard frame.
Sample lift in a lab indexer
With about 9 kg of vertical lift capacity at a 2:1 margin, the 20 mm bore raises small sample trays in compact analysis equipment where a full-length body will not fit.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-50B with the ACEJ20X160-50B
At 20 mm bore this sits in the mid force band: the 12 mm bore gives 56.5 N push at 0.5 MPa for lighter clamping, while stepping up adds cost you may not need if 157.1 N covers the job. The B code gives a male 10 mm rod thread and the port is M5x0.8, fixed by bore size. Note the 160 mm stroke is non-standard (bore 20 standard tops out at 100 mm), so it is built to order. FA/FB flange and LB foot mountings bolt to the ISO 21287 face. The adjuster is a mechanical end stop only - on air loss the piston still drifts, so it never holds a load mid-stroke. If you need position sensing, order the -S variant with the optional magnet for CMSE / DMSE switches; this unit has no magnet fitted. For new projects, specify the ACEJ20X160 instead.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-50B
- ✓ 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 ACPJ20X160-50B FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those rise to 219.9 N push and 164.9 N pull. The theoretical maximum is 32 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is M5x0.8. The 160 mm stroke is made to order because the bore 20 standard maximum is 100 mm.
The -50 code is a 50 mm adjustment window: an external stop screw shortens the extend stroke anywhere in the 110-160 mm range, and a fixed TPU bumper decelerates the piston at each end. It is a mechanical end stop, not a mid-stroke lock. The ACPJ is discontinued; the current-production replacement is the ACEJ20X160 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. FA/FB flange and LB foot mountings fit the standard face, and the optional -S magnet enables CMSE / DMSE switches.
