This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X110-50SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X110-50SB 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 ACPJ20X110-50SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-50SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 110mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X110-50SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-50SB
The ACPJ20X110-50SB is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 110 mm stroke by up to 50 mm on site, giving a usable range of 60-110 mm. At the 20 mm bore it delivers 157.1 N push and 117.8 N pull at 0.5 MPa (219.9 N / 164.9 N at 0.7 MPa), with a male rod thread (B code) and the optional -S magnet fitted, so CMSE / DMSE switches can be mounted for end-of-stroke sensing. The 110 mm stroke is above the 100 mm standard maximum for this bore, so it is a made-to-order length.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jig plates and guarded gantries. A practical sizing rule: at 0.5 MPa roughly 94 N (about 0.6 of the push force) should be planned as real work, which is a vertical lift of about 9 kg - or roughly 4-5 kg with a 2:1 margin. Note this model is discontinued; the current drop-in is the ACEJ20X110, and buyers should confirm ISO 21287 mounting dimensions before swapping since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X110-50SB (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 ACEJ20X110-50SB 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 ACPJ20X110-50SB Is Used
Fixture clamping on CNC jigs
The 60-110 mm adjustable window lets a machinist trim the clamp stroke to the part without changing cylinders, with 157.1 N push at 0.5 MPa holding light aluminium workpieces.
Packaging line push-off
A 110 mm stroke ejects cartons or blisters from a conveyor lane; the compact short body fits inside tight guarding where a full-length profile cylinder will not.
Gated assembly stations
With the -S magnet fitted, CMSE / DMSE switches confirm extend and retract on a small pick-and-place or gate slide, cycling at 30-500 mm/s under PLC control.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-50SB with the ACEJ20X110-50SB
At 0.5 MPa this 20 mm bore pushes 157.1 N; step down to a 16 mm bore for 100.5 N or up to a larger bore if you need more than about 220 N at 0.7 MPa. The adjuster is a mechanical end stop for the extend stroke only - it does not lock the piston mid-stroke, so on air loss the rod still drifts and a separate holding method is needed for suspended loads. Mounting uses the FA/FB flange or LB foot on the ISO 21287 face, and the fitted -S magnet pairs with CMSE / DMSE switches. For new designs order the current-production ACEJ20X110 instead and verify the mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X110-50SB
- ✓ 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 ACPJ20X110-50SB 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 -50 code gives a 50 mm adjustment window, so the stop screw trims the 110 mm extend stroke anywhere down to 60 mm. The 110 mm stroke is a made-to-order length because the bore 20 standard maximum is 100 mm.
It has a hard-anodized aluminium body with an S45C hard-chrome rod, fixed TPU bumpers at both ends, an M5x0.8 port, male rod thread, and runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. The ACPJ family is discontinued; the current drop-in is the ACEJ20X110 - confirm the ISO 21287 mounting dimensions before swapping.
