This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X100-100SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X100-100SB 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 ACPJ20X100-100SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-100SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 100mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X100-100SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-100SB
This ACPJ20X100-100SB is a double acting compact cylinder with an adjustable extend stroke, now discontinued and replaced by the current-production ACEJ20X100. Air drives the piston both ways, and the -100 code gives a full 100 mm adjustment window: an external stop screw trims the extend stroke anywhere from 0 to 100 mm on site, so one cylinder serves several fixture depths. At 0.5 MPa the 20 mm bore pushes 157.1 N and pulls 117.8 N; at 0.7 MPa that rises to 219.9 N push and 164.9 N pull, with a theoretical 32 kgf at 1.0 MPa. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits tight jigs and gantries that reject full-length bodies.
Practical sizing: treat roughly 0.6 of the push rating as usable work, about 94 N at 0.5 MPa, which lifts roughly 9 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries an S45C hard-chrome 10 mm rod, fixed TPU bumpers sit at both ends, and speed runs 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi). The S code on this model fits the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke sensing. Before swapping to the ACEJ20X100, confirm the ISO 21287 mounting dimensions, since the ACP family is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X100-100SB (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 ACEJ20X100-100SB 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 ACPJ20X100-100SB Is Used
Fixture depth trimming on CNC jigs
The 0-100 mm adjustment window lets one cylinder serve several part heights on a milling fixture, with 157.1 N push at 0.5 MPa enough to seat aluminium workpieces against a hard stop.
Small-part ejection from stamping dies
A 20 mm bore punching finished blanks out of a die shoe uses the male rod thread for a direct nose fit; the fixed TPU bumper quiets the return at speeds up to 500 mm/s.
Gated inspection stations with position feedback
Because this model carries the -S magnet, CMSE / DMSE switches signal full extend on a vision-check gate, and the short body tucks behind machine guards where longer bodies will not fit.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-100SB with the ACEJ20X100-100SB
At 20 mm bore you sit mid-range in this family: the 16 mm bore delivers 100.5 N push at 0.5 MPa for lighter clamping, while stepping up gives more force if your fixture can take the body size. The 100 mm stroke matches the maximum standard stroke for this bore, so no made-to-order stroke is needed. The B code gives a male 10 mm rod thread and the port is M5x0.8; PT is the standard port thread. FA/FB flange or LB foot mounts bolt to the ISO 21287 face. Remember the stop screw trims the extend stroke only - it is not a mid-stroke lock, and on air loss the piston still drifts. Order the ACEJ20X100 as the current drop-in and verify mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X100-100SB
- ✓ 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 ACPJ20X100-100SB 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; theoretical maximum is 32 kgf at 1.0 MPa. The -100 code sets a 100 mm adjustment window: an external stop screw shortens the 100 mm extend stroke anywhere down to 0 mm. The stop is a mechanical end stop, not a load-holding brake - on air loss the piston still drifts. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with fixed TPU bumpers at both ends.
No - the ACPJ family is discontinued. The current-production replacement is the ACEJ20X100, the same bore, stroke and force class, but confirm the ISO 21287 mounting dimensions before swapping because the ACP is DIN-standard. This unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted for position sensing. Mounting uses FA/FB flange or LB foot on the ISO 21287 face, and the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder.
