This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X100-10SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X100-10SB 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 ACPJ20X100-10SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-10SB 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 ACEJ20X100-10SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-10SB
Double acting and adjustable, the ACPJ20X100-10SB pushes 157.1 N and pulls 117.8 N at 0.5 MPa (219.9 N push at 0.7 MPa) from a 20 mm bore with a 100 mm stroke. The -10 code gives a 10 mm adjustment window: an external stop screw trims the extend stroke anywhere in a 90-100 mm range, so one cylinder serves several fixture positions. The male rod thread (B code) and the -S magnet are both on this unit, so CMSE / DMSE switches can be added for end-of-stroke sensing. Note this model is discontinued; the current-production replacement is ACEJ20X100.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters inside compact gantries and guarding. A fixed TPU bumper sits at both ends and the hard-anodized aluminium body carries an S45C hard-chrome rod. For sizing, expect about 94 N (roughly 9.6 kgf) of usable push at 0.5 MPa, which lifts about 8 kg vertically with a 2:1 margin. Running spec: 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, air filtered to 40 um.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X100-10SB (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 ACEJ20X100-10SB 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 ACPJ20X100-10SB Is Used
Fixture clamping on a CNC pallet
The 90-100 mm trim range lets one cylinder clamp both short and tall workpieces on a machining pallet, with the male rod thread taking a custom clamp arm.
Packaging line reject pusher
At 157.1 N push at 0.5 MPa the cylinder kicks off-spec cartons off a conveyor lane, and the fitted -S magnet with a DMSE switch confirms the return stroke.
Lab sample press station
About 8 kg of vertical lift with a 2:1 margin suits pressing sample vials into racks, while the compact body fits under a benchtop guard.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-10SB with the ACEJ20X100-10SB
At 157.1 N push at 0.5 MPa this 20 mm bore sits between the 16 mm bore (100.5 N) and the 32 mm class above it. Choose the 16 mm bore when your jig needs less than about 60 N of working force; step up a bore when the part weight or breakout friction approaches the 94 N usable figure. The stop screw only shortens the extend stroke and does not lock the piston - on air loss the rod still drifts, so add a separate clamp if you must hold position. LB foot or FA/FB flange mounting bolts to the standard face, and the optional -S magnet (fitted here) enables CMSE / DMSE switch sensing. Before ordering, confirm ISO 21287 mounting dimensions and specify ACEJ20X100 as the current drop-in.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X100-10SB
- ✓ 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 ACPJ20X100-10SB 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 -10 code is a 10 mm adjustment window: a stop screw shortens the 100 mm extend stroke, giving a usable 90-100 mm range. It is a mechanical end stop only - it never holds a load if air is lost. The model is discontinued; order ACEJ20X100 as the replacement.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange or LB foot mounting on the standard face and a fixed TPU bumper at each end. Because this unit carries the -S option, CMSE reed or DMSE solid-state switches mount directly in the body groove for end-of-stroke detection. Port is M5x0.8, speed range 30-500 mm/s, pressure 0.15-1.0 MPa (22-145 psi).
