This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X150-20SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X150-20SB 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 ACPJ20X150-20SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-20SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X150-20SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-20SB
This ACPJ20X150-20SB is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 150 mm stroke by up to 20 mm on site, giving a usable range of 130-150 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, with a theoretical peak of 32 kgf at 1.0 MPa. The 150 mm stroke exceeds the 100 mm standard limit for this bore, so it is a made-to-order build.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters in slim gantries and guarded cells. Because the -S magnet is fitted, CMSE or DMSE reed and solid-state switches can be mounted directly on the hard-anodized aluminium body. As a rule of thumb, plan for about 94 N (roughly 9.6 kg) of real vertical work at 0.5 MPa, or lift about 8 kg with a 2:1 margin. Note this model is discontinued; the current drop-in is ACEJ20X150 - confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X150-20SB (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 ACEJ20X150-20SB 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 ACPJ20X150-20SB Is Used
Small-parts press station
The 157.1 N push at 0.5 MPa is enough to seat connectors or labels in electronics assembly, while the 20 mm window lets a technician dial the stroke between 130 and 150 mm without changing the cylinder.
Pick-and-place drop check
With the fitted -S magnet and a DMSE switch, a packaging machine can confirm the rod reached the trimmed end position on each 130-150 mm downstroke at 30-500 mm/s.
Long-reach divert arm
The made-to-order 150 mm stroke clears a 400 mm conveyor lane where a standard 100 mm compact body falls short, and the male rod thread takes a knuckle for the swing link.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-20SB with the ACEJ20X150-20SB
At 20 mm bore this sits above the 16 mm size (100.5 N push at 0.5 MPa) and below the next force class, so choose it when your jig needs roughly 150 N at 5 bar with a long 150 mm reach. The adjuster is a mechanical end stop for the extend stroke only - it does not hold a load if air is lost. The male M6x1.0 rod thread (B code) suits rod knuckles and tooling plates; FA/FB flange and LB foot mountings bolt to the standard face. If you need position feedback, this unit already carries the optional -S magnet for CMSE / DMSE switches. For new designs, order the current ACEJ20X150 instead and verify ISO 21287 dimensions.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X150-20SB
- ✓ 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 ACPJ20X150-20SB FAQ
Push is 157.1 N and pull is 117.8 N at 0.5 MPa; at 0.7 MPa push rises to 219.9 N and pull to 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. The -20 code gives a 20 mm adjustment window, so the 150 mm extend stroke can be trimmed anywhere in a 130-150 mm range via the stop screw. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the 150 mm stroke is a made-to-order length since the bore 20 standard maximum is 100 mm.
The ACPJ family is discontinued; the current-production drop-in is ACEJ20X150, which matches the same bore, stroke and force class. Because the ACPJ is DIN-standard rather than ISO 21287, confirm the mounting dimensions before swapping. This particular unit carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be clamped to the body for end-of-stroke signalling.
