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

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-10B
This is a double acting, adjustable-stroke compact cylinder in the discontinued ACPJ family: a 20 mm bore with a 100 mm stroke, a 10 mm male-threaded rod (B code) and M5x0.8 ports. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those rise to 219.9 N and 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. The stop screw trims the extend stroke by up to 10 mm on site, so the working range is 90-100 mm. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), from -20 to +70 C at 30-500 mm/s.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into narrow gantries and guarded assemblies where a full-length body will not reach. As a planning figure, treat about 94 N (0.6 of the 157.1 N push) as the realistic working force at 0.5 MPa, which corresponds to lifting roughly 4 kg vertically with a 2:1 margin. Fixed TPU bumpers sit at both ends, the hard-anodized aluminium body carries an S45C hard-chrome rod, and FA/FB flange or LB foot mounts bolt to the standard face. Note that this model is discontinued; the current-production drop-in is the ACEJ20X100, so confirm the ISO 21287 mounting dimensions before swapping. No magnet is fitted on this version (the optional -S code adds one for CMSE / DMSE switches).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X100-10B (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 ACEJ20X100-10B 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 ACPJ20X100-10B Is Used
Compact jig clamping
The 157.1 N push at 0.5 MPa clamps small aluminium brackets in drilling fixtures, and the 10 mm trim lets you set the exact clamp position inside a 90-100 mm envelope.
Narrow conveyor gating
With a body about 50% shorter than an ISO 15552 profile cylinder, the 100 mm stroke ejects or diverts small parts on tight conveyor lines where side space is limited.
Bench-top press positioning
The male-threaded 10 mm rod takes an I or Y knuckle for light pressing or sample feeding in lab and small-batch equipment, running 30-500 mm/s under PLC control.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-10B with the ACEJ20X100-10B
At 157.1 N push and 117.8 N pull at 0.5 MPa, this 20 mm bore suits clamping and positioning loads in the 5-9 kg class; step down to a 16 mm bore (100.5 N push) for lighter jigs or up to a 32 mm class body when more force is needed. The 10 mm window only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Match FA/FB flange or LB foot mounting to your fixture, and if you need end-of-stroke detection, order the -S magnet version with CMSE / DMSE switches instead of this non-magnet build. For new projects, specify the ACEJ20X100, the current replacement in the same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X100-10B
- ✓ 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 ACPJ20X100-10B 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 -10 code gives a 10 mm adjustment window: a stop screw shortens the 100 mm extend stroke on site, giving a usable 90-100 mm range. It is a mechanical end stop only - on air loss the piston still drifts, so it is not a load-holding brake.
This build has no magnet, so no switch can be mounted; the optional -S magnet code enables CMSE / DMSE reed or solid-state switches. The ACPJ family is discontinued, and the current-production drop-in is the ACEJ20X100 in the same 20 mm bore, 100 mm stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard footprint.
