This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X90-50B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X90-50B 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 ACPJ16X90-50B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X90-50B is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 90mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X90-50B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X90-50B
The ACPJ16X90-50B is a double acting, adjustable-stroke compact cylinder (now discontinued) with a 16 mm bore and a 90 mm stroke trimmed by a 50 mm window. Air works on both sides of the piston: it pushes 100.5 N and pulls 75.4 N at 0.5 MPa, rising to 140.7 N on the extend stroke at 0.7 MPa. The hard-anodized aluminium body in the ISO 21287 short format takes up roughly half the mounting length of an ISO 15552 profile cylinder, so it slots into cramped jigs and guarding where a full-length body will not fit.
The 90 mm stroke exceeds the 75 mm maximum standard stroke for a 16 mm bore, so this unit is made to order. The male rod thread (B code) is an 8 mm rod ending in an external male thread for direct knuckle or fixture attachment. In practice, plan on about 60 N of usable push at 0.5 MPa (roughly 6 kg of vertical lift with a 2:1 margin), not the full 100.5 N rating. A fixed TPU bumper sits at both ends. Note: this model is discontinued; the current-production drop-in is the ACEJ16X90, and buyers should confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X90-50B (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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 75 N |
| 0.7 MPa | 141 N | 106 N |
| Max (@1.0 MPa) | 21 kgf | |
The ACEJ16X90-50B 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 ACPJ16X90-50B Is Used
Multi-variant jig clamping
One cylinder covers clamping positions from 40 to 90 mm of extend stroke across different part families on a small machining fixture, with the 60 N usable push holding light aluminium workpieces.
Carton ejector on a packing line
The short ISO 21287 body fits inside tight guarding beside a carton conveyor, pushing empty cartons off the lane at 30-500 mm/s with 100.5 N of extend force at 0.5 MPa.
Sample press in a lab automation cell
The male 8 mm rod thread drives a small pressing platen for sealing microplate foils, where the 50 mm trim window lets technicians dial the press height without shimming.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X90-50B with the ACEJ16X90-50B
Size both ways: if 100.5 N push at 0.5 MPa is more than your load needs, the ACPJ12 (56.5 N push at 0.5 MPa) saves space; if you need more, the ACPJ20 delivers 157.1 N at the same pressure. The 50 mm adjustment window lets one cylinder serve fixture variants needing anywhere from 40 to 90 mm of extend stroke. Remember the stop screw trims the extend stroke only - it is not a mid-stroke lock, so the rod will drift if air is lost. Mounting uses FA/FB flanges or LB feet on the ISO 21287 face, with I/Y rod knuckles for the male thread. This model is discontinued; order the ACEJ16X90 as the current replacement and verify mounting dimensions against the ISO 21287 datasheet.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X90-50B
- ✓ 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 ACPJ16X90-50B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa it pushes 140.7 N and pulls 105.6 N. The theoretical maximum is 20.5 kgf at 1.0 MPa. The -50 code gives a 50 mm adjustment window, so the stop screw trims the 90 mm extend stroke down to as little as 40 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the port is M5x0.8. The 90 mm stroke is a made-to-order length since the bore 16 standard maximum is 75 mm.
Only if the optional -S magnet was ordered - this ACPJ16X90-50B has no S code, so there is no magnet and no CMSE or DMSE switch can be mounted; order an -S variant if sensing is needed. The ACPJ family is discontinued. The current-production replacement is the ACEJ16X90 (ISO 21287), a drop-in in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to the DIN standard.
