This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X150-40B, the same code under the new prefix. 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 ACPJ16X150-40B
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X150-40B is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm 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 ACEJ16X150-40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-40B
This is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 150 mm stroke by up to 40 mm, giving a usable range of 110-150 mm on site. The 16 mm bore delivers 100.5 N push and 75.4 N pull at 0.5 MPa, rising to 140.7 N push at 0.7 MPa. The male rod thread (B code) bolts straight to I/Y knuckles on the ISO 21287 mounting face.
The 150 mm stroke exceeds the 75 mm standard maximum for bore 16, so it is a made-to-order build - plan lead time accordingly. Note the 150 mm body still saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it suits tight guards and gantries. At 0.5 MPa the push force equals roughly 10 kgf, so halved for margin it lifts about 5 kg vertically - match that to your part weight. This model is discontinued; the current drop-in is ACEJ16X150 (same bore, stroke and force class), and you should confirm ISO 21287 mounting dimensions before swapping because the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X150-40B (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 | Force (both ways) |
|---|---|
| 0.5 MPa | 75 N |
| 0.7 MPa | 106 N |
| Max (@1.0 MPa) | 15 kgf |
ACPJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-40B Is Used
Fixture clamping on CNC jigs
The 110-150 mm adjustable range lets one jig body serve several part heights; 100.5 N push at 0.5 MPa suits light clamping of aluminium brackets.
Product divert on packaging lines
A 150 mm stroke pushes cartons off a narrow conveyor, and the male rod thread takes a knuckle for a swing gate; the short body fits under low guarding.
Sample lift in lab automation
With about 5 kg of vertical lift capacity at a 2:1 margin, the bore 16 cylinder raises microplate stacks and small fixtures in compact analysers.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-40B with the ACEJ16X150-40B
Size against the neighbours: bore 12 gives 56.5 N push at 0.5 MPa and bore 20 gives 157.1 N, so pick 16 only if your load sits between those. The adjuster is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve for suspended loads. Mounting is FA/FB flange or LB foot; the optional -S magnet enables CMSE / DMSE switches, and without it no sensor can be fitted. For new builds order the ACEJ16X150, the current-production successor.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X150-40B
- ✓ 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 ACPJ16X150-40B 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; theoretical maximum is 20.5 kgf at 1.0 MPa. The -40 code gives a 40 mm adjustment window, so the 150 mm extend stroke can be trimmed anywhere in a 110-150 mm range. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
Yes: 75 mm is the standard maximum for a 16 mm bore, so 150 mm is a made-to-order stroke - expect a factory build rather than shelf stock. The ACPJ family itself is discontinued; the current-production drop-in is the ACEJ16X150 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
