This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X35-40SB, 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 ACPJ16X35-40SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X35-40SB is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X35-40SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X35-40SB
The ACPJ16X35-40SB is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 35 mm stroke anywhere within the ordered 40 mm window, giving a usable range of 0-35 mm. Air drives the rod in both directions, a fixed TPU bumper sits at each end, and the male-threaded 8 mm rod (the B code) bolts straight to I/Y knuckles. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those figures rise to 140.7 N and 105.6 N.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs, guards and pick stations where a full-length body will not fit. The hard-anodized aluminium body carries the S45C hard-chrome rod, ports are M5x0.8, and the fitted -S magnet accepts CMSE / DMSE reed or solid-state switches for end-of-stroke sensing. In practice the 100.5 N push translates to roughly 60 N (about 6 kg) of usable work at 0.5 MPa, and it lifts about 5 kg vertically with a 2:1 margin. Note: this model is discontinued - the current-production drop-in is the ACEJ16X35 (same bore, stroke and force class); confirm ISO 21287 mounting dimensions before swapping, since the ACP series is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X35-40SB (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 ACPJ16X35-40SB Is Used
Small-part ejection from plastic molds
The 100.5 N push at 0.5 MPa is enough to kick light molded caps or bushings off the ejector side of a small tool, and the 0-35 mm adjustable range lets the setter dial the exact eject distance on the bench.
Go / no-go clamp on an electronics test fixture
A PCB or connector assembly under about 6 kg of clamp load holds fine at 0.5 MPa; the fitted magnet with a CMSE switch confirms the clamp reached its trimmed end position before the test starts.
Product stopper on a compact conveyor line
The male-threaded 8 mm rod drives a stop blade that rises to halt bottles or cartons; the short body fits under low guard rails where an ISO 15552 profile cylinder would overhang the frame.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X35-40SB with the ACEJ16X35-40SB
Size by force: bore 12 delivers 56.5 N push at 0.5 MPa and bore 20 delivers 157.1 N, so the 16 mm bore at 100.5 N sits between them for light clamping and part placement. If your part weighs near 5 kg or less and lifts vertically, this bore covers it with margin; heavier loads should step up to bore 20. The 40 mm adjust window suits fixtures where the final extend position is tuned on the machine - remember the stop is a mechanical end stop, not a mid-stroke lock, so the piston drifts if air is lost. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet pairs with CMSE / DMSE switches. Order the ACEJ16X35 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X35-40SB
- ✓ 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 ACPJ16X35-40SB 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 is a 40 mm adjustment window: an external stop screw shortens the 35 mm extend stroke by up to 40 mm, so the working range is 0-35 mm. It shortens the stroke only - it never extends it past 35 mm, and it is a mechanical end stop, not a load-holding lock, so the rod still drifts on air loss. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends.
The ACPJ family is out of production; the current-production drop-in is the ACEJ16X35, which swaps the P for an E and matches the same 16 mm bore, 35 mm stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, because the ACP series was DIN-standard. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, FA/FB flange and LB foot mountings bolt to the standard face, and this unit carries the optional -S magnet so CMSE / DMSE reed or solid-state switches can be mounted for position sensing.
