This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X15-20SB, 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 ACPJ16X15-20SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X15-20SB is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 15mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X15-20SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X15-20SB
The ACPJ16X15-20SB is a double acting compact cylinder with an adjustable extend stroke, built on the DIN-standard short-body format. Its 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, with a theoretical peak of 20.5 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: a stop screw trims the 15 mm extend stroke on site, giving a usable range of 0-15 mm without changing cylinders. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke sensing, and the B code gives a male rod thread.
Practically, plan on roughly 60 N of real work at 0.5 MPa (about 0.6 of the rated push), which lifts around 6 kg vertically before any margin is applied; halve that for a 2:1 safety factor and you can match parts up to about 3 kg. The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures. Note: this model is discontinued - the current-production replacement is ACEJ16X15, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X15-20SB (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 (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 ACPJ16X15-20SB Is Used
Small-part ejection on assembly fixtures
The 100.5 N push at 0.5 MPa is enough to kick stamped terminals or plastic caps off a nest, and the 0-15 mm trimmed stroke keeps the ejector pin travel exactly where the die needs it.
Position-verified clamping in test rigs
With the -S magnet fitted, CMSE or DMSE switches confirm the rod has reached the trimmed stop, letting an electronics tester verify clamp closure before a probe cycle starts.
Bottle-capping press on a packaging line
About 6 kg of vertical push at 0.5 MPa seats snap caps on cosmetic bottles, and the short body fits under a low guard where a full-length profile cylinder would not clear.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X15-20SB with the ACEJ16X15-20SB
Size both ways before committing: a 12 mm bore gives 56.5 N push at 0.5 MPa and may suffice for light indexing, while a 20 mm bore reaches 157.1 N if your fixture grows. Keep the 20 mm adjustment window in mind - it only shortens the extend stroke, it never extends past 15 mm, and the stop screw is not a mid-stroke lock, so the piston still drifts on air loss. Mounting uses FA/FB flanges or LB feet plus I/Y rod knuckles on the ISO 21287 face. Since ACPJ16X15-20SB is discontinued, order ACEJ16X15 as the drop-in successor and verify the ISO 21287 mounting dimensions against your existing holes.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X15-20SB
- ✓ 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 ACPJ16X15-20SB FAQ
At 0.5 MPa the 16 mm bore 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. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed range 30-500 mm/s, temperature -20 to +70 C, and the air must be filtered to 40 um. The rod is 8 mm with a male thread (B code) and the port is M5x0.8.
The -20 code orders a 20 mm adjustment window: an external stop screw shortens the 15 mm extend stroke anywhere within that window, giving 0-15 mm of usable travel. The fixed TPU bumpers at both ends only decelerate the piston at the ends - they never lock or hold a load. The ACPJ family is discontinued; the current-production drop-in is ACEJ16X15 in the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before you swap.
