This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X30-20SB, 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 ACPJ16X30-20SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X30-20SB is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 30mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X30-20SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X30-20SB
This double acting compact cylinder, the AirTAC ACPJ16X30-20SB, delivers 100.5 N push and 75.4 N pull at 0.5 MPa (140.7 N push at 0.7 MPa) from a 16 mm bore with a 30 mm stroke. Its hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into tight jigs, guards and gantries where a full-length body will not fit. Note that the ACPJ family is discontinued; the current-production drop-in is ACEJ16X30 in the same bore, stroke and force class.
The -20 code gives a 20 mm adjustment window: an external stop screw trims the extend stroke anywhere between 10 and 30 mm on site, so one cylinder covers several fixture positions. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing, and the B code gives a male rod thread. With 100.5 N at 0.5 MPa, plan on roughly 60 N (about 6 kg of vertical lift) of real work for a dependable margin. Speed range is 30-500 mm/s and the fixed TPU bumpers at both ends simply decelerate the piston at each end of travel.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X30-20SB (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 ACPJ16X30-20SB Is Used
Small-part ejection on assembly fixtures
The 10-30 mm trimmed extend stroke and 100.5 N push at 0.5 MPa suit knocking finished bushings or pins off a jig in electronics and small-mechanism assembly.
Position-verified clamping of PCB test nests
With the fitted -S magnet driving CMSE or DMSE switches, the 16 mm bore confirms clamp presence on test and burn-in nests without extra proximity sensors.
Light press-fit of bearings in watch and instrument work
About 6 kg of practical vertical push (60 N working load at 0.5 MPa) is enough for seating small bearings or snaps in instrument and watchmaking benches.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X30-20SB with the ACEJ16X30-20SB
Size between bores: a 12 mm bore pushes only 56.5 N at 0.5 MPa, while a 20 mm bore reaches 157.1 N, so the 16 mm at 100.5 N sits in the middle for light clamping and indexing. The stop screw is a mechanical end stop for the extend stroke only, not a mid-stroke lock, so the piston can still drift if air is lost. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and the male rod thread suits I/Y knuckles. Before ordering, confirm ISO 21287 mounting dimensions and consider the ACEJ16X30 replacement, since this ACPJ is a discontinued DIN-standard design.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X30-20SB
- ✓ 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 ACPJ16X30-20SB 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 16 mm bore has an 8 mm rod, M5x0.8 ports, PT body thread, male rod thread (B code), operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C and speed 30-500 mm/s. The -20 window trims the 30 mm extend stroke down to 10 mm.
An external stop screw shortens the extend stroke by up to 20 mm inside the ordered window, giving a usable 10-30 mm range; it cannot lengthen the stroke past 30 mm and it does not hold a load if air is lost. The ACPJ family is discontinued, so order the ACEJ16X30 as the current-production drop-in in the same bore, stroke and force class, and confirm the ISO 21287 mounting dimensions before swapping from the DIN-standard ACP footprint.
