This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ20X60-20SB, 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.

The AirTAC ACPJ Adjustable Compact Cylinder ACPJ20X60-20SB is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 60mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X60-20SB (ISO 21287 ACE), in the same bore, stroke and force class.
The ACPJ20X60-20SB is a discontinued double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 60 mm stroke by up to 20 mm, giving a usable 40-60 mm range. The male rod thread (B code) suits knuckle brackets, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke sensing.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight pick-and-place gantries and fixture plates. The fixed TPU bumper at both ends only decelerates the piston; it never locks a load, so on air loss the rod drifts. Replacement is the current-production ACEJ20X60 - confirm ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X60-20SB (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.
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 N |
| Max (@1.0 MPa) | 24 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).
| ACPJ | DIN compact cylinder (adjustable-stroke, discontinued). |
|---|---|
| 20 | Bore size in mm. |
| ×60 | Stroke length in mm. |
| -20 | Adjustable stroke window (mm the extend stroke can be shortened on site). |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (double rod, adjustable stroke).
Side-shifts plastic caps off a 200 mm-wide belt at 30-500 mm/s; the male rod thread takes a Y knuckle for a swing-arm pusher.
The fitted -S magnet drives CMSE / DMSE switches so the PLC confirms the 60 mm eject stroke before the next part is indexed.
The 20 mm adjustable window covers jigs that need 40-60 mm of travel; the stop is a mechanical end stop, not a mid-stroke lock. FA/FB flange and LB foot mountings plus I/Y rod knuckles bolt to the standard face, and the fitted -S magnet pairs with CMSE / DMSE switches. Order the ACEJ20X60 as the current direct and verify ISO 21287 hole patterns first.
Replacement checklist
Theoretical maximum is 32 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
The -20 code is a 20 mm window: an external stop screw shortens the 60 mm extend stroke to any setting from 40 to 60 mm. It is a mechanical end stop only - it never holds a load on air loss. This ACPJ is discontinued; the current-production replacement is the ACEJ20X60, a direct in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, because the ACP is DIN-standard.
