This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X10-10B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X10-10B in place of this model. 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 ACPJ20X10-10B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X10-10B is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 10mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X10-10B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X10-10B
This is a double acting compact cylinder with an adjustable extend stroke, built to the DIN-standard ACP short-body format. The 20 mm bore delivers 157.1 N push and 117.8 N pull at 0.5 MPa, rising to 219.9 N push at 0.7 MPa, with a theoretical peak of 32 kgf at 1.0 MPa. The -10 code gives a 10 mm adjustment window: a stop screw trims the 10 mm extend stroke on site, so the usable range is 0-10 mm. Note this model is discontinued; the current-production replacement is ACEJ20X10.
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 pick-and-place heads and small fixtures. Plan on roughly 94 N of real work at 0.5 MPa (about 0.6 of the push rating), which lifts about 4 kg vertically with a 2:1 margin. The male rod thread (B code) bolts to I/Y knuckles, and fixed TPU bumpers sit at both ends. Speed range is 30-500 mm/s. No magnet is fitted, so no CMSE / DMSE switch can be mounted unless you order the optional -S version.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X10-10B (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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 kgf | |
The ACEJ20X10-10B produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X10-10B Is Used
Small-part ejection
A 10 mm trimmed stroke with about 157 N push at 0.5 MPa is enough to kick a machined aluminium pin off a fixture nest without disturbing the part behind it.
Clamp-then-index slide
The 0-10 mm adjustable window lets a jig builder set the exact clamp travel on a rotary indexing table, with the male rod thread taking an I knuckle directly.
Carton hold-down tab
A packaging line can use the short body to press a folding tab over a carton flap; the fixed TPU bumper decelerates the rod at each end of the 10 mm travel.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X10-10B with the ACEJ20X10-10B
At 20 mm bore this sits above the 16 mm size (100.5 N push at 0.5 MPa) and below the next force class, so pick it when you need roughly 157 N of push in a 10 mm stroke. The adjuster is a mechanical end stop only: it shortens the extend stroke and does not hold a load if air is lost. Choose the FA flange or LB foot to match your fixture, and remember the male rod thread (B) when ordering knuckles. For new designs, spec ACEJ20X10 instead and confirm ISO 21287 mounting dimensions before swapping, since the ACP body is DIN-standard.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X10-10B
- ✓ 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 ACPJ20X10-10B FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa it pushes 219.9 N and pulls 164.9 N; the theoretical maximum is 32 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 10 mm extend stroke on site, giving a usable range of 0-10 mm. It is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. This model is discontinued; ACEJ20X10 is the drop-in replacement.
The hard-anodized aluminium body is an ISO 21287-class short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA flange and LB foot options. This version has no magnet fitted, so no CMSE / DMSE switch can be used; order the optional -S magnet code to enable switching. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, port M5x0.8.
