This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X175-10B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X175-10B 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 ACPJ20X175-10B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X175-10B is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 175mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X175-10B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X175-10B
This is a double acting, adjustable-stroke compact cylinder built to the DIN-standard ACPJ format: a 20 mm bore driving a 10 mm hard-chrome S45C rod through a hard-anodized aluminium body. At 0.5 MPa it pushes with 157.1 N and pulls with 117.8 N; at 0.7 MPa those figures rise to 219.9 N and 164.9 N, with a theoretical ceiling of 32 kgf at 1.0 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and guarding where a full-length body will not fit. The 175 mm stroke is a made-to-order length - the standard maximum for this bore is 100 mm - so it is built to order rather than picked from shelf stock.
The -10 code gives a 10 mm adjustment window: an external stop screw trims the extend stroke anywhere within 165-175 mm, letting one cylinder serve several fixture positions without swapping hardware. As a rule of thumb, plan on about 94 N (roughly 9.6 kg of thrust) of real work at 0.5 MPa, or halve the 16 kgf vertical-lift equivalent for a 2:1 margin - about 8 kg of safe vertical lift. A fixed TPU bumper at each end decelerates the piston; it never locks or holds a load, and on air loss the piston drifts. Note this model is discontinued: the current-production drop-in is the ACEJ20X175, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X175-10B (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 ACEJ20X175-10B 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 ACPJ20X175-10B Is Used
Fixture clamping on CNC pallets
The 157.1 N push at 0.5 MPa holds small aluminium or plastic workpieces in drill and milling jigs, and the 10 mm trim window lets one cylinder cover slightly different part heights.
Product reject pusher on packaging lines
With about 8 kg of safe vertical-lift equivalent thrust, the rod kicks off-spec cartons or blisters off a narrow conveyor where a full-length body would overhang the frame.
Sample lift in compact lab automation
The 165-175 mm adjustable extend range and short ISO 21287-class body suit vertical sample lifting in enclosed analyzers, with the male rod thread taking a custom platform.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X175-10B with the ACEJ20X175-10B
Size by force first: at 0.5 MPa this 20 mm bore delivers 157.1 N of push, while the 16 mm bore gives 100.5 N and the next class up (32 mm) reaches roughly 322 N - step up if your jig needs more than about 94 N of usable work. The male rod thread (B code) suits external knuckles and tooling plates; mounting options are FA/FB flange and LB foot on the ISO 21287 face. This unit has no magnet fitted, so position sensing is impossible unless you order the -S version with CMSE / DMSE switches. For new builds, specify the ACEJ20X175 instead - it is the current replacement in the same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X175-10B
- ✓ 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 ACPJ20X175-10B FAQ
At 0.5 MPa: 157.1 N push and 117.8 N pull. At 0.7 MPa: 219.9 N push and 164.9 N pull. 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, temperature -20 to +70 C, air filtered to 40 um, port M5x0.8, rod 10 mm with male thread, and the extend stroke is trimmable within a 10 mm window (165-175 mm).
Only if the -S magnet code was ordered - this version has no magnet, so no CMSE or DMSE switch can be mounted. The ACPJ family is discontinued; the current-production replacement is the ACEJ20X175, a drop-in successor in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACPJ follows the older DIN-standard footprint.
