This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X65SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X65SB 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 ACP Compact Cylinder ACP20X65SB
The AirTAC Airtac ACP Compact Cylinder ACP20X65SB is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 65mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X65SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X65SB
A double acting compact cylinder in the DIN-standard ACP series, the ACP20X65SB carries a 20 mm bore with a 65 mm stroke and a male-threaded 10 mm rod. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, rising to 219.9 N on the extend stroke at 0.7 MPa. The hard-anodized aluminium body and S45C hard-chrome rod run on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with a fixed TPU bumper at each end and a speed range of 30-500 mm/s.
The short ISO 21287-class body cuts mounting length by roughly half versus an ISO 15552 profile cylinder, so it slots into shallow slides and guarding where a full-length body will not reach. Because the S code is in this model, the magnet is fitted and CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling. Plan on about 94 N of usable push at 0.5 MPa, which corresponds to lifting roughly 8 kg vertically with a 2:1 margin. This model is discontinued; the current drop-in is ACE20X65, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X65SB (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 ACE20X65SB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACP Compact Cylinder ACP20X65SB Is Used
Small-parts ejection on assembly benches
The 157.1 N push at 0.5 MPa is enough to kick stamped terminals or moulded caps off a nest, and the short body fits under low bench frames.
Position-checked test fixtures
With the -S magnet fitted, CMSE or DMSE switches confirm clamp and release positions on a 65 mm stroke in electronics or medical-device test rigs.
Light vertical indexing in packaging machines
Lifts roughly 8 kg vertically with a 2:1 margin, matching small carton pushers or label-head drop strokes on cartoning lines.
Replacing the Airtac ACP Compact Cylinder ACP20X65SB with the ACE20X65SB
At 157.1 N push at 0.5 MPa, this 20 mm bore suits light clamping and transfer tasks; step down to a 16 mm bore (100.5 N) for tighter loads or up to a 25 mm bore (245.4 N) if the part weight grows. The 65 mm stroke sits inside the 100 mm standard limit for bore 20, so no made-to-order build is needed. The male rod thread (B code) pairs with I/Y knuckles, and FA/FB flange, LB foot or CA/CB clevis mounts bolt to the same face. Note that a plain cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. Order ACE20X65 as the current-production replacement.
Replacement checklist
- ✓ Current-production ACE → ACE20X65SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACP Compact Cylinder ACP20X65SB FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those rise to 219.9 N and 164.9 N. The theoretical maximum is 32 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-500 mm/s.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange, LB foot or CA/CB clevis mounts plus I/Y rod knuckles bolt straight to the face. Each end carries a fixed TPU bumper that only decelerates the piston - it never holds a load, so use a rod lock or pilot check valve where position must be kept. This model is discontinued; ACE20X65 is the current drop-in, so confirm ISO 21287 mounting dimensions first.
