This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X50SBH — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X50SBH 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 ACP20X50SBH
The AirTAC Airtac ACP Compact Cylinder ACP20X50SBH is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 50mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X50SBH (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X50SBH
A double acting compact cylinder in the DIN-standard ACP series, the ACP20X50SBH delivers 157.1 N of push force and 117.8 N of pull at 0.5 MPa, rising to 219.9 N at 0.7 MPa, with a 50 mm stroke on a 20 mm bore. The SBH code carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke sensing, and the B code gives a male rod thread on the 10 mm rod. Air supply is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and speed runs 30-500 mm/s.
The hard-anodized aluminium body with an S45C hard-chrome rod keeps the short ISO 21287-class body roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into tight fixtures. Note this model is discontinued: the current-production drop-in is the ACE20X50, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. A fixed TPU bumper at each end softens end-of-travel only; it does not hold a load, so add a rod lock or pilot check valve where position must be kept.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X50SBH (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 ACE20X50SBH 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 ACP20X50SBH Is Used
Small jig clamping
The 157.1 N push at 0.5 MPa clamps light aluminium or plastic workpieces in drilling and small machining jigs, with the 50 mm stroke clearing part loading by hand.
Indexed slide with sensing
Because this SBH version carries the -S magnet, CMSE or DMSE switches confirm extend and retract positions on a 50 mm indexing slide inside a compact assembly head.
Carton push-off
A 50 mm stroke with about 9 kg of practical vertical capacity suits pushing small cartons or blisters off a conveyor lane in packaging machines where body length is limited.
Replacing the Airtac ACP Compact Cylinder ACP20X50SBH with the ACE20X50SBH
At 0.5 MPa this 20 mm bore pushes 157.1 N, which works out to roughly 94 N of usable force if you keep a 40% margin - about 9 kg held vertically with a 2:1 safety factor. Step down to the 16 mm bore (100.5 N push) for lighter pick-and-place, or up to the 25 mm bore (245.4 N) when the load grows. Both 20 and 25 mm bores share the same M5x0.8 port, so piping stays simple. Choose FA/FB flange, LB foot or CA/CB clevis mounting to suit the fixture, and remember the -S magnet is what enables CMSE / DMSE switch sensing. Since ACP is discontinued, order the ACE20X50 as the current replacement and verify the ISO 21287 mounting footprint first.
Replacement checklist
- ✓ Current-production ACE → ACE20X50SBH
- ✓ 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 ACP20X50SBH 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, with a theoretical maximum of 32 kgf at 1.0 MPa. It is a double acting 20 mm bore, 50 mm stroke compact cylinder with a 10 mm male-threaded rod, M5x0.8 ports, 0.15-1.0 MPa (22-145 psi) operating pressure, 30-500 mm/s speed and fixed TPU bumpers at both ends.
Order the ACE20X50, the ISO 21287 successor made by swapping the P for an E. It matches the same 20 mm bore, 50 mm stroke and force class, and accepts the same FA/FB flange, LB foot and CA/CB clevis mounting family. Because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions against your fixture before the swap. The ACE also takes the optional -S magnet for CMSE / DMSE switches.
