This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X35SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X35SB 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 ACP20X35SB
The AirTAC Airtac ACP Compact Cylinder ACP20X35SB is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X35SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X35SB
A double acting compact cylinder in the DIN-standard ACP series, the ACP20X35SB carries a 20 mm bore with a 35 mm stroke, a male rod thread on its 10 mm rod and an M5x0.8 port. 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 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 fixtures a full-length body cannot reach. Note the family is discontinued - ACE20X35 is the current-production successor.
The S code means the optional -S magnet is fitted on this unit, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the body for end-of-stroke signalling; without the S code there would be no magnet at all. The B code gives a male rod thread, and fixed TPU bumpers at both ends simply decelerate the piston - they never hold a load if air is lost, so add a rod lock or pilot check valve where a held position matters. For sizing, treat about 94 N (roughly 9.6 kg of force) as the usable push at 0.5 MPa, which lifts about 8 kg vertically with a 2:1 margin. Operating window is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, temperature -20 to +70 C.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X35SB (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 ACE20X35SB 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 ACP20X35SB Is Used
Small-parts ejection on rotary indexing tables
The 35 mm stroke and 157.1 N push at 0.5 MPa are enough to kick machined bushings or stamped clips off a fixture into a chute, and the short body fits between adjacent stations where a full-length cylinder would foul the dial plate.
Sample press in laboratory dispensing equipment
With about 8 kg of vertical lift capacity at a 2:1 margin, the 20 mm bore presses microplate lids or seals sample vials in compact benchtop analysers, and the fitted -S magnet drives a CMSE switch to confirm each cycle.
Carton flap hold-down on a packaging line
The male rod thread takes a knuckle to hold glue flaps down while hot-melt cures; 219.9 N at 0.7 MPa gives headroom, and the compact aluminium body mounts inside tight guard panels on the conveyor frame.
Replacing the Airtac ACP Compact Cylinder ACP20X35SB with the ACE20X35SB
At 157.1 N push at 0.5 MPa this 20 mm bore sits between the 16 mm bore (100.5 N) and the 25 mm bore (245.4 N); step up to 25 mm if your tooling mass creeps above about 8 kg of vertical lift, or drop to 16 mm for lighter gripper work. The male rod thread (B) suits knuckle and tooling attachments, while FA/FB flange, LB foot and CA/CB clevis mounts bolt to the same face family. If you need position feedback, this S-coded unit already carries the magnet for CMSE / DMSE switches. Since ACP is discontinued, order ACE20X35 as the drop-in and confirm the ISO 21287 mounting dimensions before the swap.
Replacement checklist
- ✓ Current-production ACE → ACE20X35SB
- ✓ 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 ACP20X35SB FAQ
At 0.5 MPa it delivers 157.1 N push and 117.8 N pull; at 0.7 MPa, 219.9 N push and 164.9 N pull, with a theoretical maximum of 32 kgf at 1.0 MPa. The ACP family is discontinued - the current-production replacement is ACE20X35, which matches the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping.
The short ISO 21287-class body cuts roughly 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange, LB foot and CA/CB clevis brackets bolt to the same face. The S in this model code means the optional -S magnet is fitted, so CMSE or DMSE reed or solid-state switches can be mounted for stroke detection; units ordered without the S code carry no magnet. The fixed TPU bumpers only decelerate at stroke ends - they do not lock the piston, so use a rod lock or check valve where a load must stay put.
