This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X70SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X70SB 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 ACP20X70SB
The AirTAC Airtac ACP Compact Cylinder ACP20X70SB is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X70SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X70SB
The ACP20X70SB is a double acting DIN-standard compact cylinder with a 20 mm bore and 70 mm stroke, delivering 157.1 N push and 117.8 N pull at 0.5 MPa (219.9 N / 164.9 N at 0.7 MPa). Its hard-anodized aluminium body with threaded aluminium covers and an S45C hard-chrome rod keeps the mounting length roughly half that of an ISO 15552 profile cylinder, so it slots into tight jig plates and guarding where a full-length body will not fit. The B code gives a male rod thread, and the S code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted directly on the body.
Practical sizing: at 0.5 MPa plan on roughly 94 N of usable push force (about 60% of the rating), which corresponds to lifting around 9 kg vertically - halve that to about 4 kg if you want a 2:1 margin on a real part. Note this model is discontinued; the current-production drop-in is the ACE20X70 in the ISO 21287 family, so confirm the mounting dimensions before swapping. Air supply is 0.15-1.0 MPa (22-145 psi), speed range 30-500 mm/s, with fixed TPU bumpers at both ends.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X70SB (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 ACE20X70SB 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 ACP20X70SB Is Used
Fixture clamping on CNC jigs
The 157.1 N push at 0.5 MPa clamps small aluminium or plastic workpieces in drilling and milling fixtures, with the 70 mm stroke clearing part loading space.
Push-off on packaging lines
With about 9 kg of vertical-lift equivalent, this bore nudges cartons or blisters off a conveyor lane at speeds up to 500 mm/s, and CMSE switches flag end positions.
Sample handling in lab automation
The short ISO 21287-class body fits inside compact analyser frames, lifting sample trays of roughly 4 kg with a 2:1 margin on the 70 mm stroke.
Replacing the Airtac ACP Compact Cylinder ACP20X70SB with the ACE20X70SB
For a 70 mm stroke in this force band, the 20 mm bore gives 157.1 N push at 0.5 MPa; step down to a 16 mm bore (100.5 N) for lighter clamping or up to a 25 mm bore (245.4 N) if your load sits near the usable 94 N working figure. Remember a plain cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. The male rod thread (B) suits I/Y rod knuckles, and the -S magnet on this unit supports CMSE / DMSE switches for end-of-stroke signalling. Order the ACE20X70 as the current replacement and verify ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE20X70SB
- ✓ 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 ACP20X70SB FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa that rises to 219.9 N push and 164.9 N pull, with a theoretical maximum of 32 kgf at 1.0 MPa. It is a double acting compact cylinder, 20 mm bore, 70 mm stroke, 10 mm rod with male thread, M5x0.8 port, operating on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s. The model is discontinued - the ACE20X70 is the current replacement.
The hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow gantries and slide tables. Because this unit carries the -S magnet, CMSE or DMSE switches mount on the body for position feedback. Fixed TPU bumpers decelerate the piston at both ends, and FA/FB flange, LB foot or CA/CB clevis brackets bolt to the mounting face. Confirm ISO 21287 dimensions when moving to the ACE20X70.
