This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE20X20SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE20X20SB 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 ATP Single Acting Port Compact Cylinder ATP20X20SB
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP20X20SB is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø20mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE20X20SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP20X20SB
A single acting pull cylinder with spring return, the ATP20X20SB keeps its rod extended by spring force and retracts it with compressed air, delivering 88.1 N of pull at 0.5 MPa (135.2 N at 0.7 MPa), both figures already net of the spring. This 20 mm bore model is discontinued; the current-production drop-in is the ATE20X20, so confirm the ISO 21287 mounting dimensions before swapping. Its short body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarding where a full-length body cannot fit.
For sizing, treat about 53 N (roughly 5.4 kg of force) as the practical working pull at 0.5 MPa instead of the full 88.1 N rating, and expect it to lift about 4.5 kg vertically once a 2:1 margin is applied. The S code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted directly, and the B code gives a male rod thread with a PT air port. Air supply must be filtered to 40 um, pressure runs 0.2-1.0 MPa (28-145 psi), and rod speed spans 50-500 mm/s.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE20X20SB (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 | Pull force (spring return) |
|---|---|
| 0.5 MPa | 88.1 N |
| 0.7 MPa | 135.2 N |
Single-acting pull: the spring extends the rod; air retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.

Where the Airtac ATP Single Acting Port Compact Cylinder ATP20X20SB Is Used
Spring-extended jig clamp
Holds a machined aluminum bracket in a drilling fixture by default; 88.1 N of pull at 0.5 MPa retracts the clamp only while air is applied, so power loss leaves the part clamped.
Packaging gate retraction
Retracts a small deflector gate on a snack-food filling line at up to 500 mm/s, clearing a 20 mm product path each cycle with the spring snapping the gate back open.
Sample drawer on lab analyzer
Pulls a reagent sample drawer closed inside a compact diagnostic instrument, where the short ISO 21287 body fits a housing too tight for a full-length profile cylinder.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP20X20SB with the ATE20X20SB
At 20 mm bore this sits between the 16 mm size (53.3 N pull at 0.5 MPa) and the 25 mm size (170.9 N at 0.5 MPa), so step up a bore if your clamp or retract load exceeds about 53 N of real work. Remember the spring only returns the rod to its extended home position on air loss; it will not hold a mid-stroke position. The male rod thread (B) pairs with I/Y knuckles, and FA/FB flange, LB foot or CA/CB clevis mounts bolt to the ISO 21287 face. If you need position feedback, this S-coded unit already carries the optional -S magnet for CMSE / DMSE switches. Order the ATE20X20 as the current replacement and verify mounting dimensions against the datasheet.
Replacement checklist
- ✓ Current-production ACE → ATE20X20SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ATP Single Acting Port Compact Cylinder ATP20X20SB FAQ
This 20 mm bore, 20 mm stroke pull cylinder gives 88.1 N at 0.5 MPa and 135.2 N at 0.7 MPa, both net of the return spring. Working pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, temperature -20 to +70 C, speed 50-500 mm/s, rod 10 mm, male rod thread, M5x0.8 port and a fixed TPU bumper at both ends. It is discontinued; the ATE20X20 is the current replacement.
The S in ATP20X20SB means the optional -S magnet is fitted on this unit, so you can bolt CMSE reed or DMSE solid-state switches straight onto the body to signal rod position. Without the -S code there is no magnet and switches will not trigger. Note the spring only returns the rod fully extended on air loss, so switch points reflect the air-retracted position, not a held mid-stroke.
