This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X45SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X45SB 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 ACPD Double Rod Compact Cylinder ACPD50X45SB
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X45SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 45mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X45SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X45SB
Double acting with a rod exiting both covers, the ACPD50X45SB delivers an identical 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa in each direction, since both strokes work on the rod-side area. The through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag. This 50 mm bore unit is discontinued; the current-production drop-in is the ISO 21287 ACED50X45 in the same bore, stroke and force class.
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, guarding and gantries. A fixed TPU bumper sits at both ends, speed runs 30-500 mm/s, and the hard-anodized aluminium body pairs with an S45C hard-chrome rod. Because the S code is fitted, CMSE / DMSE switches can be mounted for position feedback. At 0.5 MPa the 881.2 N rating works out to about 90 kgf, so plan on lifting roughly 45 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X45SB (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 (Ø50mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACPD Double Rod Compact Cylinder ACPD50X45SB Is Used
Press-fit bushing insertion
The symmetric 881.2 N output in both directions suits a gearbox housing line where bushings are pressed in on the forward stroke and the part is ejected on the return, with the 45 mm stroke matching the fixture depth.
Bidirectional pusher on a packaging line
A carton diverter on a snack-food conveyor needs equal push force either way; the through-rod keeps the pusher plate square under side load at 30-500 mm/s cycling speeds.
Position-monitored lift column
In a semiconductor tray handler, the fitted -S magnet drives CMSE or DMSE switches to confirm up and down positions, while the rear rod carries a second flag for redundant end detection.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X45SB with the ACED50X45SB
Size between bores: a 40 mm double-rod unit gives 571.8 N at 0.5 MPa, while a 63 mm bore reaches 1458.1 N, so the 50 mm class at 881.2 N sits squarely in the middle for clamping and press-fit work. Remember this cylinder drifts when air is lost - it never holds or brakes a load - so add a rod lock or pilot check valve where a held position matters. Mounting brackets from the FA/FB flange and LB foot family bolt to the standard face, and the male rod thread (B code) suits external knuckles. Order the ACED50X45 as the current replacement and confirm the ISO 21287 mounting dimensions before swapping, since the ACP follows the DIN standard.
Replacement checklist
- ✓ Current-production ACE → ACED50X45SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPD Double Rod Compact Cylinder ACPD50X45SB FAQ
As a double-rod cylinder, force is equal both ways because both strokes use the rod-side area: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, with a maximum of 179.7 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is 1/8". A practical vertical lift with a 2:1 margin is about 45 kg.
Order the ACED50X45, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 50 mm bore, 45 mm stroke and force class with a short body and compatible mounting family. Because the ACP was built to the DIN standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping, and check the rod-end interface since this model carries a male thread.
