This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X60-50SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X60-50SB 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 ACPJ Adjustable Compact Cylinder ACPJ12X60-50SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-50SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 60mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X60-50SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-50SB
The ACPJ12X60-50SB is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 60 mm stroke by up to 50 mm on site, giving a usable range of 10-60 mm. This 12 mm bore unit delivers 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 / 59.4 N at 0.7 MPa), with a theoretical peak of 11.5 kgf at 1.0 MPa. The 60 mm stroke exceeds the 50 mm standard maximum for bore 12, so it is a non-standard, made-to-order length. Note: this model is discontinued; the current-production replacement is the ACEJ12X60, so confirm ISO 21287 mounting dimensions before swapping because the ACPJ follows a DIN-standard footprint.
Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which makes it a strong fit for slim fixtures, guarding gates and compact pick stations. The -S code means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke sensing; the rod carries a male thread (B code) and the ports are M5x0.8. As a rule of thumb, plan for about 34 N (roughly 3.4 kgf) of real work at 0.5 MPa, which lifts about 1.7 kg vertically with a 2:1 margin. Operating window is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with fixed TPU bumpers at both ends.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X60-50SB (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 (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 57 N | 42 N |
| 0.7 MPa | 79 N | 59 N |
| Max (@1.0 MPa) | 12 kgf | |
The ACEJ12X60-50SB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-50SB Is Used
Small-parts ejection in assembly fixtures
The 10-60 mm trim range lets a jig builder dial the exact eject distance for connector or pin parts, with 56.5 N push at 0.5 MPa enough for light plastic components.
Position-verified clamping on test benches
Because the magnet is fitted, CMSE / DMSE switches confirm the rod has reached the trimmed stop - useful in electronics test rigs where every clamp cycle must be logged.
Compact press-fit of bushings
At 0.7 MPa the bore 12 cylinder pushes 79.2 N, enough to seat small nylon or brass bushings in tight housings where a full-length cylinder will not fit.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-50SB with the ACEJ12X60-50SB
Size up or down by force: the 16 mm bore gives 100.5 N push at 0.5 MPa, while this 12 mm bore gives 56.5 N - step down only if your load is under about 34 N of real work. The adjuster is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the piston still drifts if air is lost; do not use it to hold a load. FA/FB flange and LB foot mountings bolt to the standard face, and because the magnet is fitted (the -S code), CMSE / DMSE switches work out of the box. For new designs, order the ACEJ12X60 instead - this ACPJ12X60-50SB is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X60-50SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-50SB FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa push is 79.2 N and pull 59.4 N; theoretical maximum is 11.5 kgf at 1.0 MPa. The -50 code is a 50 mm adjustment window: the stop screw shortens the 60 mm stroke by up to 50 mm, so the usable extend range is 10-60 mm. The 60 mm stroke is a made-to-order length since bore 12 tops out at 50 mm standard.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into narrow fixtures and gantries. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly for end-of-stroke detection. It is discontinued, though - the drop-in successor is the ACEJ12X60, so verify ISO 21287 mounting dimensions before ordering.
