This model is discontinued

AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X40-40SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X40-40SB 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 ACPJ16X40-40SB

The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X40-40SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X40-40SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X40-40SB

A double acting compact cylinder with an adjustable extend stroke, the ACPJ16X40-40SB carries a 16 mm bore, 40 mm stroke and a 40 mm trimming window, so the stop screw can set any extend length from 0 to 40 mm on site. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those rise to 140.7 N and 105.6 N, with a theoretical peak of 20.5 kgf at 1.0 MPa. The male rod thread (B code) suits knuckle and tooling plates that bolt directly to the rod.

The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into cramped jigs and guarding where a full-length body cannot. Because the -S magnet is fitted on this model, CMSE or DMSE reed and solid-state switches can be added for end-of-stroke sensing. Note this model is discontinued: the current-production replacement is the ACEJ16X40, so confirm ISO 21287 mounting dimensions before swapping. As a rule of thumb, plan on roughly 60 N of usable push at 0.5 MPa, enough to lift about 5 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X40-40SB (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.

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X40-40SB Is Used

compress

Bench-top press fixture

The 100.5 N push at 0.5 MPa suits light riveting or marking on small aluminium brackets, with the 0-40 mm window letting the operator dial in the exact press depth per part.

sensors

Pick-and-check gantry

With the fitted -S magnet driving CMSE switches, the cylinder confirms full extension before a vision camera inspects PCB trays, all inside a body about 50% shorter than an ISO 15552 profile cylinder.

packaging

Carton flap tucker

On a packaging line the male rod thread takes a knuckle to fold flaps on small cartons, trimming the extend stroke down to match shallow box heights without changing cylinders.

Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X40-40SB with the ACEJ16X40-40SB

Size the bore by load: the 12 mm bore gives 56.5 N push at 0.5 MPa while the 20 mm bore reaches 157.1 N, so the 16 mm at 100.5 N sits between them for light clamping and indexing. Remember the stop screw trims the extend stroke only - it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. FA/FB flanges and LB feet bolt to the standard face, and with the -S magnet fitted CMSE/DMSE switches are ready to mount. Order the ACEJ16X40 as the current drop-in for this discontinued model.

Replacement checklist

  • ✓ Current-production ACE → ACEJ16X40-40SB
  • ✓ 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 ACPJ16X40-40SB FAQ

At 0.5 MPa it pushes 100.5 N and pulls 75.4 N. At 0.7 MPa the figures are 140.7 N push and 105.6 N pull. The theoretical maximum is 20.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed range 30-500 mm/s.

The -40 code gives a 40 mm window: an external stop screw shortens the 40 mm extend stroke to any length from 0 to 40 mm. It cannot lengthen the stroke past 40 mm, and it is not a load-holding brake. This model is discontinued; the ACEJ16X40 is the current-production replacement in the same bore, stroke and force class - confirm ISO 21287 mounting dimensions before swapping.
