This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ASE32X25S, the same code under the new prefix. 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 ASP Single Acting Guided Compact Cylinder ASP32X25S
The AirTAC ASP Single Acting Guided Compact Cylinder ASP32X25S is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø32mm bore and 25mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE32X25S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP32X25S
A single acting push cylinder with spring return, the ASP32X25S extends its 12 mm rod on air and retracts it with the built-in spring, so one air line is all the plumbing it needs. At the 32 mm bore it delivers 352.5 N of push at 0.5 MPa (513.4 N at 0.7 MPa), already net of the spring, and it needs at least 0.2 MPa to overcome the spring. The -S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling. Note this model is discontinued: the current-production replacement is ASE32X25, 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, which is why it slots into tight fixtures, guarding and slide assemblies. A fixed TPU bumper at each end decelerates the rod, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the female M8x1.25 rod thread plus 1/8" PT port keep integration simple. Confirm ISO 21287 mounting dimensions before swapping from the DIN-standard original.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE32X25S (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 (Ø32mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 352.5 N |
| 0.7 MPa | 513.4 N |
Single-acting push: air extends the rod; the return spring retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.

Where the Airtac ASP Single Acting Guided Compact Cylinder ASP32X25S Is Used
Bench-top clamp fixture
Clamps small aluminium brackets against a hardened stop on a drilling jig; 352.5 N at 0.5 MPa holds the part while the spring retracts the rod for fast part changeover.
Reject pusher on a packaging line
The fitted magnet drives a CMSE switch that confirms full extension, so the PLC only releases a 25 mm kick-off stroke when the offload chute is truly clear.
Slide latch on a small press
Latches a guard interlock slide with one air line; the spring returns the latch home on power loss, a fail-safe default for machine safety circuits.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP32X25S with the ASE32X25S
Size by force first: at 0.5 MPa this 32 mm bore pushes 352.5 N net of the spring; step down to a 25 mm bore (210.1 N) for lighter clamps or up to a 40 mm bore (556.8 N) when the load grows. Remember the spring returns the rod to the retracted home position on air loss - it will not hold a mid-stroke position or support a hanging load. The 25 mm stroke suits short clamp-and-release moves at 50-500 mm/s. This unit ships with the -S magnet fitted for CMSE / DMSE switches and a female M8x1.25 rod thread; FA/FB flange, LB foot or CA/CB clevis mounting can be specified. Since ASP is discontinued, order ASE32X25 as the direct successor and verify the ISO 21287 mounting pattern.
Replacement checklist
- ✓ Current-production ACE → ASE32X25S
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ASP Single Acting Guided Compact Cylinder ASP32X25S FAQ
Net of the return spring it pushes 352.5 N at 0.5 MPa and 513.4 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 50-500 mm/s, temperature -20 to +70 C, and air filtered to 40 um. The bore is 32 mm, stroke 25 mm, rod 12 mm, port 1/8" PT, rod thread M8x1.25 female.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow fixtures and guarded spaces. This -S version carries the magnet, so CMSE or DMSE reed or solid-state switches mount directly on the body for end-of-stroke detection. The model is discontinued; ASE32X25 is the current direct - confirm ISO 21287 mounting dimensions before swapping.
