This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ASE50X15SB, 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 ASP50X15SB
The AirTAC ASP Single Acting Guided Compact Cylinder ASP50X15SB is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø50mm bore and 15mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE50X15SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP50X15SB
Single acting push cylinder with spring return, the ASP50X15SB uses one air line to extend its 16 mm rod over a 15 mm stroke, and the internal spring pulls it back home when pressure drops. At 0.5 MPa it delivers 875.5 N of push net of the spring (1268.2 N at 0.7 MPa), and it needs just 0.2 MPa to overcome the spring. This ASP model is discontinued; the current-production replacement is the ASE50X15 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 clamping fixtures and guarded stations. Because the S code is in this model, the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can report end positions. A fixed TPU bumper sits at both ends, and the hard-anodized aluminium body carries an S45C hard-chrome rod.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE50X15SB (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 | Push force (spring return) |
|---|---|
| 0.5 MPa | 875.5 N |
| 0.7 MPa | 1268.2 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 ASP50X15SB Is Used
Press-fit bushing insertion
The 875.5 N push at 0.5 MPa seats small bushings or dowels into aluminium housings on a 15 mm working stroke, with the spring retracting the mandrel for part removal.
Carton hold-down on a packing line
A short-stroke pad presses carton flaps flat before taping; the spring return clears the zone instantly when the air signal drops, and CMSE switches confirm the down position.
Fixture clamp on a CNC jig
Clamps a machined bracket against a hard stop inside a tight jig where a full-length profile cylinder will not fit, using the male rod thread to pick up a custom clamp tip.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP50X15SB with the ASE50X15SB
Size against neighbours: the 40 mm bore gives 556.8 N at 0.5 MPa, while stepping up to 63 mm raises it to 1420.5 N, so pick the 50 mm when your clamping or ejecting load sits between those bands. Remember the spring drives the rod fully home on air loss, so this cylinder will not hold a mid-stroke position. Male rod thread (B code) and PT ports suit external rod accessories; if you need position sensing, this unit already carries the optional -S magnet for CMSE / DMSE switches. Before swapping in the ASE50X15, confirm the ISO 21287 mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ASE50X15SB
- ✓ 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 ASP50X15SB FAQ
Net of the return spring it pushes 875.5 N at 0.5 MPa and 1268.2 N at 0.7 MPa. Operating range is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof pressure; 0.2 MPa is the minimum to beat the spring. Speed runs 50-500 mm/s, air must be filtered to 40 um, and the 1/8" port depends on the 50 mm bore.
Order the ASE50X15, the current-production successor: swap the P for an E and you get the same 50 mm bore, 15 mm stroke and force class in a short ISO 21287 body. Confirm the ISO 21287 mounting dimensions against your fixture before the swap, since the ASP follows the DIN-standard footprint. Mounting options (FA/FB flange, LB foot, CA/CB clevis) and the optional -S magnet for CMSE / DMSE switches carry over in the replacement family.
