This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ASE50X5SB, 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 ASP50X5SB
The AirTAC ASP Single Acting Guided Compact Cylinder ASP50X5SB is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø50mm bore and 5mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE50X5SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP50X5SB
The ASP50X5SB is a single acting push cylinder with spring return: air extends the 16 mm rod and the internal spring retracts it, so only one air line is needed and the rod sits retracted whenever pressure drops below the 0.2 MPa minimum. This 50 mm bore unit delivers 875.5 N of push at 0.5 MPa and 1268.2 N at 0.7 MPa, both already net of the spring, through a 1/8" port. The B code gives a male rod thread, and the S code means the optional magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted directly on the body.
Built on the ISO 21287 compact format, the hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which makes a 5 mm stroke like this easy to tuck into clamping fixtures and slide blocks. A fixed TPU bumper at each end absorbs end-of-travel shock. Note that the ASP family is discontinued; the current-production direct is the ASE50X5, and you should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE50X5SB (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 ASP50X5SB Is Used
Short-throw ejection pin
The 5 mm stroke and 875.5 N push at 0.5 MPa are ideal for knocking small stamped parts off a press die face, with the spring retracting the pin the instant air is removed.
Fixture clamp confirmation
Clamp a drill jig lid with the male rod thread, then use the fitted magnet with a CMSE switch to signal that the clamp is fully seated before the machining cycle starts.
Bottle indexing nudge
On a filling line, the compact body fits between guide rails and nudges bottles into a pitch of a few millimetres, retracting automatically by spring between containers.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP50X5SB with the ASE50X5SB
At 875.5 N push at 0.5 MPa, this 50 mm bore sits between the 40 mm bore (556.8 N) and the 63 mm bore (1420.5 N), so step down to 40 mm if your load is under about 330 N of real work, or up to 63 mm if you need more margin. The 5 mm stroke is well within the standard range for this bore, so no made-to-order stroke is required. The male rod thread (B) suits fixtures that clamp directly onto the rod, and because the magnet is fitted via the S code, CMSE / DMSE switches give end-of-stroke confirmation. Remember the spring returns the rod home on air loss and will not hold a mid-stroke position. For new projects, order the ASE50X5 instead, as the ASP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ASE50X5SB
- ✓ 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 ASP50X5SB FAQ
Push is 875.5 N at 0.5 MPa and 1268.2 N at 0.7 MPa, both net of the return spring. It is a single acting push cylinder: air extends the rod and the spring retracts it, so on air loss the rod drives back to its retracted home position. Minimum working pressure is 0.2 MPa (28 psi), the operating range is 0.2-1.0 MPa (28-145 psi), proof pressure is 1.5 MPa (215 psi), and speed is 50-500 mm/s.
The ISO 21287 format body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight jigs and slides. This S-coded model carries the optional magnet, so CMSE or DMSE reed or solid-state switches mount directly on the aluminium body. Since the ASP is discontinued, confirm ISO 21287 dimensions and order the ASE50X5 as the current direct.
