AirTAC ACP Series Compact Cylinders
AirTAC ACP series compact cylinders are DIN-standard, double-acting, single-rod cylinders in 12-100mm bores, now replaced by the ACE series.
inventory_2788 models availableSeries Overview
The AirTAC ACP series is a DIN-standard compact cylinder family with a hard-anodized aluminum body, S45C hard-chrome rod, and aluminum covers threaded onto the body. It is a short, compact cylinder - not a tie-rod or ISO 15552 profile cylinder. Available in 10 bores from 12 to 100 mm, with rod diameters from 6 mm (bore 12) to 25 mm (bore 100). Ports range from M5x0.8 (bores 12-25) to 1/8 inch (bores 32-63) and 1/4 inch (bores 80-100).
All ACP cylinders are double-acting with a fixed bumper at both ends that decelerates the piston near stroke end - it does not lock or hold. A two-way grease-storing piston seal reduces friction. An optional magnet (-S) enables position sensing with switches. Operating pressure is 0.15-1.0 MPa, proof pressure 1.5 MPa, temperature -20 to +80 C, and speed 30-500 mm/s. Air quality should be 40 um filtered.
This series is discontinued. The direct replacement is the ISO 21287 ACE series, which shares the same bore, stroke, and force class. For example, ACP32X25 becomes ACE32X25. Confirm ISO 21287 mounting dimensions before ordering.

Typical Applications
Pick-and-Place Grippers
Compact ACP cylinders (bores 12-25 mm) fit into tight gripper mechanisms on assembly robots, providing quick, repeatable motion for small parts handling.
Packaging Machine Pushers
Bores 32-63 mm with 1/8 inch ports deliver moderate force to push cartons or pouches along a conveyor, with the fixed bumper reducing end-of-stroke impact.
Jig Clamping on Workstations
Larger bores (80-100 mm) supply high push force up to 3927 N at 0.5 MPa to clamp fixtures securely in manual or semi-automated workstations.
Stop Gates on Conveyors
Use a bore 40 or 50 ACP cylinder with magnet -S to actuate a stop gate, with the sensor confirming gate position for reliable sorting or diverting.
How to Choose the Right Model
To select within the ACP series, choose the bore based on required push force at your operating pressure. At 0.5 MPa, push force spans about 57 N (bore 12) to 3927 N (bore 100). For lighter loads, smaller bores (12-25 mm) with M5 ports suit compact fixtures; for heavier loads, larger bores (80-100 mm) with 1/4 inch ports provide higher force. If you need position sensing, add the -S magnet option for switch mounting.
Since ACP is discontinued, step out to the ACE series for current production. ACE is ISO 21287 compliant and offers the same bore/stroke/force class. For single-acting applications, consider ASP/ATP; for double-rod, ACPD; for adjustable stroke, ACPJ - all replaced by ACE family. Always confirm bore, stroke, port thread, mounting style, and magnet option when ordering.

Frequently Asked Questions
At 0.5 MPa, push force spans about 57 N (bore 12) to 3927 N (bore 100). Pull force is slightly lower due to the rod area. Choose the bore based on your required force at your operating pressure.
The ACP series includes ACPD (double rod) and ACPJ (adjustable stroke). ACPD gives equal force and speed in both directions; ACPJ allows stroke adjustment. All are double-acting with fixed bumpers. They are all discontinued and replaced by ACE equivalents.
No. ACP is a DIN-standard compact cylinder, not an ISO 15552 profile cylinder. It is discontinued. The replacement is the ISO 21287 ACE series, which matches bore, stroke, and force class. Confirm ISO 21287 mounting dimensions before ordering.
No. The fixed bumper only decelerates the piston near stroke end; it does not lock or hold. For load holding, use a mechanical lock, rod brake, or pilot check valve externally.
