AirTAC ATP Series Single-Acting Compact Cylinders
AirTAC ATP series single-acting pull compact cylinders, 12-100mm bore, spring-extend and air-retract, now replaced by the ATE series.
inventory_2175 models availableSeries Overview
The ATP series is a single-acting, spring-return pull version of the DIN-standard compact cylinder. A spring extends the rod to its home position, and compressed air retracts (pulls) it. This is not a tie-rod or ISO 15552 cylinder, and it is not a pushing cylinder. It is discontinued and replaced by the ISO 21287 ATE series; for example, ATP32X25 becomes ATE32X25.
The range covers 10 bores from 12 to 100 mm (12, 16, 20, 25, 32, 40, 50, 63, 80, 100) with short single-acting strokes: bore 12 up to 10 mm, bores 16-100 up to 25 mm. Minimum pressure is 0.2 MPa. Net pull force at 0.5 MPa spans about 26 N (bore 12) to 3484 N (bore 100), with speeds of 50-500 mm/s. The body is hard-anodized aluminium, the rod is S45C hard-chrome, and a two-way seal and fixed bumper are standard. A magnet option (-S) is available for magnetic switches.

Typical Applications
Fixture Clamping
In automated assembly fixtures, ATP cylinders pull clamps down to hold parts during drilling or riveting. The spring return keeps the clamp open when air is off.
Conveyor Stop Gates
On packaging lines, ATP cylinders retract a stop pin to release products. The spring extends the pin to block the next item, ensuring spacing.
Sorting Pusher (Pull)
In a warehouse sorting system, an ATP cylinder pulls a diverting arm to route parcels. The spring returns the arm to the home position, ready for the next cycle.
Valve Actuation
In process equipment, ATP cylinders pull a lever or linkage to actuate a small valve. The spring provides fail-safe return on air loss.
How to Choose the Right Model
Choose the ATP bore based on the required pull force at your operating pressure. For light loads, bores 12-25 mm provide 26-150 N at 0.5 MPa; for heavier pulls, bores 32-100 mm deliver up to 3484 N. Confirm the stroke needed (max 10 mm for bore 12, 25 mm for others) and the port thread. Select the -S magnet option if you need position sensing with magnetic switches.
Because the ATP is discontinued, step out to the ATE series (ISO 21287) for new designs. ATE offers the same bore range and is the direct replacement. For double-acting or push applications, consider the ACP or ACE series. Confirm five points before ordering: bore, stroke, port/thread, mounting style, and magnet -S option.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and available mounting space
- ✓ Port / thread type (PT / NPT / G)
- ✓ Sensor / magnet option (-S)?
- ✓ Side load — consider a guided model
Frequently Asked Questions
At 0.5 MPa, the net pull force (after the return spring) spans about 26 N for bore 12 to 3484 N for bore 100. Speed range is 50-500 mm/s. Minimum pressure is 0.2 MPa.
The main variant is the -S magnet option for magnetic switches. All ATP cylinders are single-acting pull with spring return and a fixed bumper. There is no adjustable cushion or double-rod version in this series.
Yes, the ATP series is discontinued. The direct replacement is the ATE series (ISO 21287). For example, ATP32X25 is replaced by ATE32X25. The ATE series offers the same bore range and similar performance.
No. The spring returns the rod to the extended home position, but it does not lock or brake mid-stroke. For load holding, use a mechanical lock, rod brake, or pilot check valve.
