AirTAC SSA Series Single-Acting Compact Cylinders
The AirTAC SSA series is a single-acting spring-return push compact cylinder spanning 12-63mm bores, built for space-saving clamping and lifting where air loss must fail-safe to retraction.
inventory_2196 models availableSeries Overview
The AirTAC SSA series is the single-acting push variant of the SDA compact thin cylinder line. Pneumatic pressure extends the rod while an internal spring returns it, ensuring a fail-safe retracted state on air loss. It features a space-saving riveted body with C-clip retention rather than a traditional tie-rod or ISO profile.
The range spans 8 bores from 12 to 63mm. Ports scale with size: M5x0.8 for 12-25mm, PT1/8 for 32-40mm, and PT1/4 for 50-63mm. Because it is single-acting, net extend force is the air force minus the return-spring force, which is lower than the double-acting SDA push at the same bore. A minimum pressure is required before motion.
Shared design includes a fixed NBR bumper for end-of-stroke deceleration and standard magnetic-switch grooves for position sensing using -S magnet options. The JIS single-acting push equivalent is ASQ. Choose the SSA when a spring can handle the return motion to save air and a valve position.

Typical Applications
Ejector Pins in Molding
Uses the fail-safe spring-return retraction to ensure ejector pins pull back automatically on air loss, preventing damage during mold closure.
Package Sorting Gates
The compact 12-25mm bore range provides short-stroke diverting action on conveyor lines while saving air by using the spring for the return stroke.
Pallet Clamping Stops
Applies the 50-63mm bore sizes to hold pallets securely in place, with the single-acting push design releasing the clamp immediately if pneumatic pressure drops.
How to Choose the Right Model
Size the SSA by calculating the required net extend force against your supply pressure, remembering to subtract the return-spring force. Use the 12-25mm bores for light gating and small clamps, and the 32-63mm bores for heavier lifting. Confirm the 5-point match: bore size, required stroke, port thread (M5x0.8, PT1/8, PT1/4), mounting style, and whether the -S magnet is needed for sensors.
Step out of the SSA series if you need double-acting motion (choose SDA), single-acting pull retraction (choose STA), or adjustable stroke cushioning (choose SDAJ). The fixed NBR bumper only decelerates the piston; if the load must hold position mechanically on air loss, use a separate rod brake or pilot check valve.
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
The SSA series spans 8 bores from 12 to 63mm. Ports are M5x0.8 for 12-25mm bores, PT1/8 for 32-40mm bores, and PT1/4 for 50-63mm bores. There are no 80 or 100mm options in this single-acting range.
The SSA is single-acting push (air extends, spring retracts). The SDA is double-acting. The STA is single-acting pull. The SDAJ offers adjustable stroke. The SSA saves air and a valve position by using a spring return.
No. The SSA is a compact thin cylinder with a riveted body and C-clip retention, not a tie-rod or ISO cylinder. The JIS single-acting push equivalent is ASQ.
Net extend force is the pneumatic air force minus the internal return-spring force. This results in lower push force than a double-acting SDA at the same bore. A minimum pressure is required to overcome the spring before motion begins.
