Airtac STA Single Acting Compact Guided Cylinder STA16X5B
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA16X5B is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø16mm bore and 5mm stroke. Air pulles the rod and an internal spring returns it, so one solenoid line drives the motion — ideal for short-stroke clamping and ejection in tight spaces.

About the Airtac STA Single Acting Compact Guided Cylinder STA16X5B
The AirTAC STA16X5B is a compact single-acting pull-type cylinder where air retracts the rod and an internal spring pushes it back out. It generates 66.4 N of net pull at 0.5 MPa, making it suitable for light tensioning duties. Because the quoted force is already net of the return spring, you can size directly to this 66.4 N value.
This specific SKU features a male M5x0.8 rod-end thread (-B option) on a 6 mm piston rod, replacing the default female thread. The short riveted body saves valuable axial mounting depth where a standard round-body cylinder will not fit. It operates at 50-500 mm/s and relies on a fixed NBR bumper to decelerate the stroke end.
Airtac STA Single Acting Compact Guided Cylinder STA16X5B Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA16X5B |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø16 mm |
| Stroke | 5 mm |
| Acting type | Single acting, pull type |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 male (B) |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 500 mm/s |
| Cushion | Fixed NBR bumper |
| Max standard stroke | Up to 30 mm |
Specifications follow the official AirTAC SDA-family datasheet. Single-acting types start at 0.2 MPa (the spring must be overcome). Confirm against the product label before installation.
Net Output Force (Ø16mm, Pull)
| Pressure | Pull force (net) |
|---|---|
| 0.5 MPa | 66 N |
| 0.7 MPa | 101 N |
These are NET output forces — the return-spring force is already deducted. Single-acting pull only; the spring performs the opposite stroke. Size with a safety margin.

Where the Airtac STA Single Acting Compact Guided Cylinder STA16X5B Is Used
Tension Return Pulleys
Pulls a cable or belt pulley inward with 66.4 N net force, letting the internal spring automatically extend the rod back to the open position.
Spring-Return Gate Latch
Holds a lightweight access gate closed by pulling the latch pin, safely reverting to the extended position upon venting to fail open.
Strip Hold-Down Clamp
Draws a thin metal or plastic strip down against a fixture using the male M5x0.8 thread, releasing tension instantly when air pressure drops.
Is the Airtac STA Single Acting Compact Guided Cylinder STA16X5B the Right Cylinder?
When sizing this 16 mm bore, compare it both ways: stepping down to the STA12 yields 32.4 N at 0.5 MPa, while stepping up to the STA20 provides 108.9 N. This STA16X5B provides a computed safe working load of roughly 40 N, or a vertical lift capacity of about 3.4 kg with a 2:1 safety margin.
Note the 5 mm stroke operates well under the 30 mm single-acting ceiling. Because the spring drives the rod out when air is released, this cylinder does not hold a mid-stroke load without live pressure. Confirm your requirements for the M5x0.8 port, male rod thread, and lack of a piston magnet (no -S option for sensing).
Quick checklist
- ✓ Net pull force at your working pressure
- ✓ Stroke ≤ 30 mm (single-acting limit)
- ✓ Single air line saves a valve/port
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa operating pressure.
- check Remember the spring performs the return stroke.
- check Avoid side load on the short piston rod.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac STA Single Acting Compact Guided Cylinder STA16X5B FAQ
The STA16X5B provides a net pull force of 66.4 N at 0.5 MPa and 101 N at 0.7 MPa. It requires an operating pressure of 0.2-1.0 MPa, as at least 0.2 MPa is needed to overcome the internal return spring.
Air pressure retracts the 6 mm rod, and the internal spring extends it when air is released. The spring drives the rod to its extended rest position on air loss, so it does not hold a mid-stroke load without live pressure.
