Airtac STA Single Acting Compact Guided Cylinder STA16X30B
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA16X30B is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø16mm bore and 30mm 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 STA16X30B
The AirTAC STA16X30B is a compact single-acting pull-type cylinder, meaning air pressure retracts the 6 mm rod while an internal spring extends it back out when exhaust occurs. At 0.5 MPa it generates 66.4 N of net pull, reaching 101 N at 0.7 MPa. Because the spring force is already subtracted, you can size directly to these net values for your tensioning or return-to-open tasks.
This 16 mm bore unit features a 30 mm stroke, sitting right at the maximum standard stroke ceiling for the STA family. The short riveted body drastically reduces axial mounting depth compared to round-body alternatives, fitting easily into cramped machinery. It uses a fixed NBR bumper to decelerate the stroke end rather than an adjustable cushion, and requires an operating pressure of 0.2-1.0 MPa to function properly.
Airtac STA Single Acting Compact Guided Cylinder STA16X30B Technical Specifications
| Model | Airtac STA Single Acting Compact Guided Cylinder STA16X30B |
|---|---|
| Series | STA compact single-acting cylinder |
| Bore size | Ø16 mm |
| Stroke | 30 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 STA16X30B Is Used
Clamp Retraction
Uses the 66.4 N net pull to draw a machining fixture clear of the part, letting the internal spring push the clamp open safely when air drops.
Diverter Gate Return
Pulls a sorting guide inward against belt flow, relying on the spring to snap the gate back to its open resting state during line stoppages.
Film Tensioning
Draws a wrapping film dancer arm back to maintain tension, with the male M5x0.8 rod end securing the pivot cleanly in tight packaging frames.
Is the Airtac STA Single Acting Compact Guided Cylinder STA16X30B the Right Cylinder?
When sizing this model, evaluate the adjacent bores: stepping down to the STA12 yields 32.4 N net pull at 0.5 MPa, while stepping up to the STA20 provides 108.9 N. Based on the 66.4 N rating at 0.5 MPa, a safe working load is approximately 40 N, which equates to a vertical lift of roughly 3.4 kg with a 2:1 safety margin.
Confirm this 16 mm bore, 30 mm stroke, and M5x0.8 air port suit your pneumatic layout. This specific SKU includes the -B option, giving you a male M5x0.8 piston rod thread instead of the default female M3x0.5. It lacks the -S magnet code, so it cannot accept reed or electronic switches. Remember the spring drives the rod to its extended rest position on air loss; it will not hold a mid-stroke load without external locking.
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 STA16X30B FAQ
This cylinder provides 66.4 N of net pull at 0.5 MPa and 101 N at 0.7 MPa. It requires an operating pressure of 0.2-1.0 MPa, needing at least 0.2 MPa to overcome the internal return spring.
No, this specific SKU does not include the -S magnet code, so it cannot accept reed or electronic switches. You would need the STA16X30BS variant to enable sensing capabilities.
