Airtac STA Single Acting Compact Guided Cylinder STA16X15B
The AirTAC Airtac STA Single Acting Compact Guided Cylinder STA16X15B is a genuine single-acting COMPACT cylinder (single acting, pull type) with a Ø16mm bore and 15mm 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 STA16X15B
The AirTAC STA16X15B is a compact single-acting pull-type cylinder where compressed air retracts the 6 mm rod and an internal spring pushes it back out. It provides 66.4 N of net pull at 0.5 MPa, safely handling a working load of roughly 40 N or a vertical lift of about 3.4 kg with a 2:1 margin.
This unit features a male M5x0.8 piston rod thread and a short riveted body that minimizes axial mounting depth. It uses a fixed NBR bumper to decelerate the stroke end and requires a minimum operating pressure of 0.2 MPa to overcome the return spring.
Airtac STA Single Acting Compact Guided Cylinder STA16X15B Technical Specifications

| 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 |

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 STA16X15B Is Used
Tension Pull-Back
Pulls a tension belt or cable taut with 66.4 N net force at 0.5 MPa, releasing the load automatically when air pressure drops.
Normally-Open Gate
Holds a light access hatch open via spring force, using the 15 mm stroke to pull the gate closed securely upon pneumatic actuation.
Component Retraction
Withdraws a small 6 mm male-threaded probe or pin from a testing fixture using the 101 N net pull available at 0.7 MPa.
Is the Airtac STA Single Acting Compact Guided Cylinder STA16X15B the Right Cylinder?
When sizing this 16 mm bore actuator, compare its 66.4 N net pull at 0.5 MPa against adjacent bores: the STA12 yields 32.4 N, while the STA20 provides 108.9 N. This STA16X15B configuration includes a 15 mm stroke (under the 30 mm maximum), an M5x0.8 port, and the male M5x0.8 rod thread (-B option).
Because the spring constantly drives the rod to the extended rest position, this cylinder cannot hold a mid-stroke load without live air pressure. This specific SKU lacks the -S magnet option, meaning it cannot accept reed or electronic switches; choose the -S variant if position sensing is required.
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 STA16X15B FAQ
The net pull force is 66.4 N at 0.5 MPa and 101 N at 0.7 MPa. These figures already account for the internal return spring resistance, representing the actual usable pulling output.
Air pressure retracts the rod while the internal spring extends it to the resting position. It requires a minimum of 0.2 MPa operating pressure to overcome the spring, and the fixed NBR bumper absorbs end-of-stroke shock.
