Airtac ATQ Single Acting Thin Cylinder ATQ63X15SB
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ63X15SB is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø63mm bore and 15mm stroke. Air pulles the rod and an internal spring performs the opposite stroke, so one solenoid line drives the motion — ideal for short-stroke clamping and ejection in tight spaces.

About the Airtac ATQ Single Acting Thin Cylinder ATQ63X15SB
The AirTAC ATQ63X15SB is a 63mm JIS compact single-acting PULL cylinder. Air directed to one port retracts the rod, while an internal spring extends it upon exhaust. It delivers a theoretical pull of 1401.5N at 0.5MPa (1962.2N at 0.7MPa) before spring deduction. The return spring lowers net output, so verify exact net force from the datasheet.
This unit features a 15mm stroke, well under the 30mm maximum for this bore. A 0.2MPa minimum operating pressure is required to overcome the spring. It includes fixed NBR elastomer bumpers at each end for end-of-stroke impact absorption, rather than adjustable air cushions. The -S magnet enables position sensing with reed or electronic solid-state switches, and the -B option provides a male M18x1.5 rod-end thread for direct load coupling.
Airtac ATQ Single Acting Thin Cylinder ATQ63X15SB Technical Specifications
| Model | Airtac ATQ Single Acting Thin Cylinder ATQ63X15SB |
|---|---|
| Series | ATQ JIS compact single-acting cylinder |
| Bore size | Ø63 mm |
| Stroke | 15 mm |
| Acting type | Single acting, pull type |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 | Bumper |
| Max standard stroke | Up to 30 mm |
Specifications follow the official AirTAC ACQ-family datasheet. Single-acting types start at 0.2 MPa (the spring must be overcome). Confirm against the product label before installation.
Theoretical Output Force (Ø63mm, Pull)
| Pressure | Pull force (before spring) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa | 1962 N |
These are theoretical air-side forces; the return-spring force reduces the NET usable output. Single-acting pull only — the spring performs the opposite stroke. Confirm the net figure from the datasheet and size with a safety margin.

Where the Airtac ATQ Single Acting Thin Cylinder ATQ63X15SB Is Used
Heavy-Duty Tensioning
Pulls heavy webbing or sheet material taut in large metal forming lines, utilizing the spring-extend rest position to maintain baseline tension when air is removed.
Clamp Release Mechanism
Retracts large holding clamps on injection molding machines, allowing the internal spring to safely extend and open the clamp upon loss of air pressure.
Pallet Stopper Gate
Draws back a heavy stop gate on pallet conveyors, with the spring extending the rod to block flow during an emergency shutdown or compressed air failure.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ63X15SB the Right Cylinder?
For a 63mm bore, the ATQ63X15SB provides 1401.5N theoretical pull at 0.5MPa. If less force is acceptable, the 50mm bore offers 824.6N; no larger bore exists in this series. Since this is a single-acting spring-extend unit, travel is capped at 30mm. Applications requiring longer movement must switch to a double-acting ACQ cylinder. When ordering, confirm the 63mm bore, 15mm stroke, -S magnet, and -B male M18x1.5 rod thread.
Quick checklist
- ✓ Net pull force (after spring) at your 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 Handle the C-clip carefully; seat it fully in its groove.
- check Installation by qualified personnel per AirTAC docs.
Airtac ATQ Single Acting Thin Cylinder ATQ63X15SB FAQ
It has a 15mm stroke (max 30mm for bore 63). The theoretical pull is 1401.5N at 0.5MPa and 1962.2N at 0.7MPa before spring deduction. It requires a minimum 0.2MPa operating pressure to overcome the return spring, which extends the rod on exhaust.
The -S denotes a built-in piston magnet for position sensing, compatible with reed or electronic solid-state switches. The -B indicates a male M18x1.5 piston rod end thread, allowing direct mechanical coupling to your tooling.
