Airtac SSA Single-Acting Compact Cylinder SSA63X15B
The AirTAC Airtac SSA Single-Acting Compact Cylinder SSA63X15B is a genuine single-acting COMPACT cylinder (single acting, push type) with a Ø63mm bore and 15mm stroke. Air pushes 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 SSA Single-Acting Compact Cylinder SSA63X15B
The AirTAC SSA63X15B is a compact single-acting push-type cylinder where air extends the rod and an internal spring retracts it. This 63 mm bore unit generates 1382.6 N of net push force at 0.5 MPa, with the return spring counter-force already subtracted from the raw air pressure. Because it relies on a single air line and one solenoid port, plumbing is drastically simplified for short-stroke ejection tasks.
Designed with a short riveted body, this model saves axial mounting depth where a larger profile cylinder cannot fit. It features a 20 mm piston rod, a PT1/4 port, and a male M18x1.5 thread on the rod end. A fixed NBR bumper handles end-of-stroke deceleration, offering reliable shock absorption without adjustable air cushions.
Airtac SSA Single-Acting Compact Cylinder SSA63X15B Technical Specifications
| Model | Airtac SSA Single-Acting Compact Cylinder SSA63X15B |
|---|---|
| Series | SSA compact single-acting cylinder |
| Bore size | Ø63 mm |
| Stroke | 15 mm |
| Acting type | Single acting, push 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 | 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 (Ø63mm, Push)
| Pressure | Push force (net) |
|---|---|
| 0.5 MPa | 1383 N |
| 0.7 MPa | 2006 N |
These are NET output forces — the return-spring force is already deducted. Single-acting push only; the spring performs the opposite stroke. Size with a safety margin.

Where the Airtac SSA Single-Acting Compact Cylinder SSA63X15B Is Used
Heavy-Duty Stamping Ejector
Uses the 1382.6 N net push at 0.5 MPa to positively eject thick metal blanks from a die, with the male M18x1.5 rod threading securely into a heavy tool steel ejector plate.
Automotive Component Pinning
Drives a robust 20 mm rod to press locating pins into dense cast housings on an assembly line, taking advantage of the short riveted body to fit within multi-axis weld fixtures.
Pallet Brake Block Setter
Applies over 2000 N of force at 0.7 MPa to press friction material into steel backing plates, while the single-acting spring return eliminates the need for a dual-pressure valve manifold.
Is the Airtac SSA Single-Acting Compact Cylinder SSA63X15B the Right Cylinder?
When sizing this model, consider the neighboring bores to match your exact output needs. Stepping down, the SSA50 provides 874.7 N of net push at 0.5 MPa, which is significantly less power than this 63 mm bore. If your application requires the full 1382.6 N at 0.5 MPa (or 2006.1 N at 0.7 MPa), this unit is the correct choice. Keep in mind the maximum standard stroke limit of 30 mm for this series.
This specific configuration includes a male M18x1.5 rod thread (denoted by the B option) and lacks a piston magnet, meaning it cannot support reed or electronic switches without the S variant. Operating pressure must be maintained between 0.2 and 1.0 MPa, as a minimum of 0.2 MPa is required to overcome the internal spring. Note that upon air loss, the spring drives the rod back to its retracted rest position; it will not hold a mid-stroke load without external mechanical locking.
Quick checklist
- ✓ Net push 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 SSA Single-Acting Compact Cylinder SSA63X15B FAQ
The SSA63X15B provides a net push force of 1382.6 N at 0.5 MPa and 2006.1 N at 0.7 MPa. These figures already account for the counter-force of the internal return spring, giving you the true usable output for your design calculations.
No, this is a single-acting push cylinder where the internal spring retracts the rod when air is released. It cannot hold a mid-stroke load or lock in place without live pressure. For load holding, you would need a double-acting SDA cylinder paired with an external rod lock.
