About the Airtac SDA Ultra Thin Cylinder SDA40X30-B
The AirTAC SDA40X30-B is a double-acting, single-rod compact cylinder engineered to deliver a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth compared to conventional round-body units, making it highly effective for machinery where space savings are critical. The unit operates at speeds between 30-500 mm/s.
This specific SKU is configured with a male M14x1.5 piston rod thread (denoted by the -B option) for secure mechanical coupling to your load, alongside a 16 mm rod diameter and PT1/8 porting. The bore interior is hard-anodized for longevity, while fixed NBR bumpers absorb end-stop impact. Note that this configuration lacks a piston magnet, so it cannot host magnetic switches without the -S option.

Where the Airtac SDA Ultra Thin Cylinder SDA40X30-B Is Used
Injection Mold Ejection
Drives the ejection plate inside a plastics molding cell, utilizing the male M14x1.5 rod end to thread directly into the ejector assembly for reliable part release.
Carton Flap Folding
Deploys a 30 mm stroke to tuck corrugated carton flaps on a continuous packaging line, where the compact riveted body minimizes frame interference.
Pallet Diverter Gate
Actuates a routing gate to redirect heavy pallets, applying 628.3 N of push force at 0.5 MPa to overcome the lateral friction of the conveying surface.
Is the Airtac SDA Ultra Thin Cylinder SDA40X30-B the Right Cylinder?
When sizing this actuator, evaluate your force margins both ways: stepping down to the SDA32 yields 402.1 N of push force at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N. If your sequence requires the load to remain stationary upon air loss or valve centering, be aware the piston will drift; the fixed bumper only decelerates the stroke end and acts neither as a lock nor a brake. You must integrate an external rod lock or pilot-operated check valve for position holding.
To finalize your order, confirm these essentials: 40 mm bore, 30 mm stroke, PT1/8 air port, male M14x1.5 rod thread, and no sensor magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDA Ultra Thin Cylinder SDA40X30-B FAQ
This double-acting cylinder generates 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. At 0.7 MPa, the push increases to 879.6 N. The theoretical maximum push is 128 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, handles temperatures from -20 to +70 C, and runs at speeds of 30-500 mm/s.
No. It relies on fixed NBR bumpers at each end to decelerate the stroke, which cannot be field-adjusted; for high-energy cycles, slow the approach or add an external shock absorber. Additionally, this SKU lacks the -S magnet, meaning it cannot support reed or electronic switches without changing to the -S variant.
