About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X35
The AirTAC B01-SDA40X35 is a double-acting, single-rod compact air cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the standard SDA40X35, meaning it is mechanically identical to the base model while grouping specific customer builds into a dedicated line. It delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa.
The short riveted body significantly reduces axial mounting depth compared to round-body units, saving valuable machine footprint. It features a hard-anodized 40 mm bore, a 16 mm piston rod, and PT1/8 ports. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, so operators should slow the approach or add external shock absorbers for high-energy loads. This SKU lacks a piston magnet and cannot host sensing switches.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X35 Is Used
CNC Fixture Clamping
Secures aluminum engine blocks during CNC machining, utilizing the 628.3 N extend force to hold parts firmly against cutting vibrations.
Carton Flap Folding
Drives mechanical arms to fold corrugated box flaps at speeds up to 500 mm/s before the sealing head applies tape.
Bottle Diverting Gate
Actuates a routing gate on a beverage filling line to divert glass bottles into downstream labeling stations.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X35 the Right Cylinder?
When sizing this unit, evaluate your neighbours: stepping down to the SDA32 yields 402.1 N push at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N. For this 40 mm bore, a safe working load is roughly 377 N (about 60% of the 628.3 N figure), translating to a vertical lift capacity of approximately 32 kg with a 2:1 safety margin. Confirm your ordering essentials: 40 mm bore, 35 mm stroke, PT1/8 port, female M8x1.25 rod thread, and no magnet. Note that a plain cylinder drifts when air is lost or the valve is centred; the fixed bumper only decelerates near stroke end and does not function as a lock. Use an external rod lock or pilot-operated check valve if the application must hold a load without live pressure.
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 B01-SDA Dedicated Cylinder B01-SDA40X35 FAQ
This double-acting cylinder generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum push is 128 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
The B01- prefix designates an application-dedicated (customer-specified) variant of the SDA40X35, sharing identical physical specs and sizing. Instead of an adjustable air cushion, it uses a fixed NBR bumper at each end to decelerate the stroke. For high kinetic energy loads, you should slow the approach speed or install an external shock absorber.
