About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X50
The AirTAC B01-SDA40X50 is a double-acting, single-rod compact air cylinder. The leading "B01-" prefix designates this as an application-dedicated, customer-specified variant of the standard SDA40X50, meaning it is mechanically identical to the base model. It delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa, utilizing a 16 mm piston rod and PT1/8 air port.
Its short riveted body significantly reduces axial mounting depth compared to round-body units, saving valuable machine footprint. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, so high-speed applications should incorporate external shock absorbers. This specific SKU lacks a piston magnet and therefore cannot support magnetic sensing.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X50 Is Used
CNC Fixture Clamping
Secures aluminium engine blocks during CNC machining, utilizing the 628.3 N push force to maintain rigid clamping without overwhelming the fixture geometry.
Carton Flap Folding
Actuates folding mechanisms on corrugated box erecting lines, where the 50 mm stroke and compact riveted body fit neatly within tight conveyor side frames.
Pallet Diverter Gate
Pushes diversion guides to route wooden pallets onto secondary handling tracks, relying on the 16 mm rod to withstand repetitive lateral routing forces.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X50 the Right Cylinder?
When sizing this 40 mm bore unit, verify your force needs against neighbouring options. Stepping down, the SDA32 provides 402.1 N of push at 0.5 MPa; stepping up, the SDA50 yields 981.7 N at the same pressure. For the B01-SDA40X50, the safe working load is approximately 377 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of roughly 32 kg with a 2:1 safety margin.
Confirm your ordering essentials: 40 mm bore, 50 mm stroke, PT1/8 port, female M8x1.25 rod thread, and no magnet. Note that a plain cylinder like this will drift and cannot hold a load if air pressure is lost or the valve is centred—the fixed bumper only decelerates near stroke end, so an external rod lock or pilot-operated check valve is required for position holding.
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-SDA40X50 FAQ
At 0.5 MPa, the push force is 628.3 N and the pull force is 527.8 N. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum push is 128 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a speed of 30-500 mm/s.
The B01- prefix indicates an application-dedicated, customer-specified build of the standard SDA40X50, with no mechanical or dimensional changes to the base cylinder. This specific SKU does not include a piston magnet, so it cannot accept reed or electronic switches; you would need the -S option for sensing capabilities.
