About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X25B
The AirTAC B01-SDA40X25B is a double-acting single-rod compact cylinder engineered for tight axial spaces. The leading B01- prefix denotes an application-dedicated (customer-specified) variant of the standard SDA40X25B, meaning it shares the exact same mechanical architecture and specifications. It delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. The short riveted body integrates the barrel, rear cover, piston, and rod to drastically reduce mounting depth compared to round-body units.
This specific SKU features a male M14x1.5 thread on the 16 mm piston rod for rigid load coupling, and uses a PT1/8 port. The bore is hard-anodized for longevity, and deceleration at the stroke ends relies on a fixed NBR bumper rather than an adjustable air cushion. Because this configuration lacks the S magnet option, it cannot host magnetic position sensors.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X25B Is Used
CNC Fixture Clamping
Secures aluminum housings during machining operations, utilizing the 628.3 N extend force to lock parts firmly against locators in a confined tombstone footprint.
Carton Flap Folding
Drives mechanical arms to tuck corrugated box flaps prior to sealing, where the 25 mm stroke and fixed NBR bumpers provide rapid, repeatable end-stop impact absorption.
Package Diverting Gate
Actuates a routing paddle on a sorting line to push parcels into secondary chutes, taking advantage of the male M14x1.5 rod end for a rigid linkage.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X25B the Right Cylinder?
When sizing this actuator, 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. This 40 mm bore provides a calculated safe working load of roughly 377 N (about 60% of its 628.3 N capacity), making it suitable for lifting approximately 32 kg vertically with a 2:1 safety margin. To finalize your order, confirm the 40 mm bore, 25 mm stroke, PT1/8 port, male M14x1.5 rod thread, and the absence of a sensor magnet.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the motion near the end of the stroke. If your application requires strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
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-SDA40X25B FAQ
At 0.5 MPa, this 40 mm bore double-acting cylinder provides 628.3 N of push force and 527.8 N of pull force. At 0.7 MPa, the push increases to 879.6 N and the pull to 738.9 N. 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 from 30 to 500 mm/s.
The B01- prefix indicates this is an application-dedicated (customer-specified) variant of the SDA40X25B, retaining identical physical specifications. This particular unit lacks a piston magnet, so it cannot support AirTAC reed or electronic switches. Additionally, it relies on a fixed NBR bumper for end-stop deceleration rather than an adjustable air cushion.
