Airtac B01-SDA Dedicated Cylinder B01-SDA20X20
The AirTAC Airtac B01-SDA Dedicated Cylinder B01-SDA20X20 is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 20mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.

About the Airtac B01-SDA Dedicated Cylinder B01-SDA20X20
The AirTAC B01-SDA20X20 is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the standard SDA20X20, meaning it is mechanically identical to the base model. It delivers 157.1 N of push force and 131.9 N of pull force at 0.5 MPa, operating within a 30-500 mm/s speed range.
Its short riveted body significantly reduces axial mounting depth where a round-body unit will not fit. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. This specific SKU lacks a piston magnet and cannot accept magnetic switches, while the 8 mm rod uses an M4x0.7 female thread to drive the load.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA20X20 Is Used
PCB Depaneling Router
Actuates the cutting head feed on an automated PCB depaneling machine, utilizing the short 20 mm stroke and compact body to minimize Z-axis height.
Blister Pack Sealing
Provides the 157.1 N push force required to close a small heated platen for sealing pharmaceutical blister packs without over-stressing the card material.
Lab Dispense Valve
Drives a precision pinch valve for reagent dispensing, where the fixed NBR bumper sufficiently decelerates the low-mass load at cycle completion.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA20X20 the Right Cylinder?
When sizing this 20 mm bore, stepping down to the SDA16 yields 100.5 N of push force at 0.5 MPa, whereas stepping up to the SDA25 provides 245.4 N. For this 157.1 N @0.5 MPa rating, a safe working load is approximately 94 N (about 60 percent of capacity), translating to a vertical lift of roughly 8 kg with a 2:1 safety margin. Confirm your ordering essentials: 20 mm bore, 20 mm stroke, M5x0.8 port, female rod thread, and no magnet. Because a plain compact cylinder drifts when air is lost or a valve centers, holding a suspended load requires an external rod lock or 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-SDA20X20 FAQ
This 20 mm bore double-acting cylinder provides 157.1 N push and 131.9 N pull at 0.5 MPa. At 0.7 MPa, push is 219.9 N and pull is 184.7 N. The theoretical maximum push force is 32 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
The B01- prefix indicates an application-dedicated (customer-specified) variant of the SDA20X20, with no mechanical or dimensional changes to the base cylinder. This specific SKU does not have a piston magnet, so it cannot use reed or electronic switches. Sensing requires the -S magnet option.
