The AirTAC AirTAC SDA20X60B Compact Cylinder | 20mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 60mm 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.
The AirTAC SDA20X60B is a double-acting, single-rod compact cylinder engineered to deliver 157.1 N of push force and 131.9 N of pull force at 0.5 MPa. Its riveted body design integrates the barrel, rear cover, piston, and rod into a highly abbreviated axial package, saving valuable mounting depth in tight machinery footprints where longer round-body units cannot fit.
This specific configuration includes a male M6x1.0 piston rod thread for secure mechanical coupling to your load. The 8 mm rod operates within a hard-anodized bore, and deceleration is handled by a fixed NBR bumper at each end. Note that this SKU lacks a piston magnet, so it cannot host magnetic switches.

Thread: PT standard. Related SDA-family variants: SSA (single-acting push), STA (single-acting pull), SDAD (double rod), SDAJ (adjustable stroke), SDAT (duplex), SDAW (duplex-end).
Provides the 157.1 N extend force needed to clamp PCB panels during routing operations, utilizing the male M6 thread for a custom tooling tip.
Actuates a short diverter arm on a packaging conveyor, where the 60 mm stroke and space-saving riveted body fit neatly between belt supports.
Moves a volumetric dispensing head into position over reagent bottles, taking advantage of the 30-500 mm/s speed range for rapid cycling.
When sizing this unit, evaluate your neighbors: the SDA16 provides 100.5 N of push at 0.5 MPa for lighter duties, while the SDA25 steps up to 245.4 N for heavier cycles. Based on the 157.1 N output, the safe working load is approximately 94 N (around 60% capacity), translating to a vertical lift capability of roughly 8 kg with a 2:1 safety margin. To order, confirm the 20 mm bore, 60 mm stroke, M5x0.8 port, male M6x1.0 rod thread, and no magnet. If the application must hold a load without live pressure, the piston will drift; an external rod lock or pilot-operated check valve is required.
Quick checklist
At 0.5 MPa, this 20 mm bore cylinder outputs 157.1 N push and 131.9 N pull. At 0.7 MPa, push increases to 219.9 N. The theoretical maximum push force is 32 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
There is no adjustable air cushion; the unit relies on a fixed NBR bumper at each end to decelerate the stroke. Additionally, this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches. You would need the -S variant for sensing capabilities.
