The AirTAC SDA20X130SB Compact Cylinder | 20mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 130mm 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 SDA20X130SB is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly significantly reduces axial mounting depth compared to round-body units, yielding a theoretical push of 157.1 N at 0.5 MPa. This specific configuration includes a built-in piston magnet for position sensing alongside a male M6x1.0 piston rod thread.
Because the 130 mm stroke exceeds the 100 mm maximum standard length for this 20 mm bore, it is manufactured as a non-standard, made-to-order item. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorption.

Pushes a tooling pin to fixture populated circuit boards during the routing and cutting process, utilizing the 157.1 N extend force within a compact electronics assembly cell.
Extends a lightweight paddle over 130 mm to deflect small parcels on a logistics belt, where the short body depth prevents interference with adjacent conveyor supports.
Drives a male M6x1.0 tipped probe down into test tube racks for fluid aspiration, relying on the magnetic piston for precise reed or electronic switch positioning.
When sizing this actuator, consider stepping down to the SDA16 which provides 100.5 N of push at 0.5 MPa, or moving up to the SDA25 which yields 245.4 N. Confirm your ordering essentials: 20 mm bore, 130 mm stroke, M5x0.8 port, male M6x1.0 rod, and the -S magnet.
Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered. The fixed NBR bumper only slows the piston near the stroke end and does not function as a locking brake. If your application must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 20 mm bore cylinder generates a push of 157.1 N and a pull of 131.9 N at 0.5 MPa. At 0.7 MPa, the push is 219.9 N. The theoretical maximum push is 32 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
The 130 mm stroke is non-standard and made-to-order, exceeding the 100 mm standard maximum for this bore. It uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. For high-speed or high-energy cycles, you should slow the approach or add an external shock absorber.
