The AirTAC AirTAC SDA50X130B Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 130mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA50X130B is a double-acting, single-rod compact cylinder engineered to deliver 981.7 N of push force at 0.5 MPa. This specific configuration includes a 130 mm stroke, which qualifies as a made-to-order non-standard length for this 50 mm bore, extending past the 120 mm standard limit to provide extended travel within a minimal footprint. The riveted body assembly significantly reduces axial mounting depth compared to conventional round-body units, making it highly effective for machinery where space savings are critical.
This unit features a male M18x1.5 threaded piston rod (denoted by the B option) for secure mechanical load coupling, alongside a 20 mm rod diameter and PT1/4 air port. Deceleration at the stroke extremes is handled by a fixed NBR bumper; because this is not an adjustable air cushion, operators should reduce approach speed or mount an external shock absorber for high-energy loads. Note that this SKU lacks a piston magnet, so position sensing is not supported without the -S option.

Actuates routing gates on packaging conveyor lines, utilizing the 130 mm stroke and 981.7 N push force to redirect heavy cardboard cartons efficiently.
Raises small auxiliary tooling platforms in assembly cells, providing a stable vertical lift of approximately 50 kg with a 2:1 safety margin at 0.5 MPa.
Adjusts the position of heavy film rolls on shrink-wrapping machinery, where the male M18x1.5 rod end securely mounts the tensioning bracket assembly.
When sizing this actuator, consider stepping down to the SDA40, which yields 628.3 N of push at 0.5 MPa, or moving up to the SDA63, which provides 1558.6 N at the same pressure. For the current 50 mm bore, the safe working load is approximately 589 N (about 60% of the 981.7 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; maintaining vertical loads requires an external rod lock or a pilot-operated check valve. To order, confirm the 50 mm bore, 130 mm stroke, PT1/4 port, male M18x1.5 rod thread, and the absence of a sensor magnet.
Quick checklist
At 0.5 MPa, the push force is 981.7 N and the pull force is 824.7 N. At 0.7 MPa, the push force is 1374.4 N. The theoretical maximum push force is 200 kgf at the maximum operating pressure of 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. You would need to specify the -S option (SDA50X130BS) to enable magnetic sensing in the body grooves.
