The AirTAC AirTAC SDA40X130BH Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 130mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA40X130BH is a double-acting compact cylinder engineered for tight axial spaces, utilizing a riveted body that significantly reduces mounting depth compared to round-body units. It delivers a robust 628.3 N push force at 0.5 MPa, making it suitable for medium-duty positioning tasks.
This specific configuration includes a 130 mm stroke, a male M14x1.5 piston rod end for secure mechanical coupling, and high-temperature fluororubber (FKM) seals. It relies on a fixed NBR bumper at each end to decelerate the stroke end, which is not an adjustable air cushion, so high-energy cycles may require external shock absorption.

Secures aluminum engine blocks during machining operations, utilizing the 628.3 N extend force and FKM seals to withstand cutting fluid exposure.
Actuates a routing gate on a logistics sorting line, where the 130 mm stroke pushes parcels efficiently without consuming excessive frame width.
Drives a short stroke forming press in a pharmaceutical packaging machine, relying on the fixed NBR bumper to soften the end-of-stroke impact.
When sizing this actuator, evaluate your force margins carefully: stepping down to the SDA32 yields 402.1 N push at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N. For the 628.3 N rating at 0.5 MPa, a safe working load is approximately 377 N (about 60% capacity), translating to a vertical lift capability of roughly 32 kg with a 2:1 safety margin. Note that a plain compact cylinder drifts when air is lost or a valve is centered; the fixed bumper only decelerates near the stroke end and does not function as a lock. To hold a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 40 mm bore, 130 mm stroke, PT1/8 port, male M14x1.5 rod thread, FKM seals, and no sensor magnet.
Quick checklist
This 40 mm bore double-acting cylinder generates 628.3 N push and 527.8 N pull at 0.5 MPa. At 0.7 MPa, it yields 879.6 N push and 738.9 N pull. The theoretical maximum push force is 128 kgf at the 1.0 MPa operating pressure limit.
No, this specific SKU lacks the -S option, meaning it has no piston magnet and cannot trigger AirTAC reed or electronic switches. You would need to select the -S variant to utilize the sensor grooves machined into the cylinder body.
