The AirTAC AirTAC SDA40X5H Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 5mm 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 SDA40X5H is a double-acting single-rod compact cylinder engineered for minimal axial footprint. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, it achieves a much shorter overall length than traditional round-body units, making it ideal for machinery where mounting depth is restricted. This specific SKU features a fluororubber (FKM) seal for heightened oil and thermal resistance.
At 40 mm bore, it generates 628.3 N of push force at 0.5 MPa. The 16 mm piston rod utilizes an M8x1.25 female thread, and the body incorporates a fixed NBR bumper at each end to decelerate the stroke. Because this configuration lacks the -S magnet option, it cannot support magnetic reed or electronic switches.

Secures printed circuit boards during routing operations. The 5 mm stroke provides rapid, short-throw holding with 628.3 N of force, while the FKM seal withstands localized heat from cutting debris.
Drives the sealing jaw on vertical form-fill-seal equipment. The ultra-short 5 mm movement ensures rapid cycling, and the compact riveted body conserves valuable space within the packaging head.
Ejects small molded components from a press bed. The fixed NBR bumper absorbs the impact of the 16 mm rod at the end of travel, preventing shock from transferring to the machine frame.
When sizing this unit, consider stepping down to the SDA32, which yields 402.1 N of push at 0.5 MPa, or moving up to the SDA50 for 981.7 N. For this 40 mm bore, the safe working load is approximately 377 N (about 60% of the 628.3 N capacity), translating to a vertical lift capability of roughly 32 kg with a 2:1 safety margin. To finalize your order, confirm the 5 mm stroke, PT1/8 port, female rod thread, and FKM seal. Note that a plain cylinder drifts if air pressure is lost; adding an external rod lock or pilot-operated check valve is necessary to hold a load securely.
Quick checklist
This 40 mm bore double-acting cylinder provides 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 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU lacks the -S piston magnet, meaning it cannot trigger reed or electronic switches. Additionally, it relies on a fixed NBR bumper to decelerate at stroke ends rather than an adjustable air cushion, so external shock absorbers may be needed for high-speed approaches.
