The AirTAC AirTAC SDA40X110 Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 110mm 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 SDA40X110 is a double-acting, single-rod compact cylinder engineered to deliver a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. Its riveted assembly securely joins the barrel, rear cover, piston, and rod, yielding an exceptionally short axial footprint where a conventional round-body unit would not fit. The 40 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable low-friction operation.
This specific configuration provides a 110 mm stroke and utilizes a 16 mm piston rod with a female M8x1.25 thread end. End-stop energy is managed strictly by a fixed NBR bumper, which decelerates the piston near the stroke limits rather than acting as a lock. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Actuates a routing flap on a logistics sorting line, using the 110 mm stroke to shift parcels between adjacent conveyor belts with 628.3 N of extend force.
Drives a secondary ejector pin plate in a plastics molding cell, where the short riveted body minimizes axial interference behind the stationary platen.
Pushes side flaps of corrugated cartons prior to tape sealing in a packaging machine, benefiting from the 30-500 mm/s speed range to match line throughput.
When sizing this actuator, stepping down to the SDA32 yields 402.1 N of push force at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N, allowing you to tune the capacity precisely to your load. For the SDA40X110, a safe working load is approximately 377 N (about 60% of the 628.3 N figure), which translates to a vertical lift capacity of roughly 32 kg when applying a 2:1 safety margin. To finalize your order, confirm the 40 mm bore, 110 mm stroke, PT1/8 port, female rod thread, and the absence of a sensor magnet.
If your mechanism must maintain its position during a compressed air loss or when the control valve is centered, this cylinder will drift. The fixed NBR bumper only decelerates the piston near the stroke end and does not function as a brake. You will need to integrate an external rod lock or a pilot-operated check valve to hold a suspended load securely.
Quick checklist
At 0.5 MPa, the push force is 628.3 N and the pull force is 527.8 N. At 0.7 MPa, the push force is 879.6 N and the pull force is 738.9 N. The theoretical maximum push force is 128 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No, end-of-stroke energy is absorbed only by a fixed NBR bumper, which is not an adjustable air cushion. For high kinetic energy loads, you should add an external shock absorber. Additionally, this specific SKU lacks the -S piston magnet, so it cannot host AirTAC reed or electronic switches without changing to an -S variant.
