The AirTAC AirTAC SDA40X110B 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 SDA40X110B 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 body design significantly reduces axial mounting depth compared to traditional round-body units, making it highly effective for machinery where space savings are critical. This specific configuration includes a male M14x1.5 piston rod thread for robust load coupling.
This model features a 16 mm piston rod and PT1/8 air ports. It relies on a fixed NBR bumper at each end to decelerate the stroke end rather than an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot accept magnetic position switches; adding the -S variant enables reed or electronic sensing.

Pushes cartons onto auxiliary sorting lanes within high-speed logistics hubs, utilizing the 628.3 N extend force to reliably overcome side friction.
Actuates the tool-release mechanism on automated milling centers, where the male M14x1.5 rod end securely threads into the toolholder interface.
Presses warped cardboard sheets flat against a fixture before stretch wrapping, taking advantage of the 110 mm stroke to accommodate varying stack heights.
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 at the same pressure. For your current 628.3 N output, a safe working load is approximately 377 N (about 60% of capacity), which equates to a vertical lift capability of roughly 32 kg with a 2:1 safety margin. Be aware that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the valve is centered; maintaining vertical loads requires an external rod lock or a pilot-operated check valve. To order, confirm the 40 mm bore, 110 mm stroke, PT1/8 port, male M14x1.5 rod thread, and no magnet.
Quick checklist
This 40 mm bore cylinder generates a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, the push increases to 879.6 N. The theoretical maximum push is 128 kgf at the 1.0 MPa operating pressure limit.
No, this actuator uses a fixed NBR bumper at each end to absorb impact energy, which is not field-adjustable. If your cycle operates at high speeds or moves large masses, you should slow the approach speed or install an external shock absorber.
