The AirTAC AirTAC SDA40X90B Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 90mm 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 SDA40X90B is a double-acting single-rod compact cylinder engineered to deliver 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. Its 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 specific SKU features a male M14x1.5 piston rod thread for robust mechanical coupling to your load.
This model incorporates a hard-anodized bore and relies on a fixed NBR bumper at each end to decelerate the stroke. Because it lacks the -S option, this particular unit has no piston magnet and cannot support magnetic sensing. Operating efficiently between 30-500 mm/s, it handles a safe working load of roughly 377 N, which translates to a vertical lift capacity of about 32 kg with a 2:1 safety margin.

Pushes cartons onto auxiliary sorting lanes within high-speed distribution hubs, utilizing the 628.3 N extend force to overcome side friction.
Ejects formed plastic components from small to medium injection moulding tools where the short riveted body minimizes press footprint.
Folds corrugated cardboard flaps prior to sealing on automated case erecting lines, taking advantage of the 90 mm travel and male M14x1.5 rod.
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 which provides 981.7 N at the same pressure. The 90 mm stroke is well within the 130 mm maximum standard stroke limit for this 40 mm bore. To finalize your order, confirm the PT1/8 port, the male M14x1.5 rod thread (indicated by the B code), and note that this configuration omits the magnet. If your application must hold a load vertically without continuous air pressure, be aware the piston will drift; an external rod lock or pilot-operated check valve is required, as the fixed rubber bumper only slows travel near the end of the stroke and acts as neither a brake nor a locking mechanism.
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, push is 879.6 N and pull is 738.9 N. The theoretical maximum push is 128 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU does not include the -S option, meaning it lacks a piston magnet and cannot trigger AirTAC reed or electronic switches. You would need the -S variant to utilize the sensor grooves around the body for position feedback.
