The AirTAC SDA50X90B Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 90mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA50X90B is a double-acting, single-rod compact cylinder engineered to deliver 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. Its riveted body assembly significantly reduces axial mounting depth compared to traditional round-body units, providing a highly space-efficient footprint for tight machine builds. The 50 mm bore features a hard-anodized inner wall and operates on filtered air at 30-500 mm/s.
This specific configuration includes the B option, providing a male M18x1.5 threaded piston rod for secure mechanical load coupling. End-of-stroke deceleration is handled by fixed NBR bumpers rather than adjustable cushions, meaning high-energy cycles may require external shock absorbers. Note that this SKU lacks the S magnet option, so position sensing via reed or electronic switches is not supported without modifying the build.

Pushes medium-weight cartons off a sorting line using 981.7 N of thrust, with the 90 mm stroke clearing the belt edge efficiently.
Ejects formed plastic parts from a press bed where the short riveted body minimizes axial interference behind the moving platen.
Acts as a pneumatic stop for incoming pallets, relying on the 20 mm rod and male M18x1.5 thread to absorb repeated mechanical side impacts.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N. If your mechanism must maintain vertical position during air loss or valve centering, be aware the piston will drift; the fixed bumper only decelerates near stroke end and acts as neither a lock nor a brake. An external rod lock or pilot-operated check valve is required for holding.
Confirm these ordering essentials before finalizing your RFQ: 50 mm bore, 90 mm stroke, PT1/4 porting, female rod-end thread default overridden by the male M18x1.5 B option, and no sensor magnet.
Quick checklist
This double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, increasing to 1374.4 N push and 1154.5 N pull at 0.7 MPa. The theoretical maximum push force is 200 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No adjustable air cushion exists; it uses fixed NBR bumpers to decelerate at stroke end, so high-speed applications need external shock absorption. Additionally, this SKU lacks the S magnet, meaning reed or electronic switches cannot be used unless a magnet-equipped variant is ordered.
