The AirTAC AirTAC SDA50X90 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 SDA50X90 is a double-acting single-rod compact cylinder delivering 981.7 N of push force at 0.5 MPa. Its riveted assembly keeps the total axial length exceptionally short, saving valuable mounting depth where a conventional round-body unit would protrude too far into the machine frame. The hard-anodized bore and two-way piston seal ensure durable service.
This specific configuration features a 50 mm bore, a 90 mm stroke, and a PT1/4 port. It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches for position sensing.

Actuates routing flaps on high-speed logistics conveyors, utilizing the 981.7 N thrust to push heavy cartons into secondary sorting chutes without extending too deep into the conveyor frame.
Holds stretch-wrap film rolls tight against pallet loads during the wrapping cycle, using the 90 mm stroke to accommodate varying pallet heights while maintaining consistent tension.
Drives secondary ejection pins to free molded plastic parts from tooling, where the short body length prevents interference with the mold clamping mechanism.
When sizing this unit, 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, allowing you to scale thrust precisely to your load. Based on the 981.7 N figure at 0.5 MPa, the safe working load is approximately 589 N (60 percent capacity), translating to a vertical lift capability of about 50 kg with a 2:1 safety margin.
Remember that a standard compact cylinder drifts when air pressure is lost or the directional valve is centered, as the fixed bumper only absorbs end-of-stroke impacts rather than locking the rod. To secure a suspended load, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 50 mm bore, 90 mm stroke, PT1/4 port, female M10x1.5 rod thread, and no sensor magnet.
Quick checklist
This double-acting cylinder provides 981.7 N push and 824.7 N pull at 0.5 MPa, and 1374.4 N push at 0.7 MPa. The theoretical maximum push is 200 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, runs at 30-500 mm/s, and functions in temperatures from -20 to +70 C.
No, this SKU has no piston magnet (-S option omitted), so it cannot support reed or electronic switches. Additionally, it uses a fixed NBR bumper at the stroke ends for deceleration rather than a field-adjustable air cushion; for high kinetic energy loads, slow the approach or add an external shock absorber.
