The AirTAC AirTAC SDA50X35SN Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 35mm 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 SDA50X35SN 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 assembly merges the barrel, rear cover, piston, and rod into an ultra-short profile, drastically reducing axial mounting depth compared to traditional round-body units. The 50 mm bore features a hard-anodized inner wall and a 20 mm piston rod that mates via a female M10x1.5 thread.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, absorbing impact energy within the compact envelope. Operating efficiently between 30 and 500 mm/s, it handles a safe working load of roughly 589 N, which translates to a vertical lift capacity of about 50 kg with a 2:1 safety margin.

Pushes medium-weight cartons at 981.7 N onto secondary packaging lines, utilizing the 35 mm stroke to clear the main conveyor belt rapidly.
Ejects molded plastic parts from tooling cavities, where the short riveted body minimizes machine footprint and the 20 mm rod resists buckling.
Raises light aluminum pallets vertically, safely handling approximately 50 kg loads with a 2:1 safety margin before downstream processing.
When sizing this actuator, evaluate your force requirements carefully. If you need less thrust, the smaller SDA40 bore provides 628.3 N of push at 0.5 MPa; stepping up to the SDA63 yields 1558.6 N for heavier payloads. To finalize this exact model, confirm the 50 mm bore, 35 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the required magnetic sensor option.
Keep in mind that a standard double-acting cylinder like this will not hold a load if air pressure drops or the directional valve centers. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its limits without acting as a mechanical brake. For vertical loads requiring fail-safe holding, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This 50 mm bore 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 an operating pressure range of 0.15-1.0 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a locking brake. The included -S piston magnet allows you to track position using AirTAC reed or electronic switches mounted in the body grooves.
