The AirTAC AirTAC SDA50X35SB 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 SDA50X35SB 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 conventional round-body units, making it highly effective for machinery where space footprint is critical. The unit includes a built-in piston magnet for position sensing.
This specific configuration features a 50 mm bore, a 35 mm stroke, and a PT1/4 air port. Because it carries the B option code, the 20 mm piston rod terminates in a male M18x1.5 thread for direct load coupling. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add external shock absorbers for high-energy loads.

Pushes medium-weight cartons off a main sorting line using 981.7 N of extend force, fitting neatly into tight transfer station gaps.
Secures aluminum engine blocks during machining via the male M18x1.5 rod end, providing rigid holding without excessive overhang.
Actuates a short 35 mm lift mechanism for lower-tier pallet entry, relying on the built-in magnet to confirm gate position.
When sizing this unit, evaluate your force requirements 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. The SDA50X35SB provides a safe working load of roughly 589 N (about 60% of its 981.7 N capacity) and can vertically lift approximately 50 kg with a 2:1 safety margin. To finalize your order, confirm the 50 mm bore, 35 mm stroke, PT1/4 port, male M18x1.5 rod thread, and the required magnetic sensor. Note that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near stroke end and does not function as a locking brake; use an external rod lock or pilot-operated check valve if the load must be held.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder generates 981.7 N of push force and 824.7 N of pull force. At 0.7 MPa, push increases to 1374.4 N. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed range of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-speed cycles, adding an external shock absorber is advised. The built-in magnet allows tracking by AirTAC reed or electronic switches mounted in the body grooves.
