The AirTAC SDA50X35H 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 SDA50X35H is a double-acting, single-rod compact cylinder engineered with a 50 mm bore and 35 mm stroke. Its riveted assembly significantly reduces axial mounting depth compared to round-body units, saving valuable machine footprint. Equipped with a fluororubber (FKM) seal, this version provides enhanced thermal and oil resistance for demanding environments. It generates 981.7 N of push force and 824.7 N of pull force at 0.5 MPa.
This model features a 20 mm piston rod and PT1/4 air ports. Instead of an adjustable air cushion, it relies on a fixed NBR bumper at each end to decelerate the stroke. Because this SKU lacks the -S magnet option, it cannot support magnetic reed or electronic switches. The compact body is designed for short strokes, with a maximum standard stroke of 130 mm for this bore size.

Secures heavy aluminum castings inside CNC machining centers. The FKM seal withstands cutting fluid spray while providing 981.7 N of clamping force at 0.5 MPa.
Indexes empty wooden pallets into an automated packaging line. The short riveted body fits neatly within tight conveyor framework constraints.
Actuates a heavy diverter gate on a gravity conveyor. The 35 mm stroke provides precise diversion without excessive overtravel.
When sizing this actuator, compare it against adjacent bores: 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. To order, confirm the 50 mm bore, 35 mm stroke, PT1/4 port, female rod thread (M10x1.5), and the FKM seal. Note that a plain SDA cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; the fixed bumper only decelerates near the stroke end and does not function as a lock or brake. For position holding, an external rod lock or pilot-operated check valve is required.
Quick checklist
This 50 mm bore 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 force is 200 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 piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option for sensing capabilities. Additionally, it uses a fixed NBR bumper rather than an adjustable air cushion to decelerate the stroke end.
