The AirTAC AirTAC SDA80X30BH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 30mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA80X30BH is a double-acting compact cylinder engineered to deliver a robust 2513.3 N push force at 0.5 MPa. Its riveted assembly integrates the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth where a conventional round-body actuator would be too bulky. Driven by a 25 mm piston rod, this unit utilizes a PT3/8 port to efficiently manage high airflow.
This specific SKU includes the -B male-thread piston rod end (M22x1.5) for secure mechanical load coupling, alongside the -H fluororubber (FKM) seal option for enhanced thermal and oil resistance. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Because this configuration lacks the -S magnet, it cannot support magnetic position sensing without changing the piston assembly.

Drives heavy mold ejection plates in plastic injection machinery where the short riveted body minimizes press footprint and the FKM seals withstand residual heat.
Pushes thick gauge metal blanks into stamping presses, utilizing the 2513.3 N extend force and the rigid male M22x1.5 rod thread for high-impact alignment.
Raises and lowers heavy palletizing forks, safely handling loads near the 128.1 kg vertical lift limit when paired with external guidance to prevent side loading.
When sizing this actuator, evaluate your neighbors: stepping down to the SDA63 yields 1558.6 N push at 0.5 MPa, while the larger SDA100 provides 3927 N. The 80 mm bore here offers a computed safe working load of roughly 1508 N (about 60% of its 0.5 MPa capacity) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the valve is centered; maintaining vertical loads requires an external rod lock or a pilot-operated check valve. To order, confirm the 80 mm bore, 30 mm stroke, PT3/8 port, male M22x1.5 rod thread, and FKM seal configuration.
Quick checklist
This double-acting cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa. At 0.7 MPa, push increases to 3518.6 N. The theoretical maximum push force is 513 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No adjustable air cushion is present; it relies on a fixed NBR bumper to decelerate the stroke end, so external shock absorbers are recommended for high-speed approaches. Additionally, this SKU lacks the -S magnet, meaning it cannot support reed or electronic switches without a piston change.
