The AirTAC AirTAC SDA80X25BH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 25mm 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 SDA80X25BH is a double-acting, single-rod compact cylinder engineered for high-force actuation within a minimal axial footprint. Utilizing a short riveted body assembly, it significantly reduces mounting depth compared to conventional round-body units, yielding a robust 2513.3 N push force at 0.5 MPa. The FKM (fluororubber) -H seal option equips this unit for elevated temperature or oil-heavy environments, while the 25 mm stroke operates across a 30-500 mm/s speed range.
This specific SKU includes a male M22x1.5 threaded piston rod end (-B) for secure mechanical load coupling, paired with a 25 mm rod diameter to resist deflection. End-of-stroke deceleration relies on fixed NBR bumpers rather than adjustable air cushions, meaning high-energy cycles may require external shock absorption. Because this configuration lacks the -S magnet option, it cannot host reed or electronic switches; position sensing requires a different variant.

Short 25 mm stroke provides the high clamping force needed to secure injection mold halves during surface treatment processes.
Male M22x1.5 rod end drives finished forged components out of a hydraulic press bed, utilizing FKM seals to survive ambient oil exposure.
Riveted compact body lifts heavy sheet metal blanks into stamping dies, saving axial machine space while delivering 2513.3 N of extend force.
When sizing this 80 mm bore model, stepping down to the SDA63 yields 1558.6 N push at 0.5 MPa, whereas stepping up to the SDA100 provides 3927 N at the same pressure. Based on the 2513.3 N output, the computed safe working load is approximately 1508 N (60% capacity), translating to a vertical lift capability of about 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80 mm bore, 25 mm stroke, PT3/8 porting, male M22x1.5 rod thread, and FKM seal composition. Note that a standard cylinder drifts when air pressure is lost; holding a suspended load requires an external rod lock or pilot-operated check valve.
Quick checklist
This 80 mm bore double-acting cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, increasing to 3518.6 N push at 0.7 MPa. The theoretical maximum push is 513 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa with a speed range of 30-500 mm/s.
It uses fixed NBR bumpers to decelerate the piston near stroke end, which is not an adjustable air cushion. For high-energy cycles, add an external shock absorber. Additionally, it cannot hold a load if air pressure drops; an external rod lock or pilot-operated check valve is required for fail-safe vertical holding.
