The AirTAC AirTAC SDA80X150SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 150mm 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 SDA80X150SB is a double-acting, single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Because the 150 mm stroke exceeds the 130 mm standard limit for this 80 mm bore, this specific unit is treated as a non-standard, made-to-order configuration. The short riveted body design significantly reduces axial mounting depth compared to conventional round-body units, providing a highly space-efficient footprint for heavy-duty machinery.
This model includes a built-in piston magnet (-S) for direct compatibility with AirTAC reed or electronic switches along the body grooves. It is also configured with a male-thread piston rod (-B) measuring M22x1.5, ensuring a robust mechanical coupling to your load. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should incorporate external shock absorbers if cycling at the maximum 500 mm/s speed.

Drives heavy mold ejector pins in plastic injection machinery where the short riveted body minimizes axial footprint behind the stationary platen.
Provides the 2513.3 N push force required to press and bend thick sheet metal blanks in automated stamping lines.
Lifts loaded pallets vertically; the male M22x1.5 rod end secures heavy lifting forks while operating within a 0.15-1.0 MPa pressure range.
When sizing this 80 mm bore actuator, consider stepping down to the SDA63, which provides 1558.6 N of push force at 0.5 MPa, or stepping up to the SDA100, which yields 3927 N at the same pressure. For the SDA80X150SB, the computed safe working load is approximately 1508 N (about 60% of the 2513.3 N figure), allowing a vertical lift of roughly 128.1 kg with a 2:1 safety margin. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near the stroke end and does not function as a locking brake. If your application requires strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
To finalize your order, confirm these exact specifications: an 80 mm bore, a 150 mm non-standard stroke, PT3/8 air ports, the built-in magnet for sensing, and the male M22x1.5 piston rod thread.
Quick checklist
This 80 mm bore double-acting cylinder provides 2513.3 N push and 2267.8 N pull at 0.5 MPa, and 3518.6 N push at 0.7 MPa. The theoretical maximum push force is 513 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
It relies on a fixed NBR bumper to decelerate the piston at each end, which is not a field-adjustable air cushion; for high-speed cycling, add an external shock absorber. Additionally, it does not hold its load on air loss—the piston drifts, so an external rod lock is required for strict position holding.
