The AirTAC SDA80X140SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 140mm 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 SDA80X140SB is a double-acting, single-rod compact cylinder engineered to deliver a substantial 2513.3 N of push 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. This specific configuration includes a built-in piston magnet for position sensing and a male M22x1.5 threaded rod end.
Because the 140 mm stroke exceeds the 130 mm maximum standard stroke for this 80 mm bore, this unit is classified as non-standard and produced as a made-to-order item. The bore is hard-anodized for longevity, and the piston relies on a fixed NBR bumper at each end to decelerate the stroke. Operating speeds span 30-500 mm/s, and the body features integrated grooves that accept AirTAC reed or electronic switches when paired with the internal magnet.

Provides the 2513.3 N push force required to knock heavy stamped metal panels out of progressive dies, utilizing the male M22x1.5 rod for secure tooling attachment.
Raises lowerator forks in packaging lines; the 140 mm stroke transfers goods between conveyors while the compact riveted body minimizes vertical machinery height.
Parts large plastic molds on heavy-duty injection molding machines, where the fixed NBR bumper absorbs the end-stop impact during high-speed 30-500 mm/s extraction cycles.
When sizing this model, compare its 2513.3 N push at 0.5 MPa against adjacent bores: stepping down to the SDA63 yields 1558.6 N, while stepping up to the SDA100 provides 3927 N. Keep in mind that a standard compact cylinder drifts when 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. If your application must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve.
To finalize your order, confirm these essentials: 80 mm bore, 140 mm non-standard stroke, PT3/8 port, built-in magnet (S option), and the male M22x1.5 piston rod thread (B option). Because this is a made-to-order stroke, verify lead times with our team during your RFQ.
Quick checklist
This double-acting single-rod cylinder generates a push force of 2513.3 N and a pull force of 2267.8 N at 0.5 MPa. At 0.7 MPa, the push increases to 3518.6 N. The theoretical maximum push force is 513 kgf at the 1.0 MPa pressure limit.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; this is not an adjustable air cushion, so external shock absorbers are recommended for high-energy cycles. The 'S' option indicates a built-in piston magnet designed to trigger AirTAC reed or electronic switches housed in the body grooves.
