The AirTAC AirTAC SDA80X90SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 90mm 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 SDA80X90SB is a double-acting single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. By utilizing a short riveted body that permanently joins the barrel, rear cover, piston, and rod, this unit drastically reduces axial mounting depth compared to conventional round-body actuators. This space-saving footprint is critical when integrating heavy push capability into tight machine envelopes. The 80 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable service.
This specific configuration includes the S option for a built-in piston magnet, allowing seamless integration with AirTAC magnetic reed or electronic switches via the grooves around the body. The B option equips the 25 mm piston rod with a male M22x1.5 thread for robust load coupling. End-stopping is handled by a fixed NBR bumper that decelerates the piston near stroke end; because this is not an adjustable air cushion, high-energy cycles may require an external shock absorber or a slowed approach.

Drives heavy mold ejection plates in plastic injection machinery where the 2513.3 N push force and 90 mm stroke efficiently eject dense parts, while the compact riveted body minimizes rear-frame intrusion.
Indexes thick gauge metal stock into mechanical stamping presses, utilizing the male M22x1.5 rod end for secure tooling attachment and the 80 mm bore power to push heavy billets.
Actuates diverter lift gates on high-throughput packaging palletizers, where the built-in S magnet triggers reed or electronic switches to confirm gate position for the 128 kg safe lifting margin.
When sizing this 80 mm bore actuator, compare its 2513.3 N push at 0.5 MPa against adjacent options. Stepping down, the SDA63 provides 1558.6 N, while stepping up to the SDA100 yields 3927 N at the same pressure. For this SDA80X90SB configuration, the computed safe working load is approximately 1508 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80 mm bore, 90 mm stroke, PT3/8 port, built-in magnet (S), and male M22x1.5 rod thread (B). Remember that a plain compact cylinder does not hold its load if air pressure is lost or the valve is centered—the piston will drift, as the fixed bumper only decelerates near the stroke end and acts as neither a lock nor a brake. For suspended or vertical loads, an external rod lock or pilot-operated check valve is required.
Quick checklist
This double-acting 80 mm bore 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 is 513 kgf at the 1.0 MPa operating pressure limit. It operates at speeds between 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. Furthermore, the cylinder does not hold its load on air loss; the piston drifts when pressure is removed. To maintain vertical position without live pressure, you must install an external rod lock or pilot-operated check valve.
