The AirTAC AirTAC SDA80X90B 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 SDA80X90B is a double-acting single-rod compact cylinder engineered to deliver a robust 2513.3 N push force at 0.5 MPa. By utilizing a riveted assembly that permanently joins the barrel, rear cover, piston, and rod, this unit achieves an exceptionally short axial profile. This space-saving footprint is critical for machinery where a conventional round-body actuator would protrude too far into the work envelope.
This specific SKU is configured with a male M22x1.5 piston rod thread (denoted by the B option code) for secure mechanical coupling to your tooling. The 80 mm bore necessitates PT3/8 air ports and carries a 25 mm rod diameter to handle high thrust loads. Deceleration at the stroke extremes relies on 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 ejector pins on large plastic injection molding machines, utilizing the 3518.6 N extend force at 0.7 MPa to break parts free from deep cavities.
Actuates hold-down clamps on an automated press brake, where the male M22x1.5 rod end secures custom tooling and the compact body minimizes machine footprint.
Provides the vertical lifting thrust for heavy product diverters on palletizing conveyors, moving loads safely within the 128.1 kg vertical lift margin.
When sizing this 80 mm bore actuator, evaluate your thrust requirements carefully. Stepping down to the SDA63 yields 1558.6 N of push force at 0.5 MPa, whereas stepping up to the SDA100 provides 3927 N. For the SDA80X90B, the computed safe working load is approximately 1508 N (about 60 percent of the 0.5 MPa rating), translating to a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin. Ensure your ordering essentials match this configuration: an 80 mm bore, 90 mm stroke, PT3/8 ports, a male M22x1.5 rod end, and no piston magnet. Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops or the valve is centered—the piston will drift, as the fixed NBR bumper only decelerates the stroke end rather than locking it. To suspend a load safely without live pressure, integrate an external rod lock or a 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, and 3518.6 N push at 0.7 MPa. The theoretical maximum push force is 513 kgf at 1.0 MPa. It operates on filtered air between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa.
This specific SKU lacks a piston magnet, so it cannot accept AirTAC reed or electronic switches. End-of-stroke deceleration is handled by a fixed NBR bumper, not a field-adjustable air cushion; for high-energy cycles, add external shock absorbers.
