The AirTAC AirTAC SDA80X25S 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 SDA80X25S is a double-acting single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly abbreviated unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too bulky. The 80 mm bore features a hard-anodized inner wall and a two-way piston seal for prolonged operational life.
This specific configuration includes the S option, meaning a built-in piston magnet enables position detection via an AirTAC reed or electronic switch seated in the body grooves. The 25 mm stroke is governed by a fixed NBR bumper at each end that decelerates the end stop; it is not an adjustable air cushion. Because the bumper cannot lock the piston, any vertical lift application around 128.1 kg with a 2:1 margin requires an external rod lock or pilot-operated check valve to prevent drifting when air pressure drops.

Drives short-stroke ejection pins inside tight mold platen recesses, utilizing the abbreviated body depth to fit within machinery where axial clearance is severely restricted.
Provides 2513.3 N of extend force at 0.5 MPa for light-duty stamping or press-forming operations, with the PT3/8 port handling the necessary air volume for rapid cycling.
Pushes loaded pallets onto adjacent conveyor lanes within high-throughput logistics lines, relying on the 25 mm stroke and integrated magnet for precise end-position confirmation.
When sizing this actuator, 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. For this 80 mm bore, the standard maximum stroke reaches 130 mm, so a 25 mm travel fits well within the compact body's intended short-stroke envelope. To finalize your order, confirm the 80 mm bore, 25 mm stroke, PT3/8 port, female M14x1.5 rod-end thread, and the S magnet option. If your mechanism demands male threading, specify the B code for an M22x1.5 rod end.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered. The fixed NBR bumper only absorbs impact near the stroke endpoints rather than holding the load, so integrate a separate locking mechanism if your machinery requires fail-safe positioning.
Quick checklist
This double-acting single-rod 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 and pull to 3175 N. The theoretical maximum push is 513 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and a proof pressure of 1.5 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a braking lock. The S option equips the piston with a magnet for use with AirTAC reed or electronic switches in the body grooves, and the 25 mm stroke operates at speeds between 30 and 500 mm/s.
