The AirTAC AirTAC SDA80X40B Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 40mm 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 SDA80X40B is a double-acting single-rod compact cylinder engineered to deliver 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa. Its short riveted body significantly reduces axial mounting depth compared to round-body units, conserving machine footprint in heavy-duty setups. The unit features a hard-anodized bore and operates at speeds between 30 and 500 mm/s.
This specific SKU includes a male M22x1.5 threaded piston rod for robust mechanical coupling to your load. It relies on a fixed NBR bumper at each end to decelerate the stroke end, meaning it is not an adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Drives heavy stamping dies in automotive assembly cells where the 2513.3 N push force securely positions steel panels before the main hydraulic cycle begins.
Pushes empty wooden pallets into the loading bay of high-speed packaging lines, utilizing the 40 mm stroke to clear the feed track quickly.
Applies holding pressure on thick sheet metal brackets during an industrial bending press operation, leveraging the 25 mm male-threaded rod for a rigid tooling connection.
When sizing this actuator, stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, while stepping up to the SDA100 provides 3927 N. Based on the 2513.3 N output at 0.5 MPa, the safe working load is approximately 1508 N (about 60 percent of capacity), translating to a vertical lift capability of roughly 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80 mm bore, 40 mm stroke, PT3/8 port, and the male M22x1.5 rod thread. Remember that a plain compact cylinder drifts when air pressure is lost or a valve is centered; the fixed bumper only decelerates near the stroke end and acts as neither a lock nor a brake. To hold a load securely without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 2513.3 N of push and 2267.8 N of pull at 0.5 MPa. At 0.7 MPa, the push increases to 3518.6 N. The theoretical maximum push is 513 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, handles a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; this is not a field-adjustable air cushion, so external shock absorbers are recommended for high-energy cycles. Additionally, this specific SKU lacks the -S magnet, meaning it cannot support AirTAC reed or electronic switches without changing to a magnet-equipped variant.
