The AirTAC AirTAC SDA25X25BH Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 25mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA25X25BH is a double-acting, single-rod compact cylinder engineered to deliver 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. Its riveted body design integrates the barrel, rear cover, piston, and rod into a highly space-efficient package, drastically reducing axial mounting depth compared to conventional round-body units. This specific configuration includes a male M8x1.25 piston rod end for straightforward load coupling, paired with a fluororubber (FKM) seal for enhanced thermal and oil resistance.
The 25 mm bore features an M5x0.8 air port and a 10 mm rod, operating at speeds from 30-500 mm/s. Instead of an adjustable air cushion, the piston strikes a fixed NBR bumper at each end to absorb end-stop energy. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches without modification.

Actuates the cutting head on an electronics assembly line, utilizing the 25 mm stroke and male M8 thread to securely hold the routing spindle while managing localized cutting forces.
Provides the 245.4 N push force required to close a heated sealing die, with FKM seals surviving the elevated ambient temperatures near the heating platens.
Pushes plastic containers from a main conveyor belt into a secondary labeling lane, where the short riveted body minimizes the footprint inside the tight machinery guarding.
When sizing this unit, consider stepping down to the SDA20, which provides 157.1 N of push force at 0.5 MPa, or moving up to the SDA32, which yields 402.1 N at the same pressure. With a 245.4 N output at 0.5 MPa, the safe working load is approximately 147 N (about 60 percent of capacity), translating to a vertical lift capability of roughly 12.5 kg with a 2:1 safety margin. Be aware that a standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke near its end and does not function as a locking brake. To hold a load securely without live pressure, you must integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 25 mm bore, 25 mm stroke, M5x0.8 port, male M8x1.25 rod thread, and FKM seals.
Quick checklist
This double-acting 25 mm bore cylinder generates 245.4 N push and 206.2 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 343.6 N. The theoretical maximum push force is 50 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, has a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, this specific SKU does not include the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. Additionally, the end caps use a fixed NBR bumper to decelerate the piston rather than an adjustable air cushion, so for high-speed operations you may need to slow the approach or add external shock absorbers.
