The AirTAC AirTAC SDA40X60BH Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 60mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA40X60BH is a double-acting, single-rod compact cylinder engineered with a 40 mm bore and 60 mm stroke. It provides a robust 628.3 N push force alongside 527.8 N pull force at 0.5 MPa. The riveted body assembly significantly reduces axial mounting depth compared to conventional round-body units, making it highly effective for machinery where space savings are critical. This specific SKU includes an FKM fluororubber seal variant for enhanced thermal and oil resistance.
Equipped with a male M14x1.5 threaded piston rod, this model ensures a solid mechanical coupling to your load. The bore features a hard-anodized inner wall and operates at speeds between 30-500 mm/s. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning high-energy cycles may require an external shock absorber. Note that this configuration lacks a piston magnet, so position sensing is not supported without switching to an -S variant.

Secures aluminum housings inside CNC machining centers. The male M14x1.5 rod threads directly into custom tooling, delivering 628.3 N of clamping force at 0.5 MPa.
Folds corrugated cardboard flaps on automated packaging lines. The compact riveted body minimizes frame intrusion while the FKM seals withstand occasional lubricant exposure.
Actuates routing gates on conveyor sortation systems. The fixed NBR bumper effectively absorbs the 60 mm stroke impact without requiring external adjustment.
When sizing this actuator, stepping down to the SDA32 yields 402.1 N of push force at 0.5 MPa, whereas stepping up to the SDA50 provides 981.7 N at the same pressure. This 40 mm bore strikes a balance, offering a safe working load of roughly 377 N (about 60% of its 0.5 MPa capacity) and a vertical lift capability near 32 kg with a 2:1 safety margin. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; if your application demands strict position holding, you must integrate an external rod lock or a pilot-operated check valve. To order, confirm the 40 mm bore, 60 mm stroke, PT1/8 port, male M14x1.5 rod end, FKM seals, and no magnet.
Quick checklist
This 40 mm bore double-acting cylinder delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, the push force is 879.6 N. The theoretical maximum push force is 128 kgf at 1.0 MPa, which is the maximum operating pressure.
No, this specific SKU lacks the internal piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to select the -S option to enable sensor groove functionality. Additionally, the male M14x1.5 rod end replaces the standard female M8x1.25 thread.
