The AirTAC AirTAC SDA40X60SBG 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 SDA40X60SBG is a double-acting, single-rod compact cylinder engineered to deliver 628.3 N of push force at 0.5 MPa. Its short riveted body minimizes axial mounting depth, allowing it to slot into tight machine footprints where standard round-body units fail to fit. The hard-anodized bore and two-way piston seal ensure durable, consistent linear motion.
This configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It features a male M14x1.5 threaded piston rod (-B) for secure mechanical coupling, and utilizes a PT1/8 port modified to BSPP (-G). End-stops rely on a fixed NBR bumper that decelerates the piston near stroke limits rather than an adjustable air cushion.

Drives the Z-axis plunge on a printed circuit board depaneling router, utilizing the 60mm stroke and 628.3 N force to cleanly cut substrates within a compact gantry frame.
Folds minor corrugated box flaps on a continuous packaging line, where the male M14x1.5 rod securely mounts the folding arm and the short body conserves conveyor side-frame space.
Ejects small stamped metal brackets from a progressive die bed, relying on the fixed NBR bumper to absorb the 30-500 mm/s cycle impact without requiring an adjustable cushion.
When sizing this unit, evaluate your force margins: stepping down to the SDA32 yields 402.1 N push at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N. For the 40mm bore, a safe working load is approximately 377 N (about 60% of the 628.3 N capacity), translating to a vertical lift capability of roughly 32 kg with a 2:1 safety margin. Keep in mind a plain compact cylinder drifts when air is lost or the valve centers, as the fixed bumper only decelerates near stroke end rather than locking the load; utilize an external rod lock or pilot-operated check valve if position holding is critical. Confirm your ordering essentials: 40mm bore, 60mm stroke, BSPP port, male M14x1.5 rod, and the integrated sensor magnet.
Quick checklist
At 0.5 MPa this 40mm bore cylinder provides 628.3 N push and 527.8 N pull. At 0.7 MPa it provides 879.6 N push and 738.9 N pull. The theoretical maximum push is 128 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, it does not hold its load when air is lost or the valve is centered; the piston will drift. An external rod lock or pilot-operated check valve is required for position holding.
