The AirTAC AirTAC SDA40X60SB 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 SDA40X60SB is a double-acting, single-rod compact cylinder engineered to deliver 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. Its riveted body assembly significantly reduces axial mounting depth compared to traditional round-body units, making it highly effective for machinery where space footprint is critical. The 40 mm bore features a hard-anodized inner wall and operates on filtered 40 um air.
This specific configuration includes a built-in piston magnet (-S) for position sensing via AirTAC reed or electronic switches mounted in the body grooves, and a male M14x1.5 threaded piston rod end (-B) for direct load coupling. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Operating speed ranges from 30-500 mm/s across a 0.15-1.0 MPa pressure range.

Secures aluminum engine blocks during CNC machining, utilizing the 628.3 N extend force and male M14x1.5 rod to pull a jaw clamp tight against the part profile.
Drives mechanical arms to fold corrugated cardboard flaps on automated packaging lines, where the 60 mm stroke and compact riveted body minimize frame interference.
Actuates a routing diverter on a parcel handling conveyor, using the built-in magnet and a reed or electronic switch to confirm gate position before packages arrive.
When sizing this unit, evaluate stepping down to the SDA32 bore, which provides 402.1 N of push force at 0.5 MPa, or moving up to the SDA50 bore, which yields 981.7 N at the same pressure. For the SDA40X60SB, a practical safe working load is approximately 377 N (about 60% of the 628.3 N figure), translating to a vertical lift capacity of roughly 32 kg with a 2:1 safety margin. Ensure your ordering essentials match the 40 mm bore, 60 mm stroke, PT1/8 port, male M14x1.5 rod thread, and the required sensor magnet. Note that a standard cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. If your application must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting single-rod cylinder generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum push force is 128 kgf at 1.0 MPa. It operates on air filtered to 40 um, with a pressure range of 0.15-1.0 MPa, proof pressure of 1.5 MPa, and a speed range of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston near the stroke limits; this is not an adjustable air cushion, so external shock absorbers are recommended for high-energy cycles. Additionally, the bumper is not a locking device. The piston will drift if air pressure drops or the valve is centered, so an external rod lock or pilot-operated check valve is required to hold a load securely.
