The AirTAC SDA63X75SBH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 75mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA63X75SBH is a double-acting, single-rod compact cylinder engineered with a 63 mm bore and a 75 mm stroke. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, this unit achieves a remarkably short axial footprint, saving valuable mounting depth in tight machinery layouts compared to conventional round-body units. It delivers a robust 1558.6 N push force at 0.5 MPa, alongside a 1401.5 N pull force.
This specific configuration includes the S option for a built-in piston magnet compatible with AirTAC reed or electronic switches, and the B option, providing a male M18x1.5 threaded piston rod for secure load coupling. The H designation indicates fluororubber (FKM) seals for enhanced thermal and oil resistance. End-stopping relies on a fixed NBR bumper to decelerate the stroke, meaning it is not an adjustable air cushion. For high-energy cycles, operators should add external shock absorbers or slow the approach speed.

Drives the ejection plate inside a plastic injection molding machine, utilizing the 1558.6 N extend force to reliably strip finished parts while the FKM seals withstand ambient heat.
Folds corrugated cardboard flaps on high-speed packaging lines, where the 75 mm stroke and space-saving riveted body fit neatly within the conveyor side frame.
Positions lower die rails on a CNC press brake, using the male M18x1.5 rod end for rigid attachment and the magnetic piston for precise stroke-end confirmation.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the valve is centered; the fixed bumper only decelerates near the stroke end and acts as neither a lock nor a brake. For suspended loads, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 63 mm bore, 75 mm stroke, PT1/4 port, male M18x1.5 rod, the FKM seal option, and the integrated magnet.
Quick checklist
This double-acting 63 mm bore cylinder provides 1558.6 N push and 1401.5 N pull at 0.5 MPa, increasing to 2182.1 N push and 1962.2 N pull at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30 to 500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. If your cycle generates high kinetic energy, you should slow the approach or install an external shock absorber. Furthermore, the bumper is not a locking device; the piston will drift on air loss, so a pilot-operated check valve or external rod lock is required to hold a suspended load.
