The AirTAC AirTAC SDA63X45BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 45mm 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 SDA63X45BH is a double-acting, single-rod compact cylinder engineered for tight axial spaces. A riveted assembly of the barrel, rear cover, piston, and rod drastically reduces mounting depth compared to round-body units. At 63 mm bore, it generates 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. This specific SKU includes an -H fluororubber (FKM) seal for upgraded thermal and oil resistance.
This model features a -B male-thread piston rod (M18x1.5) for secure mechanical load coupling, paired with a 20 mm rod diameter and PT1/4 ports. It lacks a piston magnet, so position sensing is not supported here. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow high-speed approaches or utilize external shock absorbers to dissipate kinetic energy safely.

Drives heavy corrugated cases onto palletizing lanes with 1558.6 N of extend force, utilizing the FKM seals to withstand warm packaging environments.
Employs the male M18x1.5 rod end to securely attach ejection plates, providing robust 1401.5 N retraction force within tight machinery frames.
Positions heavy-gauge sheet metal backstops accurately, where the short 63 mm riveted body conserves valuable floor space and machine footprint.
When sizing this actuator, stepping down to an SDA50 yields 981.7 N of push at 0.5 MPa, while stepping up to an SDA80 provides 2513.3 N. For this 63 mm bore, the safe working load is approximately 935 N (about 60% of the 1558.6 N figure), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Because a standard compact cylinder drifts when air pressure is lost or the valve is centered, applications requiring suspended load holding must integrate an external rod lock or a pilot-operated check valve. To order, confirm the 63 mm bore, 45 mm stroke, PT1/4 port, male M18x1.5 rod thread, FKM seals, and no magnet.
Quick checklist
This 63 mm bore double-acting cylinder outputs 1558.6 N push and 1401.5 N pull at 0.5 MPa, and 2182.1 N push at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not have the -S option, meaning it lacks a piston magnet and cannot trigger AirTAC reed or electronic switches. You would need the SDA63X45SBH variant to utilize the body's integrated sensor grooves.
