The AirTAC AirTAC SDA100X55B Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 55mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA100X55B is a double-acting, single-rod compact cylinder engineered to deliver substantial thrust in a minimal axial footprint. It generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, utilizing a hard-anodized 100 mm bore and a robust 32 mm piston rod. The riveted body design integrates the barrel and covers to drastically reduce overall length compared to conventional round-body units, making it highly effective for machinery where space savings are critical.
This specific configuration includes the -B option, providing a male M26x1.5 threaded rod end for secure mechanical load coupling, and uses a PT3/8 port. Deceleration at the stroke extremes is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be added for high-energy impacts. Because this SKU lacks the -S magnet option, it cannot support magnetic position sensing.

Provides the high 3927 N push force required to eject dense plastic parts from injection molding tools, utilizing the short riveted body to fit within tight mold platen depths.
Drives press brakes or bending jigs for thick sheet metal, where the male M26x1.5 rod end securely attaches to heavy tooling without shearing under 5497.8 N of thrust at 0.7 MPa.
Lifts lower pallet stages in compact packaging lines, offering a 200.2 kg vertical lift capacity with a 2:1 safety margin while conserving vertical machinery space.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA80 yields 2513.3 N of push at 0.5 MPa, whereas this SDA100 provides 3927 N, and represents the maximum bore in the series. A computed safe working load is roughly 2356 N (about 60% of the 0.5 MPa figure), which translates to a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin.
Ensure your ordering essentials match the application: 100 mm bore, 55 mm stroke, PT3/8 port, male M26x1.5 rod thread, and no sensor magnet. Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed NBR bumper only decelerates the stroke end without locking the load; utilize an external rod lock or pilot-operated check valve if position holding is mandatory.
Quick checklist
At 0.5 MPa, the push force is 3927 N and the pull force is 3524.9 N. At 0.7 MPa, the push force is 5497.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the operating speed ranges from 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; for high-speed cycling, you should add external shock absorbers. Furthermore, it does not hold its load if air is lost, as the bumper is not a braking device—an external rod lock or pilot-operated check valve is required for position holding.
