The AirTAC AirTAC SDA100X55SBH 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 SDA100X55SBH is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted body assembly significantly reduces mounting depth compared to conventional round-body units, yielding a robust 3927 N push force at 0.5 MPa. This specific configuration includes a male M26x1.5 piston rod end for secure mechanical load coupling, a built-in piston magnet for position sensing, and high-temperature fluororubber (FKM) seals for enhanced oil and thermal resistance.
Designed with a 100 mm bore and a 55 mm stroke, this model relies on a fixed NBR bumper at each end to decelerate the stroke rather than an adjustable air cushion. The hard-anodized inner bore ensures long service life, while the integrated magnetic grooves accommodate AirTAC reed or electronic switches. Because the bumper is not a locking device, the piston will drift if air pressure is lost, requiring an external rod lock for strict position holding.

Drives heavy mold ejection plates in plastic injection machinery where the compact riveted body saves axial space and the FKM seals withstand elevated ambient heat.
Pushes thick gauge metal stock into stamping presses, utilizing the 3927 N extend force and the rigid 32 mm male-threaded rod for secure tooling attachment.
Raises loaded pallets in packaging lines, relying on the 200.2 kg vertical lift capacity while external guides prevent side-load damage to the short actuator body.
When sizing this 100 mm bore actuator, consider stepping down to the SDA80, which provides 2513.3 N of push force at 0.5 MPa for lighter loads, or stepping up if your application exceeds the 801 kgf theoretical maximum at 1.0 MPa. The computed safe working load for this SDA100X55SBH is approximately 2356 N (about 60% of the 3927 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 200.2 kg with a 2:1 safety margin. To finalize your order, confirm the 100 mm bore, 55 mm stroke, PT3/8 port, male M26x1.5 rod thread, the -S magnet requirement, and the -H FKM seal option. If your system must maintain vertical load positioning without live pressure, add a pilot-operated check valve or external braking mechanism.
Quick checklist
This double-acting 100 mm bore cylinder generates a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, the push force is 5497.8 N and the pull is 4934.8 N. The theoretical maximum push force is 801 kgf at the 1.0 MPa pressure limit.
It uses a fixed NBR bumper at each end to absorb impact, which is not an adjustable air cushion; for high-speed operations, you should add an external shock absorber. Additionally, the bumper is not a brake, so the piston will drift on air loss and requires an external rod lock to hold a load securely.
