The AirTAC AirTAC SDA100X65B Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 65mm 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 SDA100X65B is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted assembly reduces overall length compared to traditional round-body units, yielding a substantial 3927 N push force at 0.5 MPa. This specific SKU features a robust 32 mm piston rod and a male M26x1.5 thread for secure mechanical coupling to your load.
Deceleration at stroke limits relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or utilize external shock absorbers for high-energy cycles. Because this configuration lacks the -S magnet option, it cannot support magnetic position sensing. Furthermore, the unit will not hold a load if air pressure drops; implement an external rod lock or pilot-operated check valve if static positioning is mandatory.

Drives heavy ejector pins on large injection molding platens, utilizing the 5497.8 N extend force at 0.7 MPa to break stubborn parts free from deep cavities.
Positions heavy steel blanks within an automotive stamping press, where the male M26x1.5 rod end secures the tooling and the compact body minimizes press frame protrusion.
Elevates loaded pallets in high-throughput packaging lines, safely managing vertical lifts near 200.2 kg when operated within the recommended 2:1 safety margin.
Selecting this 100 mm bore provides immense thrust, but evaluating neighboring sizes ensures optimal sizing. Stepping down, the SDA80 offers 2513.3 N push at 0.5 MPa, which may suffice for lighter fixtures and conserve space. Moving up is unnecessary as this represents the largest standard SDA bore. With a safe working load around 2356 N (60% of the 0.5 MPa rating) and a vertical lift capacity of roughly 200.2 kg at a 2:1 safety margin, verify your dynamics carefully.
When ordering, confirm the 65 mm stroke, PT3/8 porting, and the -B male M26x1.5 rod end. Remember that the fixed NBR bumper only decelerates the piston near the end of travel; it functions strictly as an impact absorber, never as a braking mechanism to hold position during air loss.
Quick checklist
This 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 increases to 5497.8 N. The theoretical maximum push is 801 kgf at the 1.0 MPa operating pressure limit.
No, this specific SKU does not include the -S magnet option, so it cannot trigger AirTAC reed or electronic switches. You must specify an SDA100X65BS variant to enable magnetic position sensing via the body grooves.
