The AirTAC AirTAC SDA100X75 Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 75mm 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 SDA100X75 is a double-acting single-rod compact cylinder engineered for heavy-duty pneumatic actuation within a minimal axial footprint. It delivers a substantial 3927 N push and 3524.9 N pull force at 0.5 MPa, utilizing a hard-anodized 100 mm bore and a robust 32 mm piston rod. The riveted unibody design integrates the barrel and covers to drastically reduce overall length compared to conventional round-body actuators.
This model features a PT3/8 air port and a female M18x1.5 rod-end thread, making it highly suitable for securely coupling heavy loads. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycles. Note that this specific SKU lacks a piston magnet and therefore cannot support magnetic position sensing.

Provides the heavy 3927 N extension force needed to knock thick steel blanks from progressive stamping dies in automotive fabrication lines.
Raises heavy layered product loads in end-of-line packaging machinery where the short 75 mm stroke and compact body depth conserve vertical machine space.
Secures heavy mold halves in plastic injection equipment, utilizing the 32 mm rod and female M18x1.5 thread for rigid load coupling without side-load deflection.
When sizing your pneumatic drive, stepping down to the SDA80 yields 2513.3 N of push force at 0.5 MPa, whereas this SDA100 provides the maximum standard thrust in the series at 3927 N. For this 100 mm bore, the computed safe working load is approximately 2356 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 200.2 kg with a 2:1 safety margin. Ensure your ordering essentials are correct: 100 mm bore, 75 mm stroke, PT3/8 port, female rod thread, and no sensor magnet. If your machinery must maintain vertical position during air loss or valve centering, be aware this cylinder will drift; an external rod lock or pilot-operated check valve is required to hold the load securely.
Quick checklist
This 100 mm bore double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa, increasing to 5497.8 N push at 0.7 MPa. The theoretical maximum thrust is 801 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, end-stop deceleration relies on a fixed NBR bumper, not a field-adjustable air cushion, so external shock absorbers are advised for high-speed impacts. Additionally, this SKU lacks a piston magnet; you must select an -S variant to use AirTAC reed or electronic switches.
