The AirTAC AirTAC SDA100X65 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 SDA100X65 is a double-acting, single-rod compact cylinder engineered for heavy-duty pneumatic motion within a minimal axial footprint. Its riveted assembly of the barrel, rear cover, piston, and rod drastically reduces overall length compared to conventional round-body units, yielding a space-saving machine layout. Operating at 0.15-1.0 MPa, it generates a 3927 N push and 3524.9 N pull at 0.5 MPa.
This 100 mm bore unit features a robust 32 mm piston rod and PT3/8 air ports. The hard-anodized inner wall minimizes friction, while end-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable cushion. Because this specific SKU lacks the S option, it has no piston magnet and cannot host sensing switches.

Supplies the high 3927 N extend force needed to push heavy plastic parts out of large injection molding tools within a tight press envelope.
Drives large bearings or bushings into heavy machinery housings, utilizing the 32 mm rod to maintain rigidity during high-force insertion tasks.
Indexes thick metal stock into a mechanical stamping press, where the short 65 mm stroke and fixed NBR bumpers handle rapid cyclic loading.
When sizing this actuator, stepping down to the SDA80 provides 2513.3 N of push force at 0.5 MPa, whereas this SDA100X65 tops out at 3927 N under identical pressure. As the largest standard bore in the SDA family, it represents the maximum thrust tier before exploring alternative body styles. A computed safe working load is approximately 2356 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centered; the fixed bumper only slows the piston near stroke end and does not function as a locking brake. To suspend a load safely without live pressure, incorporate an external rod lock or a pilot-operated check valve. To order, confirm the 100 mm bore, 65 mm stroke, PT3/8 porting, female M18x1.5 rod thread, and the absence of a magnet.
Quick checklist
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3524.9 N of pull force. At 0.7 MPa, push increases to 5497.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa, and the maximum standard stroke available for this bore is 130 mm.
No. The SDA series uses a fixed NBR bumper at each end to decelerate the stroke, not a field-adjustable air cushion. Additionally, this specific SKU lacks the S magnet option, meaning it cannot accept reed or electronic switches; you must select an SDA100X65S variant for position sensing.
