Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50 is a genuine double-acting COMPACT cylinder (Ø100mm bore) whose extend end-position is set by an external M27×2.0 adjustment screw. You can dial the stroke anywhere from 25 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50
The AirTAC SDAJ100X75-50 is a compact double-acting single-rod cylinder engineered for heavy-duty positioning where the extend end-point must be dialed in on the machine. An external M27x2.0 adjuster screw lets you shorten the forward stroke by up to 50 mm, yielding a usable extend range of 25 to 75 mm without swapping shims or parts. Because the adjuster merely sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
Built with a short riveted body, this unit saves substantial axial mounting depth compared to conventional round-body or profile alternatives, fitting into tight high-force machinery footprints. End-of-travel deceleration is handled by a fixed NBR bumper at each end, which absorbs shock but is not an adjustable air cushion. Operating pressure spans 0.15 to 1.0 MPa, and the PT3/8 air port feeds a 32 mm piston rod designed to handle substantial loads.

| Speed range | 30 – 500 mm/s |
| Cushion | Fixed NBR bumper (both ends) |
The adjustment screw shortens the extend stroke by up to 50 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3525 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
Force matches a standard SDA of the same bore; the adjuster only sets the stop position, not the area. Actual usable force is lower than theoretical due to friction.

Where the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50 Is Used
Heavy Press Tuning
Dial in the 25 to 75 mm extend stop on-site to set precise 3927 N clamping depth for heavy metal-forming presses without changing hardware.
Compact Riveting Cell
Leverage the short riveted body to fit high-force 100 mm bore actuation into tight robotic cells, using the fixed NBR bumper to absorb end shock.
Vertical Lift Jig
Lift payloads up to 200.2 kg with a 2:1 safety margin at 0.5 MPa, adjusting the mechanical stop to set exact raising heights during changeovers.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50 the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force needs bidirectionally. Stepping down, the SDAJ80 provides 2513.3 N of push at 0.5 MPa, making this SDAJ100X75-50 the correct upgrade when your application demands the full 3927 N push. Based on the 0.5 MPa figure, a safe working load is approximately 2356 N (about 60 percent of capacity), translating to a vertical lift capability of roughly 200.2 kg with a 2:1 safety margin. Confirm your required extend window is 25 to 75 mm, the PT3/8 port is compatible, and note this specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches without the -S option.
This model excels in setup-heavy lines requiring frequent on-machine stroke tuning to dial in exact pressing or clamping positions. Remember that a plain cylinder does not hold its load upon air loss or valve centering; the piston drifts, and the fixed bumper only decelerates near the stroke end rather than locking. For suspended or vertical loads that must be held without live pressure, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–75 mm
- ✓ Force at your working pressure
- ✓ Access to reach the R adjuster
- ✓ Magnet (S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the M27×2.0 adjuster after setting the stroke.
- check Avoid side load on the piston rod.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50 FAQ
This 100 mm bore double-acting cylinder features a PT3/8 air port and a 32 mm rod. It delivers 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum push of 801 kgf at 1.0 MPa.
The M27x2.0 external screw mechanically shortens the extend stroke by up to 50 mm, allowing on-machine tuning between 25 and 75 mm. This screw sets the stop position and does not alter force; it is not a mid-stroke lock, so the cylinder cannot hold a load without live air pressure.
