Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-50
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-50 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 20 to 70 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-50
The AirTAC SDAJ100X70-50 is a double-acting, single-rod compact cylinder featuring an external adjustable extend stop. An M27x2.0 adjuster screw lets you dial the outward stroke anywhere between 20 and 70 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. Retract remains full length, while the mechanical stop sets the position without altering the pneumatic force.
Delivering 3927 N of push at 0.5 MPa, this 100 mm bore unit matches the output of a standard SDA while saving valuable axial mounting depth through its short riveted body. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S option.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-50 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 70 mm |
| Adjustable range | 20 – 70 mm |
| Adjuster thread (R) | M27×2.0 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M18×1.5 F / M26×1.5 male (B) |
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| 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 SDAJ100X70-50 Is Used
Heavy Press Tuning
Dial the 20-70 mm extend stop on the fly to set precise contact pressure for heavy pressing operations without changing machine hardware.
Multi-Product Forming Lines
Leverage the 3927 N push at 0.5 MPa to form thick materials, adjusting the outward reach quickly during product changeovers to accommodate different blank thicknesses.
Vertical Lift Dampening
Lift loads up to 200.2 kg with a 2:1 margin; pair it with external shock absorbers if the approach speed generates too much kinetic energy for the fixed NBR bumper.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-50 the Right Cylinder?
When sizing this model, evaluate your force requirements both ways. Stepping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, which may undershoot heavy loads, whereas this 100 mm bore provides a safe working load of roughly 2356 N (about 60% of its 3927 N capacity) and a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin. Choose the 100 mm bore when you need maximum thrust within a compact footprint.
This cylinder is ideal for setups requiring frequent on-site stroke tuning between 20 and 70 mm. Confirm your port size is PT3/8 and your rod-end thread is female M18x1.5 (or male M26x1.5 if specified). Because a plain cylinder drifts when air is lost or the valve is centered, integrate an external rod lock or pilot-operated check valve if your application requires load holding.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 20–70 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 SDAJ100X70-50 FAQ
This 100 mm bore cylinder features a PT3/8 air port and delivers 3927 N push / 3524.9 N pull at 0.5 MPa, 5497.8 N push / 4934.8 N pull at 0.7 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa.
The M27x2.0 adjuster screw mechanically shortens the extend stroke by up to 50 mm, allowing you to set the outward stop anywhere between 20 and 70 mm. It acts only as a physical stop and does not alter the cylinder's pneumatic force or lock the piston mid-stroke.
