Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-20
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-20 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 65 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-20
The AirTAC SDAJ100X85-20 is a compact double-acting single-rod cylinder engineered with an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the forward end-position anywhere between 65 and 85 mm directly on the machine, avoiding part swaps during changeovers. Because the adjuster only sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering about 3927 N push at 0.5 MPa.
This 100 mm bore actuator features a short riveted body that drastically reduces axial mounting depth compared to conventional round-body or profile cylinders, fitting into tight 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 speed spans 30-500 mm/s, and the PT3/8 air port is paired with a robust 32 mm piston rod to handle high thrust loads.

| 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 20 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 SDAJ100X85-20 Is Used
Heavy Press Fitment
Dial the extend stop between 65 and 85 mm to set precise contact depth for pressing bearings without swapping physical shims.
Vertical Lifting Jigs
Lifts up to 200.2 kg safely using the 2:1 margin, with the fixed NBR bumper absorbing the shock at the upper travel limit.
Short-Depth Assembly Stations
Saves valuable axial mounting space in compact machinery frames while delivering 3927 N of thrust for heavy part seating.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-20 the Right Cylinder?
When sizing this actuator, evaluate your thrust requirements bidirectionally. If 2513.3 N of push at 0.5 MPa from the SDAJ80 bore is sufficient, stepping down saves significant axial length. If you require maximum thrust, this 100 mm bore yields a theoretical 801 kgf at 1.0 MPa. For this specific SKU, a safe working load is roughly 2356 N, equating to a vertical lift capacity of about 200.2 kg with a 2:1 safety margin.
This model is ideal for operators needing on-site stroke tuning to perfect a pressing or lifting motion. Note 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 end of the stroke, so integrate an external rod lock or pilot-operated check valve for suspended loads. This configuration includes a 100 mm bore, 85 mm stroke, 20 mm adjust window, PT3/8 port, female M18x1.5 rod-end thread, and no piston magnet.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 65–85 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 SDAJ100X85-20 FAQ
This 100 mm bore cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, push is 5497.8 N and pull is 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The external M27x2.0 adjuster screw mechanically shortens the extend stroke by up to 20 mm, allowing you to set the forward stop anywhere from 65 to 85 mm. It does not alter the thrust force, and retract remains full stroke.
