Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-40
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-40 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 60 to 100 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-40
The AirTAC SDAJ100X100-40 is a compact double-acting single-rod cylinder built for heavy-duty positioning where the extend endpoint must be dialed in on the machine. An external M27x2.0 adjuster screw lets you shorten the forward stroke by up to 40 mm, yielding a usable travel range of 60 to 100 mm without swapping shims or parts. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, providing 3927 N of push at 0.5 MPa.
This 100 mm bore unit features a robust 32 mm piston rod and a PT3/8 air port to handle substantial loads. The short riveted body saves valuable axial mounting depth compared to conventional round-body or profile cylinders, fitting into tighter machinery envelopes. End-of-travel deceleration is handled by a fixed NBR bumper at each end, which absorbs shock but is not 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 variant.

| Cushion | Fixed NBR bumper (both ends) |
The adjustment screw shortens the extend stroke by up to 40 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 SDAJ100X100-40 Is Used
Heavy Press Fitments
Ideal for dialing in precise 60-100 mm press depths on heavy assemblies, using the full 3927 N push at 0.5 MPa to seat bearings without over-traveling.
Multi-Product Clamping Lines
Enables rapid changeover on machining fixtures by turning the M27x2.0 external screw to match varying part heights, eliminating the need to swap cylinder shims.
Vertical Lift Stations
Handles vertical lifting tasks up to roughly 200.2 kg with a 2:1 safety margin, allowing operators to fine-tune the extend stop to prevent collision with upper tooling.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-40 the Right Cylinder?
Selecting this 100 mm bore actuator involves sizing against its neighbors to ensure the load fits the force profile. Dropping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, which may be insufficient for heavy lifting, whereas this 100 mm option provides a robust 3927 N. If your application requires even more power, moving up to a larger bore is necessary, as this represents the top of the standard SDAJ range. With a theoretical maximum output of 801 kgf at 1.0 MPa, this model is suited for high-force clamping and pressing.
Engineers who require frequent changeovers or trial positioning will benefit from the 60-100 mm on-site adjustability. Based on the 0.5 MPa push rating, a safe working load is approximately 2356 N (about 60 percent of capacity), allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin. Remember that a plain SDAJ does not hold position or load when air is lost or the valve is centered; the fixed bumper only decelerates near the end of travel. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your requirements for bore, stroke, window, PT3/8 port, rod thread (female M18x1.5 or male M26x1.5), and magnet status before ordering.
Quick checklist

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 SDAJ100X100-40 FAQ
This 100 mm bore double-acting cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push force is 801 kgf at 1.0 MPa. It uses a PT3/8 air port and a 32 mm piston rod.
The external M27x2.0 screw acts as a mechanical stop that shortens the extend stroke by up to 40 mm, giving an adjustable travel range of 60 to 100 mm on-site. This SKU does not include a piston magnet and cannot accept switches; you must select the -S magnet option to use AirTAC reed or electronic sensors.
