Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X15-20B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X15-20B 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 0 to 15 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X15-20B
The AirTAC SDAJ100X15-20B is a compact double-acting single-rod cylinder built for tight axial spaces, featuring a short riveted body that saves mounting depth where larger profile cylinders fail to fit. It uses an external R (M27x2.0) adjuster screw to dial the extend stop down to 0-15 mm on-site, providing exact positioning without shims or part changes. Because the adjuster sets the mechanical stop rather than the piston area, force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
This specific SKU includes a male-thread piston rod (M26x1.5) for secure external mounting and operates on a PT3/8 air port. 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 base model lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X15-20B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 15 mm |
| Adjustable range | 0 – 15 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 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 SDAJ100X15-20B Is Used
Heavy-Duty Pin Pressing
Dial in the exact 0-15 mm extend stop on the factory floor to seat large pins without over-travel, leveraging the 3927 N push force for reliable insertion.
High-Force End Clamping
Secure heavy workpieces in confined automated cells where the short riveted body saves axial depth, using the male M26x1.5 rod to attach custom clamp arms.
Vertical Lift Positioning
Lift loads up to 200.2 kg with a 2:1 margin and fine-tune the extend endpoint during changeovers, ensuring precise placement without changing cylinder hardware.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X15-20B the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate both neighbors: stepping down to an SDAJ80 yields 2513.3 N push at 0.5 MPa, while this 100 mm bore provides 3927 N. With a safe working load around 2356 N (approximately 60% of the 0.5 MPa push figure) and a vertical lift capacity of roughly 200.2 kg at a 2:1 safety margin, it suits heavy pressing or clamping tasks. Choose this model if your setup requires on-site stroke tuning to perfect a 0-15 mm extend position.
Confirm the bore, 15 mm nominal stroke, 20 mm adjust window, PT3/8 port, and the male M26x1.5 rod thread for your mounting interface. A plain SDAJ does not hold a load when air is lost or the valve is centered; the fixed NBR bumper only decelerates near the end of travel, acting as a mechanical stop rather than a lock. For suspended or vertical loads that must be held without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–15 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 SDAJ100X15-20B FAQ
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, handles speeds of 30-500 mm/s, and functions in temperatures from -20 to +70 C.
The R (M27x2.0) screw mechanically shortens the extend stroke by up to 20 mm, allowing the rod to stop anywhere between 0 and 15 mm. It sets a hard end-stop and does not alter the force output or lock the piston mid-stroke. This SKU has no magnet, so position sensing requires the -S variant for reed or electronic switches.
