About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-75B
The AirTAC SDAJ100X75-75B is a double-acting compact cylinder featuring an external R (M27x2.0) adjuster screw that dials the extend stop between 0 and 75 mm. Because the adjuster 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. The short riveted body drastically reduces axial mounting depth compared to conventional round-body units, fitting into tight machine footprints.
This specific SKU includes a male-threaded M26x1.5 piston rod and uses a PT3/8 air port. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this base configuration lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S variant.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 75 mm |
| Adjustable range | 0 – 75 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 75 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 SDAJ100X75-75B Is Used
Heavy Press Fitment
Dial in the exact 0-75 mm extend stop on heavy press operations to seat bearings without over-travel, leveraging the 3927 N push force.
Automated Forming Lines
Adjust the mechanical stop on-site during product changeovers to accommodate varying material thicknesses while maintaining a compact machine footprint.
Vertical Lifting Jigs
Lift loads up to 200.2 kg safely with a 2:1 margin, using the male M26x1.5 rod for rigid mounting and tuning the extend position to prevent crashes.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-75B the Right Cylinder?
When sizing this unit, evaluate both neighbours: stepping down to the SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. The computed safe working load is approximately 2356 N, which equates to a vertical lift capacity of about 200.2 kg when applying a 2:1 safety margin. Choose this model if your fixture requires heavy push force combined with on-site stroke tuning during changeovers.
Confirm the 100 mm bore, 75 mm maximum stroke, 75 mm adjustment window, and PT3/8 porting match your pneumatic layout. The male M26x1.5 rod end requires a matching female interface to avoid side load. Remember that a plain SDAJ does not hold position or load upon air loss or valve centring; the fixed NBR bumper only decelerates the stroke end and the R screw acts as a mechanical stop, not a lock. For secure load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–75 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 SDAJ100X75-75B FAQ
This 100 mm bore double-acting cylinder provides 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 of 801 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, speed is 30-500 mm/s, and the air port is PT3/8.
The M27x2.0 R screw shortens the extend stop by up to 75 mm without shims or part changes, yielding a usable extend range of 0-75 mm. This screw is strictly a mechanical stop, not a mid-stroke lock; the cylinder will drift if air is lost. Also, this non-S SKU lacks a piston magnet and cannot take reed or electronic switches.
