About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-40S
The AirTAC SAIJ100X195-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 195 mm travel by up to 40 mm. This creates a precise 155-195 mm usable stroke window for fine-tuning end positions at commissioning without swapping out the cylinder. It delivers robust thrust, pushing with 3927 N and pulling with 3681 N at 0.5 MPa.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. The rear screw acts as a travel stop for position tuning, not a lock, meaning it cannot hold a load without live air. It uses a G1/2 port and retains the standard extruded aluminum barrel with sensor grooves on both sides.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-40S Is Used
Product Size Changeovers
Quickly adjust the 155-195 mm travel window during packaging line format changes to accommodate different carton sizes without adding external mechanical stops.
End-Position Calibration
Fine-tune the retract end position during machine commissioning to dial in exact pressing or forming depths using the rear stopper screw.
Heavy Load Positioning
Move heavy fixtures using the 3927 N push force at 0.5 MPa, relying on the rigid 25 mm SUS304 rod to handle demanding industrial handling tasks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-40S the Right Cylinder?
Choose this 100 mm bore when you need heavy thrust around 3927 N at 0.5 MPa; stepping down to an 80 mm bore drops the push force to 2513 N, while a 125 mm bore increases it to 6136 N. The adjustable stroke is ideal for product-size changeovers on a line, letting you set a new end-stop on the fly instead of machining external stops or buying a fixed-stroke SAI cylinder. For a true drop-in ISO 15552 replacement, match the 100 mm bore, 195 mm stroke, 40 mm adjustment, G1/2 PT ports, SUS304 rod, and the -S magnet.
Because the stroke is 195 mm, you should still evaluate the assembly for side loads, though the 25 mm rod diameter provides solid rigidity. Remember that the rear adjuster only sets the travel end and decelerates the load alongside the air cushions; it does not function as a brake. If your application requires load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder instead. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-40S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 195 mm down to a minimum of 155 mm, giving you a 155-195 mm usable window. The adjuster acts as a mechanical stop to set the end position and does not lock the load without air pressure.
