About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-100S
The AirTAC SAIJ100X600-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 500-600 mm usable travel window. It delivers a robust 3927 N push force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. The barrel utilizes an extruded aluminum profile with sensor grooves on both sides, and because this unit includes a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-travel detection.
This specific SKU is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance and PT tapered port threads. The rear adjuster functions strictly as a mechanical stop to fine-tune the retract position during commissioning; it does not lock the load. For applications requiring position holding without live air pressure, consider the SAIL pneumatic-lock or BSAI clamp-lock variants.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-100S Is Used
Variable End-Stop Machining
Dial in the exact 500-600 mm retract position for machining fixtures without manufacturing custom spacers or swapping cylinders.
Product Changeover Diverter
Quickly adjust the stroke window on a packaging line diverter to accommodate different carton sizes on the fly.
Heavy-Duty Press Setup
Leverage the 3927 N push force to seat heavy components, using the rear stop to fine-tune the final pressing depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-100S the Right Cylinder?
Selecting this 100 mm bore over a smaller 80 mm variant steps the thrust up from 2513 N to 3927 N at 0.5 MPa, providing the extra force needed for high-inertia loads. The 100 mm adjustment range is ideal for product changeovers on automated lines, allowing operators to dial in the exact end-stop without swapping the cylinder or adding external stops. When matching an ISO 15552 replacement, verify the 600 mm stroke, 100 mm adjustment, PT port threads, and the -S magnet.
Because the stroke is 600 mm, the M20x1.5 piston rod is highly susceptible to side-loading and sagging. An external guide rail system must be used to prevent premature seal wear and binding. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 configurations, deliberately omitting the FB, CA, CB, and CR styles.
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 SAIJ100BX600-100S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 600 mm down to 500 mm. It is designed for fine-tuning end positions at commissioning and does not hold the load without continuous live air pressure.
