About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-100S
The AirTAC SAIJ40X600-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a 500-600 mm usable travel window, allowing you to dial back the 600 mm nominal stroke by up to 100 mm during commissioning. Delivering 628 N of push force at 0.5 MPa, it uses a PT tapered G1/4 port and a 16 mm rod with an M12x1.25 thread.
This SKU is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet for CMSE or DMSE sensors. The extruded aluminum barrel omits the FB, CA, CB, and CR mounts, supporting only the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting interfaces. Because the rear adjuster and air cushions only decelerate the moving piston, this cylinder cannot hold a load without live air pressure; use a SAIL or BSAI series cylinder if fail-safe load holding is required.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-100S Is Used
Variable End-Stop Tuning
Dial in the exact retract position from 500 to 600 mm during machine setup, eliminating the need to machine custom spacer blocks for every new product run.
Product Changeover Lines
Quickly adapt the stroke window on packaging conveyors when handling different carton sizes, using the 100 mm adjustment range to alter the retract distance on the fly.
Corrosive Assembly Stations
Leverage the SUS304 stainless steel rod and 628 N push force in light-duty assembly cells where moisture or washdowns would quickly degrade standard carbon steel rods.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-100S the Right Cylinder?
Choose this 40 mm bore when an application demands 628 N push or 528 N pull at 0.5 MPa, bridging the gap between the 32 mm (402 N) and 50 mm (982 N) sizes. An adjustable stroke is preferred over a fixed SAI cylinder when you need to fine-tune the retract end-position on the fly without adding external stops or swapping the cylinder body during product changeovers.
When replacing an ISO 15552 cylinder, match the 40 mm bore, 600 mm stroke, 100 mm adjustment range, PT G1/4 port, and -S magnet. Because the 600 mm stroke is long, the 16 mm rod will experience amplified deflection under side loads; always guide the load externally to prevent premature seal wear. The rear screw is a travel stop, not a locking brake, so maintain live air for positioning.
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 SAIJ40 Adjustable Cylinder SAIJ40BX600-100S FAQ
At 0.5 MPa operating pressure, this 40 mm bore cylinder generates 628 N of push force and 528 N of pull force. It can reach 1130 N of push force if operated at the maximum 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 600 mm nominal stroke down to 500 mm. This provides a 500-600 mm usable window for fine-tuning the end position without replacing the cylinder.
