About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX60-50
The AirTAC SAIJ40X60-50 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 60 mm stroke with an adjustment range of 50 mm, yielding a highly versatile usable travel window of 10 to 60 mm. Delivering 628 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads.
This adjustable-stroke design allows you to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop to set the end position and does not lock or hold the load without live air pressure. It supports a subset of mounting options including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX60-50 Is Used
Machine Setup & Changeover
Dial in the exact retract position during commissioning or product changeover without machining new external stopper blocks.
Variable End-Stop Forming
Accommodate multiple material lengths on a single fixture by adjusting the 10 to 60 mm travel window on the fly.
Actuator Position Tuning
Trim the effective stroke back by up to 50 mm to perfectly time a delicate pressing or indexing operation.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX60-50 the Right Cylinder?
Choose this 40 mm bore cylinder when an application requires precise end-position tuning across a 10 to 60 mm window, stepping down from a 50 mm bore that offers 982 N push force at 0.5 MPa if your force needs are lower. An adjustable stroke is ideal for product changeovers on a line, letting you dial in the exact travel without installing a fixed-stroke SAI cylinder. Since the stroke is under 300 mm, side-load concerns are minimal, though the 16 mm rod and M12x1.25 thread handle standard loads well. For load-holding without live air, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock. To match this ISO 15552 replacement, verify the 40 mm bore, 60 mm stroke, 50 mm adjustment, PT port, SUS304 rod, and no magnet.
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 SAIJ40BX60-50 FAQ
At 0.5 MPa operating pressure, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. It can reach up to 1130 N push force at 0.9 MPa.
The SAIJ40X60-50 has a nominal 60 mm stroke with a 50 mm adjustment range, creating a usable travel window of 10 to 60 mm. A rear screw acts as a stop to shorten the stroke, but it is not a lock and will not hold the load without live air pressure.
