About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-50S
The AirTAC SAIJ160X475-50-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 425 to 475 mm, allowing you to dial back the 475 mm nominal stroke by up to 50 mm during commissioning. It delivers a robust 10053 N pull force at 0.5 MPa, making it suitable for moving heavy loads.
This unit includes a SUS304 stainless steel rod and a built-in magnet for CMSE reed and DMSE electronic sensors. It uses PT tapered ports (G3/4) and relies on variable air cushions at both ends to decelerate the payload. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for dead-air holding, use a SAIL or BSAI series cylinder.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-50S Is Used
Heavy Press Tuning
Dial in the exact 425-475 mm end-stop during press setup to accommodate varying material thicknesses without swapping actuators.
Product Changeover
Quickly adjust the retract position on packaging lines when transitioning to different pallet or product sizes.
Machine Commissioning
Fine-tune the final end-of-travel position during initial machine build to avoid machining custom external stoppers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-50S the Right Cylinder?
Choose this adjustable-stroke model when you need fine end-position tuning on a 475 mm stroke without adding external stopper blocks. If your application requires less force, stepping down to a 125 mm bore yields 5734 N of pull at 0.5 MPa. Because the 475 mm stroke creates a long lever arm, an external guide is recommended to prevent excessive side-loading on the 40 mm rod. To match this ISO 15552 cylinder, specify the 160 mm bore, 475 mm stroke, 50 mm adjustment, PT ports, SUS304 (B) rod, and the -S magnet option.
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 SAIJ160 Adjustable Cylinder SAIJ160BX475-50S FAQ
At 0.5 MPa, it provides 10053 N of pull force and 14074 N of push force. The operating speed range for this 160 mm bore cylinder is 30-500 mm/s.
A rear screw stopper lets you shorten the 475 mm nominal stroke by up to 50 mm, creating a 425-475 mm travel window. This stopper only sets the end position; it does not lock the load without live air pressure.
