About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-40
The AirTAC SAIJ160X475-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 475 mm travel to a precise 435-475 mm window during commissioning. It delivers heavy thrust, pushing 14074 N at 0.7 MPa, making it well-suited for high-force automation tasks. This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance, paired with PT tapered port threads.
The extruded aluminum barrel includes sensor grooves on both sides, though this unit ships without a magnet for electronic sensing. You can fine-tune the retract end-position via the external stopper screw without swapping out the entire cylinder. Remember that this rear adjuster acts purely as a travel stop to set deceleration limits; it does not hold the load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-40 Is Used
Heavy Press Tuning
Dial in the exact 435-475 mm end-stop during machine setup to prevent over-travel when stamping or pressing heavy components.
Product Size Changeover
Quickly adjust the retract position on a packaging line to handle different pallet heights without swapping out the actuator.
High-Force Positioning
Leverage the 14074 N push force at 0.7 MPa to shift heavy industrial jigs into place, using the rear screw for final alignment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-40 the Right Cylinder?
Selecting this 160 mm bore over a smaller 125 mm option jumps the 0.5 MPa push force from 6136 N up to 10053 N, giving you a substantial power upgrade for heavy molds or pressing operations. An adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops to accommodate product-size changes on a line without bolting on external stops. For load-holding requirements without live pressure, this standard adjuster will not act as a brake; you should instead look at the SAIL or BSAI series.
When ordering for an ISO 15552 replacement, verify the 475 mm stroke, 40 mm adjustment range, PT G3/4 port, and SUS304 rod material. Because the 475 mm stroke is long, the 40 mm diameter rod and M36x2 thread can handle significant side loads, but an external guide is still recommended to prevent rod binding. Mounting options are limited to the SAIJ subset: 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 SAIJ160 Adjustable Cylinder SAIJ160BX475-40 FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder produces a push force of 14074 N and a pull force of 9425 N. It can deliver up to 18095 N push force at 0.9 MPa.
The rear adjuster screw lets you shorten the effective travel from the nominal 475 mm down to a minimum of 435 mm. It functions as a mechanical stop to fine-tune the end position, but it is not a lock and will not hold the load without live air.
