About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-40S
The AirTAC SAIJ160X135-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, designed to fine-tune end positions without external stops. It provides a usable travel window of 95-135 mm, allowing you to dial back the 135 mm nominal stroke by up to 40 mm during commissioning. Equipped with a -S magnet, it supports CMSE reed and DMSE solid-state sensors housed within the dual-side extruded aluminum barrel grooves. Delivering massive thrust, it outputs 14074N push and 9425N pull at 0.7 MPa operating pressure.
This heavy-duty unit features a 40 mm carbon steel rod with an M36x2 thread, engineered to handle substantial side loads and secure large tooling. The rear adjustment screw acts purely as a travel stop to set deceleration and end-of-stroke positioning; it does not hold the load without live air. For pneumatic load-holding requirements without continuous pressure, an external rod lock or related AirTAC SAIL series is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-40S Is Used
Heavy Press Tuning
Fine-tune the pressing depth of large industrial assemblies by dialing in the 40 mm rear stopper, ensuring perfect component mating without repositioning the entire cylinder.
Product Size Changeover
Adapt automated packaging lines to different carton sizes by adjusting the 135 mm stroke down to 95 mm, allowing rapid format changes without mechanical rebuilds.
Variable End Stops
Set precise retraction limits on heavy material handling gates, using the rear stopper to define exact open positions while relying on the 40 mm rod for structural stability.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-40S the Right Cylinder?
Select this 160 mm bore cylinder when your application demands high force—stepping down to a 125 mm bore yields just 8590N push at 0.5 MPa, whereas this SAIJ160X135-40-S provides 10053N at the same pressure. The 40 mm adjustment range is ideal for machinery requiring precise variable end-stops during product changeovers, avoiding the need to physically swap cylinders for slight length differences. Because the nominal stroke is 135 mm, an external guide is not strictly mandated for side loads, but the robust 40 mm rod and M36x2 thread provide excellent rigidity for heavy off-center loads.
Ensure your setup matches the exact configuration: a 160 mm bore, 135 mm nominal stroke, 40 mm rear adjustment, PT tapered G3/4 port, and a -S magnet for position sensing. It is dimensionally interchangeable per ISO 15552 standards and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the variable air cushions at both ends and the rear adjuster only manage travel ends; they will not brake or hold a suspended load mechanically.

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 SAIJ160X135-40S FAQ
At 0.9 MPa, this cylinder provides a push force of 18095N and a pull force of 9425N. The maximum push force reaches 2050 kgf at 1.0 MPa. The operational speed range for this 160 mm bore is 30-500 mm/s.
The rear adjuster screw allows you to shorten the effective travel from the 135 mm nominal stroke down to 95 mm. This mechanical stop sets the retract end position for fine-tuning during setup but does not lock or hold the load without continuous air pressure.
