About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-50S
The AirTAC SAIJ160X500-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 500 mm travel to a precise 450-500 mm window during commissioning. Delivering massive thrust, it provides 14074 N push force at 0.7 MPa and reaches 18095 N at 0.9 MPa. This bore size uses a G3/4 port and a 50 mm cushion length to manage heavy kinetic energy smoothly.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The rear stopper sets the end-of-travel deceleration point but does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-50S Is Used
Heavy Press Tuning
Fine-tune the 450-500 mm travel window on heavy stamping or pressing lines to accommodate different die heights without mechanical modifications.
Pallet Positioning
Adjust the rear stopper on the fly to handle varying pallet sizes on a high-thrust conveyor transfer system, ensuring exact end-of-line placement.
Machine Changeover
Rapidly reset the end-stop position during product family changeovers on large automated machinery, leveraging the 50 mm adjustment range.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-50S the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires the 10053 N pull force at 0.5 MPa that smaller 125 mm bores cannot provide, while stepping up to a 200 mm bore would be excessive. The 50 mm adjustment range is ideal for fine-tuning end positions on product changeovers without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, this standard adjuster will not suffice; consider an AirTAC SAIL or BSAI cylinder instead.
Because the 500 mm stroke is substantial, the 40 mm diameter SUS304 rod will still experience side-loading forces if the load is unsupported. An external guide rail is strongly recommended to prevent rod binding and premature seal wear. This ISO 15552 dimensionally interchangeable profile cylinder uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and PT tapered ports.
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 SAIJ160BX500-50S FAQ
At an operating pressure of 0.5 MPa, this 160 mm bore cylinder generates 10053 N of pull force and 14074 N of push force at 0.7 MPa. The maximum push force reaches 18095 N at 0.9 MPa.
The rear external adjusting screw acts as a mechanical stopper that can shorten the effective stroke by up to 50 mm, providing a usable travel window of 450 to 500 mm. It allows precise end-position tuning at commissioning without changing the cylinder itself.
