About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-40S
The AirTAC SAIJ160X650-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 610 to 650 mm, allowing you to dial back the nominal stroke by up to 40 mm during commissioning without adding external stops. Delivering 14074 N of push force at 0.7 MPa, it handles heavy-duty positioning.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a magnetic piston for CMSE or DMSE sensors. The PT tapered ports ensure tight pneumatic connections. Because the 650 mm stroke is long, the 40 mm diameter rod requires an external guide to prevent excessive side loading and premature seal wear.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-40S Is Used
Heavy Press Tuning
Fine-tune the exact pressing depth of heavy industrial assemblies on the fly without swapping out the entire actuator.
Product Changeover
Adjust the retract end position by up to 40 mm to accommodate different product lengths running on the same line.
Long-Stroke Positioning
Move substantial loads across a 610 to 650 mm travel range while relying on the rear stop to set the final resting position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-40S the Right Cylinder?
Select this 160 mm bore cylinder when your application requires high thrust (up to 18095 N at 0.9 MPa) and precise variable end stops. If you need less force, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa. Choose the SAIJ adjustable design over a fixed SAI when you need fine end-position tuning for product changeovers.
The rear adjuster acts purely as a travel stop, not a lock. It cannot hold a load without live air pressure; for true load-holding, use an external rod lock or pilot-operated check valve. This ISO 15552 dimensionally interchangeable cylinder uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160BX650-40S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 40 mm, providing a usable travel window of 610 to 650 mm. It acts as a mechanical stop to fine-tune the retract position and is not a lock.
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 18095 N of push force.
