About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-50S
The AirTAC SAIJ160X170-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 120 to 170 mm, allowing you to dial back the nominal 170 mm stroke by up to 50 mm during commissioning. This bore generates a substantial 14074 N push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks.
Equipped with a PT tapered port and a standard carbon steel rod, this unit integrates an -S magnet for position sensing. It works seamlessly with AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-50S Is Used
Heavy Material Positioning
Dial in the exact 120-170 mm travel needed to seat heavy steel or composite components precisely during assembly machine setup.
Product Size Changeovers
Quickly adjust the retract stop to accommodate different product lengths on a single production line without changing cylinders.
Variable End-Stop Actuation
Use the rear mechanical stop to fine-tune the end position on automated machinery, ensuring repeatable heavy-duty strokes.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X170-50S the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore (delivering 5497 N push at 0.7 MPa) is insufficient for your heavy load requirements. An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops for product changeovers without swapping the physical cylinder or adding external stops. For load-holding without continuous air pressure, this cylinder is insufficient as the adjuster is only a stop; you should consider an SAIL air-released lock or BSAI clamp-lock cylinder instead.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 170 mm stroke, 50 mm adjustment, PT port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR brackets. With a 170 mm stroke, side-load is moderate, but always ensure proper external guiding for heavy loads. The robust 40 mm rod and M36x2 thread handle high side loads effectively.
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 SAIJ160X170-50S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. It can deliver a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw lets you shorten the effective travel from the nominal 170 mm down to 120 mm, creating a 120-170 mm usable window. This allows fine-tuning of the retract end position at commissioning without external stops.
