About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-20
The AirTAC SAIJ160X150-20 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a robust 10053N push force at 0.5MPa and uses a PT tapered G3/4 port. The built-in adjustment screw allows you to trim the effective travel back by up to 20mm, creating a precise 130-150mm usable stroke window for exact end-position tuning.
This model features a 40mm carbon steel rod and an M36x2 thread, offering high rigidity for heavy loads. It includes variable air cushions at both ends to manage kinetic energy, but the rear adjuster acts only as a travel stop. It does not hold the load without live air pressure, so applications requiring true load-holding without compressed air should use an SAIL lock or BSAI clamp-lock cylinder instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-20 Is Used
Heavy Fixture Positioning
Dial in the exact 130-150mm travel during heavy fixture commissioning to guarantee precise alignment without adding external stopper blocks.
Product Size Changeover
Quickly adapt the cylinder's end-stop on packaging lines handling varying product sizes by adjusting the rear screw up to 20mm.
Press Fit Tuning
Fine-tune the pressing depth on heavy assembly equipment by trimming the stroke in milliseconds, ensuring perfect contact force.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-20 the Right Cylinder?
Choose this 160mm bore when you need substantial thrust—10053N push and 9425N pull at 0.5MPa—for heavy fixtures, stepping down from a 200mm bore (15708N at 0.5MPa) to save space, or stepping up from a 125mm bore (6136N at 0.5MPa) for higher force demands. The adjustable stroke is ideal for machine setups requiring variable end-stops or fine-tuning during commissioning without swapping out the entire cylinder.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard bore, stroke, and port footprints. Configuration for this SKU includes a 150mm stroke, 20mm adjustment range, PT port threads, and no magnet. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

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 SAIJ160X150-20 FAQ
At a 0.5MPa operating pressure, this 160mm bore cylinder generates a push force of 10053N and a pull force of 9425N. At the maximum 1.0MPa pressure, it can deliver up to 2050 kgf.
The rear adjuster screw allows you to shorten the 150mm nominal stroke by up to 20mm, providing an effective travel window of 130-150mm. This stopper only sets the end position and deceleration; it does not lock the load without continuous air pressure.
