About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-30
The AirTAC SAIJ160X500-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel back by up to 30 mm. This creates a 470-500 mm usable window, allowing you to dial in the exact retract position at commissioning without adding external stops. It delivers massive thrust, pushing 18095 N at 0.9 MPa and pulling 9425 N at 0.5 MPa.
Built with a SUS304 stainless steel rod and PT tapered ports, this unit handles heavy loads while resisting corrosion. The extruded aluminum barrel includes sensor grooves on both sides, and the variable air cushions at both ends absorb the impact of this large bore's moving mass. The rear adjuster acts purely as a travel stop for deceleration, not a lock, so live air is required to hold the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-30 Is Used
Heavy Pressing Operations
Provides up to 18095 N of adjustable-force pressing, using the 470-500 mm travel window to accommodate varying material thicknesses during machine setup.
Product Changeover Systems
Fine-tune the retract end-stop on the fly when switching production runs, avoiding the need to physically swap out long-stroke cylinders for different part sizes.
Large Assembly Jigs
Handles heavy fixture positioning on automated lines, relying on the 40 mm SUS304 rod to withstand industrial side loads while the rear stopper sets the final rest position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-30 the Right Cylinder?
Choose this 160 mm bore when 10053 N of push force at 0.5 MPa is insufficient, but stepping up to the 200 mm bore (15708 N at 0.5 MPa) would be overkill. The adjustable 470-500 mm stroke is ideal for product changeovers on a line where the exact end position varies slightly, saving you from swapping out a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, you must look to the SAIL or BSAI series, as the SAIJ adjuster only sets the travel end. Because this is a 500 mm stroke, the 40 mm rod and M36x2 thread carry significant side-load capacity, but an external guide is still recommended for the unsupported length. ISO 15552 mounting options include 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 SAIJ160BX500-30 FAQ
At 0.9 MPa, the push force is 18095 N and the pull force is 14074 N. At 0.5 MPa, it delivers 10053 N push and 9425 N pull.
The rear adjuster acts as an external stopper that shortens the 500 mm nominal stroke by up to 30 mm, giving a usable travel window of 470-500 mm. It only sets the end position and does not lock the load without live air pressure.
