About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-30
The AirTAC SAIJ160X190-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust linear motion for heavy-duty applications. It features a 160 mm bore generating 14074 N of push force at 0.7 MPa, alongside a standard PT tapered G3/4 port. By utilizing the integrated 30 mm adjustment screw, this model provides a usable travel window between 160 and 190 mm, allowing technicians to dial in exact retract endpoints without adding external stops.
This extruded aluminum profile cylinder includes sensor grooves on both sides, though this specific SKU is configured without a magnet for electronic or reed switching. The robust 40 mm carbon steel rod and M36x2 thread provide excellent structural integrity and side-load resistance. It relies on standard variable air cushions at both ends for deceleration, while the rear stopper purely acts as a travel limit rather than a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-30 Is Used
Heavy Press Tuning
Provides 14074 N of thrust at 0.7 MPa for heavy pressing operations, with the 30 mm rear adjuster allowing precise bottom-out tuning for different material thicknesses.
Product Changeover
Enables rapid line changeovers by adjusting the retract stroke within the 160-190 mm window, accommodating varying product sizes without replacing the cylinder.
Robotic End Effectors
The 40 mm carbon steel rod handles significant side loads in large robotic grippers, while the ISO 15552 profile ensures straightforward integration into heavy automation frames.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-30 the Right Cylinder?
Selecting the SAIJ160X190-30 is ideal when a machine build requires heavy thrust combined with on-the-fly end-position tuning during commissioning or product changeover. If your application requires slightly less force, stepping down to a 125 mm bore yields 8590 N of push force at 0.5 MPa; however, the 160 mm bore is necessary to reliably sustain the 14074 N output at 0.7 MPa. The adjustable 160-190 mm window prevents the need to swap out a fixed-stroke SAI cylinder when minor dimensional variations exist in a workpiece.
For an exact ISO 15552 replacement, match the 160 mm bore, 190 mm nominal stroke, 30 mm adjustment range, PT G3/4 port, and carbon steel rod. Because this unit lacks a magnet, position sensing is not possible without modification. Furthermore, while the 40 mm rod handles high stresses, any stroke over 300 mm would require external guiding; at 190 mm, the internal rod is sufficiently supported for standard loads. Remember that the rear adjuster only sets the travel end—it does not hold the load without live air, so a SAIL or BSAI lock is required for fail-safe positioning.

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 SAIJ160X190-30 FAQ
At an operating pressure of 0.7 MPa, 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 allows you to shorten the effective stroke by up to 30 mm, creating a usable travel window of 160 to 190 mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
