About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-75S
The AirTAC SAIJ160X600-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 525 to 600 mm. It delivers a robust 14074 N of push force at 0.7 MPa and features a stainless steel SUS304 rod for superior corrosion resistance. The barrel incorporates sensor grooves on both sides, and because this is an -S variant, it includes a magnet for use with CMSE reed and DMSE electronic solid-state switches.
This model utilizes a PT tapered G3/4 port and relies on adjustable air cushions at both ends to decelerate the load. The rear adjuster functions strictly as a mechanical stop to fine-tune the end position during commissioning without requiring external stops. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-75S Is Used
Variable Stroke Conveying
Dial back the travel from 600 mm to 525 mm to accommodate different package sizes on a heavy-duty conveyor line without physically swapping the actuator.
Heavy Press Tuning
Fine-tune the exact end-position of a 14074 N pressing operation during commissioning, ensuring precise contact without adding bulky external mechanical stops.
Machine Changeover
Rapidly adjust the rear stopper for product changeovers, setting the exact stroke window required for new component feeding or clamping stations.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-75S the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires heavy thrust up to 14074 N combined with a variable end-stop. If the force is excessive, stepping down to a 100 mm bore yields 5497 N of push force at 0.5 MPa. Conversely, if more power is needed, the 200 mm bore provides 21991 N at 0.7 MPa. An adjustable stroke is selected over a fixed SAI cylinder when machine setups demand fine end-position tuning or frequent product-size changeovers.
Because the nominal stroke is 600 mm, the 40 mm diameter rod and M36x2 thread will experience significant leverage forces; an external guide is recommended to prevent side-loading damage. The rear adjuster and air cushions only set travel limits and deceleration, so they cannot hold the load without live air pressure. For true load-holding without continuous pressure, specify an SAIL air-released lock, a BSAI clamp-lock, or an external rod lock. To match this ISO 15552 replacement, use a 160 mm bore, 600 mm stroke, 75 mm adjustment, PT G3/4 port, the specified mounting subset, and a -S magnet.

- ✓ 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 SAIJ160BX600-75S FAQ
At 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. The maximum allowable operating pressure is 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel from the 600 mm nominal stroke down to 525 mm. It sets the end position but does not lock the load without live air pressure.
