About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-30
The AirTAC SAIJ160X150-30 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. Equipped with a rear adjusting screw, this model allows you to trim the effective stroke by up to 30 mm, providing a usable travel window of 120 to 150 mm without swapping the cylinder or adding external stops. It delivers substantial thrust, generating 10053 N of push force and 9425 N of pull force at 0.5 MPa.
Featuring a robust 40 mm carbon steel rod and an M36x2 rod thread, this bore size is built to withstand demanding industrial environments. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing for straightforward integration of CMSE or DMSE position sensors if a magnet is specified later. Standard variable air cushions at both ends manage deceleration, while the rear stopper handles the precise end-position setting.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-30 Is Used
Variable Pressing Depth
Dial in the exact 120 to 150 mm travel window during machine setup to accommodate material thickness variations without reprogramming the motion controller.
Product Size Changeovers
Quickly adjust the retract end-stop on a packaging line to handle different carton sizes, utilizing the 30 mm trim range to switch formats rapidly.
Heavy-Duty End Tuning
Fine-tune the final resting position of heavy clamping fixtures at commissioning, leveraging the 9425 N pull force to secure large workpieces.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-30 the Right Cylinder?
Selecting this 160 mm bore cylinder is ideal when an application demands high force alongside a variable end-stop, such as pressing or clamping stations that undergo frequent product changeovers. If the full 10053 N push force at 0.5 MPa exceeds your requirements, stepping down to a 125 mm bore yields 6136 N, whereas moving up to a 200 mm bore provides 15708 N. The PT tapered port thread and G3/4 port size ensure high flow capacity for the 30-500 mm/s speed range typical of this large bore.
Because this is an adjustable-stroke model, the rear screw acts purely as a travel stop and does not lock the load without live air pressure; for fail-safe load holding, consider an AirTAC SAIL or BSAI variant. To achieve a true ISO 15552 replacement, match the 160 mm bore, 150 mm nominal stroke, 30 mm adjustment, PT port thread, and your required mounting accessory from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Although the stroke is under 300 mm, the heavy 40 mm rod still requires adequate external guiding to prevent excessive side-loading on the barrel seals.
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 SAIJ160X150-30 FAQ
At a standard operating pressure of 0.5 MPa, this double-acting cylinder provides a push force of 10053 N and a pull force of 9425 N. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 150 mm nominal stroke by up to 30 mm, creating a usable travel window of 120 to 150 mm. This allows for fine end-position tuning at commissioning without adding external stops.
