About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-10
The AirTAC SAIJ160X300-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 10 mm. This creates a precise 290-300 mm usable travel window, enabling exact end-position calibration at commissioning without adding external stops. Built with a robust 40 mm SUS304 stainless steel rod and a PT tapered port, it delivers 10053 N of pull force at 0.5 MPa and reaches a maximum of 2050 kgf at 1.0 MPa.
Because the 300 mm stroke is substantial for this 160 mm bore, the rigid 40 mm rod helps manage side loads, though an external guide is still recommended for unsupported loads. The extruded aluminum barrel includes sensor grooves on both sides, and while this base model lacks a magnet, the design accommodates AirTAC CMSE and DMSE sensors if you later require position detection. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock, so live air is required to hold the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-10 Is Used
Heavy Press Tuning
Dial in the exact 290-300 mm end-stop during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Product Changeover
Adjust the retract position on the fly during automated line changeovers to handle different large-component sizes quickly and accurately.
Fixture Calibration
Fine-tune the travel end during initial fixture setup to prevent over-travel and ensure precise clamping force on 160 mm bore assemblies.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-10 the Right Cylinder?
Select this 160 mm bore adjustable-stroke cylinder when your equipment requires heavy thrust—stepping down to a 125 mm bore drops the 0.5 MPa pull force to 5734 N, while stepping up to a 200 mm bore yields 15080 N. The SAIJ160X300-10 is chosen over a fixed-stroke SAI when you need variable end-stops for product changeovers or fine-tuning during machine setup. It shares the exact ISO 15552 mounting interface and offers a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
For load-holding without continuous air pressure, this cylinder will not suffice because the rear adjuster and air cushions only manage travel ends and deceleration; you would need to look at the SAIL (air-released lock) or BSAI (clamp-lock) series instead. This SKU is configured with a SUS304 stainless steel rod, PT tapered ports, no magnet, and a 10 mm adjustment range.
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 SAIJ160BX300-10 FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. At the maximum operating pressure of 1.0 MPa, it reaches 2050 kgf.
The rear adjuster acts as a stopper that lets you shorten the 300 mm nominal stroke by up to 10 mm, creating a 290-300 mm usable travel window. It sets the travel end and deceleration but does not lock or hold the load without live air pressure.
