About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-10S
The AirTAC SAIJ160X275-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a 10 mm trim. This yields a usable travel window of 265 to 275 mm, allowing precise end-position tuning at commissioning without swapping hardware. It delivers a robust 10053 N push force at 0.5 MPa and utilizes a SUS304 stainless steel rod for superior corrosion resistance.
Fitted with PT tapered ports and a -S magnet for CMSE or DMSE sensors, this 160 mm bore unit runs at 30 to 500 mm/s. The rear adjuster acts purely as a travel stop to set deceleration, meaning it will not hold a load without live air pressure. For secure load-holding, an external SAIL or BSAI locking cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-10S Is Used
Press Fit Tuning
Dial in the exact 265-275 mm insertion depth during machine setup to accommodate varying part tolerances without changing the cylinder.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm when switching production lines to different package sizes, avoiding external stop modifications.
Heavy Material Handling
Leverage the 10053 N push force to move heavy workpieces while fine-tuning the end-of-stroke deceleration point for smooth stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-10S the Right Cylinder?
Choose this 160 mm bore when an application demands high thrust (10053 N push at 0.5 MPa) but requires a 10 mm setup buffer for product changeovers. If you need less force, stepping down to a 125 mm bore yields 6136 N; stepping up to a 200 mm bore provides 15708 N. The adjustable stroke is ideal for dialing in final positions, whereas a fixed-stroke SAI cylinder lacks this commissioning flexibility.
Ensure your ISO 15552 replacement matches these exact parameters: 160 mm bore, 275 mm stroke, 10 mm adjustment, PT ports, SUS304 (B) rod, and a -S magnet. Because the 275 mm stroke is relatively long for this large bore, always use an external guide to prevent excessive side-loading on the rod.
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 SAIJ160BX275-10S FAQ
It provides 10053 N of push force and 9425 N of pull force at 0.5 MPa. The rear adjuster is a travel stop, not a lock; it will not hold the load without continuous air pressure. For true load-holding, use an SAIL or BSAI cylinder.
The nominal stroke is 275 mm, and the -10 adjustment code allows you to shorten the effective travel by up to 10 mm. This creates a usable adjustable travel window of 265 to 275 mm for precise end-position tuning.
