About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-10S
The AirTAC SAIJ160X50-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end-of-travel position during commissioning. It provides a usable travel window of 40 to 50 mm, trimming the nominal stroke by up to 10 mm without requiring external stops. In the 160 mm bore class, it generates a substantial push force of 14074 N and a pull force of 9425 N at a 0.7 MPa operating pressure.
This variant features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance and pairs with a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-10S Is Used
Heavy Press Tuning
Dial in the exact 40-50 mm travel window during machine setup to accommodate varying material thicknesses in a high-force press without changing hardware.
Product Changeover
Quickly adjust the retract end-stop by up to 10 mm on a packaging line when switching between different product sizes, minimizing downtime.
Corrosive Assembly
Leverage the SUS304 stainless steel rod and 10053 N pull force at 0.5 MPa for heavy assembly tasks in environments requiring high corrosion resistance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-10S the Right Cylinder?
Choose this 160 mm bore adjustable-stroke cylinder when your application demands high thrust but exact end-positioning is not fully fixed until commissioning. If you need less force, stepping down to the 125 mm bore yields 8590 N push at 0.7 MPa; stepping up to the 200 mm bore provides 21991 N. The rear adjuster acts purely as a mechanical stop and works alongside the variable air cushions, but it does not hold the load dynamically without live air pressure. For true load-holding requirements without continuous air, consider the SAIL pneumatic lock or BSAI clamp-lock series.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 50 mm stroke, 10 mm adjustment range, PT port thread, and basic mounting dimensions. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Because the 50 mm stroke is short, side-load stress on the M36x2 rod thread is minimal, though long unsupported strokes still require external guides.

- ✓ 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 SAIJ160BX50-10S FAQ
The rear adjuster is a mechanical stopper that lets you shorten the effective stroke from 50 mm down to 40 mm. This allows you to fine-tune the end position at commissioning, but it is not a lock and requires live air to hold the load.
At an operating pressure of 0.7 MPa, the SAIJ160X50-10-S generates a push force of 14074 N and a pull force of 9425 N. The maximum allowable operating pressure is 1.0 MPa.
