About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-40S
The AirTAC SAIJ160X200-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 200 mm nominal stroke that can be fine-tuned down by up to 40 mm, giving you a precise 160-200 mm usable travel window during commissioning. Built to handle heavy loads, it delivers 14074 N of push force at 0.7 MPa and features a robust 40 mm piston rod with an M36x2 thread.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE / DMSE sensor integration. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear stopper allows you to set the end position without adding external stops. The adjuster acts purely as a travel stop, so you must maintain live air to hold the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-40S Is Used
Heavy Press Tuning
Dial in the exact 160-200 mm end position for heavy pressing tasks without machining new hard stops.
Product Changeover
Quickly adjust the stroke by up to 40 mm on a packaging line when switching to different product sizes.
Robotic End Effectors
Uses the SUS304 rod and CMSE / DMSE sensors for reliable position feedback in washdown assembly areas.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-40S the Right Cylinder?
Select this 160 mm bore when a 100 mm bore (providing 5497 N push at 0.7 MPa) is insufficient, but a 200 mm bore (21991 N) would be excessive. An adjustable stroke is ideal for machinery that requires variable end-stops or frequent product changeovers, allowing you to trim the travel back by up to 40 mm without swapping the cylinder. To replace an ISO 15552 cylinder, match the 160 mm bore, 200 mm stroke, PT G3/4 port, and the -S magnet requirement.
Because the 200 mm stroke is relatively short for this large bore, side-load stress is minimal, but the heavy 40 mm rod still requires proper alignment. If your application demands true load-holding without continuous air pressure, the rear adjuster here is not a lock; you should look at the SAIL or BSAI series instead. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX200-40S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 200 mm nominal stroke by up to 40 mm, creating a 160-200 mm travel window. It only sets the end position and does not lock the load without live air pressure.
