About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-50S
The AirTAC SAIJ160X200-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 150-200 mm usable travel window from the 200 mm nominal stroke. Delivering 14074 N of pull force at 0.7 MPa, it is built with a robust 40 mm SUS304 stainless steel rod and a PT tapered G3/4 port. This configuration provides excellent corrosion resistance and is equipped with a magnet for CMSE or DMSE sensors.
The external adjusting screw allows you to fine-tune the retract end position at commissioning without adding external stops or swapping the cylinder. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts as a travel stop and deceleration aid, not a lock; it will not hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-50S Is Used
Product Changeover
Dial in the 150-200 mm travel window during format changes to accommodate different package sizes without swapping hardware.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to dial out mechanical play and hit exact positioning.
Heavy Assembly Pressing
Leverage the 14074 N pull force at 0.7 MPa to seat heavy components, using the rear stop to prevent over-travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-50S the Right Cylinder?
Choose this 160 mm bore when an 80 mm cylinder's 3518 N push force at 0.7 MPa is insufficient, but a 200 mm bore delivering 21991 N would be excessive. The 50 mm adjustment range is ideal for production lines needing variable end-stops for different product sizes without changing the physical cylinder. For load-holding without live air pressure, select the SAIL or BSAI series instead, as the SAIJ adjuster is strictly a stop.
To replace an ISO 15552 cylinder, match the 160 mm bore, 200 mm stroke, 50 mm adjustment, G3/4 PT ports, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is 200 mm, side-load is moderate, but for maximum life, ensure the load is guided externally to protect the 40 mm rod thread from bending moments.
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 SAIJ160BX200-50S FAQ
The rear adjuster allows you to shorten the 200 mm nominal stroke by up to 50 mm, providing a usable travel window of 150-200 mm. It acts as a mechanical stop to set the end position and does not lock the load without live air.
At 0.7 MPa operating pressure, the SAIJ160X200-50-S provides 14074 N of pull force and 14074 N of push force. It can deliver up to 18095 N of push force at 0.9 MPa.
