About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-50S
The AirTAC SAIJ160X135-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers substantial thrust, offering 10053N of pull force and 14074N of push force at 0.7 MPa. By incorporating a 50mm adjustment mechanism, this SKU provides a usable travel window of 85 to 135mm, allowing precise end-position tuning during commissioning without external stops.
This -S variant includes a magnet for position detection and uses a standard carbon steel rod with an M36x2 thread. It operates at speeds of 30-500mm/s and features a G3/4 PT tapered port. The extruded aluminum barrel includes sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for flexible mounting.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-50S Is Used
Heavy-Duty Press Tuning
Dial in the exact 85-135mm retract stop during press setup to accommodate varying material thicknesses without swapping cylinders.
Machine Changeover
Quickly adjust the end-of-stroke position on automated lines when switching between different product sizes and formats.
Assembly Station Setup
Fine-tune the actuation depth at commissioning to prevent damage to heavy components, ensuring precise and repeatable operations.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-50S the Right Cylinder?
Choose this 160mm bore when an 80mm bore (2268N pull at 0.5MPa) lacks the force for heavy positioning, but a 200mm bore is unnecessary. The 50mm rear adjuster acts purely as a mechanical stop to fine-tune the retract distance within that 85-135mm range during machine changeover; it does not lock or hold the load without live air. For fail-safe load holding, consider the SAIL or BSAI series instead. To match this ISO 15552 footprint, specify the 160mm bore, 135mm stroke, 50mm adjust, G3/4 PT port, and -S magnet.
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 SAIJ160X135-50S FAQ
At 0.5 MPa, it provides 10053N of pull force and 14074N of push force at 0.7 MPa. The maximum push force is 18095N at 0.9 MPa.
The rear adjuster allows you to shorten the 135mm nominal stroke by up to 50mm, creating an adjustable travel window of 85 to 135mm. It functions as a travel stop and does not lock the load without live air pressure.
