About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-50
The AirTAC SAIJ160X185-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 135 to 185 mm, allowing you to dial back the piston's retract end-position by up to 50 mm during commissioning. Belonging to the 160 mm bore class, it delivers substantial thrust, generating 10053 N of pull force at a 0.5 MPa operating pressure.
This extruded aluminum barrel design incorporates sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. The standard carbon steel rod utilizes an M36x2 thread, and pneumatic connections use PT tapered G3/4 ports. The adjustable stopper functions strictly as a travel limit, working alongside the 50 mm air cushions to manage end-of-stroke deceleration.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-50 Is Used
Heavy Machinery Setup
Provides a 135-185 mm travel window to precisely set retract positions during initial equipment commissioning without machining new stopper blocks.
Product Line Changeover
Allows operators to quickly dial back the stroke by up to 50 mm when accommodating a new product size on the manufacturing line.
High-Force Clamping
Delivers 10053 N of pull force at 0.5 MPa for secure clamping, with a 50 mm air cushion to smoothly decelerate the heavy 160 mm piston.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-50 the Right Cylinder?
Choose this 160 mm bore when an application requires high force (10053 N pull at 0.5 MPa) alongside a variable end-stop. If your setup needs less force, stepping down to a 125 mm bore yields 5734 N pull, whereas a 200 mm bore provides 15080 N pull. The 50 mm adjustment range is ideal for product-size changeovers, letting you fine-tune the retract position without swapping the cylinder or adding external stops. For load-holding without live air pressure, note that this adjuster is only a stop; you would need an external rod lock or a SAIL/BSAI series cylinder.
As a dimensionally interchangeable ISO 15552 cylinder, this model matches standard mounting footprints using a reduced set of accessories: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the 185 mm stroke is relatively short for this bore, side-load concerns are minimal, but an external guide is still recommended for heavy offset loads.
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 SAIJ160X185-50 FAQ
It features a rear adjusting screw that acts as a mechanical stop, letting you shorten the effective stroke from 185 mm down to 135 mm. This creates a 50 mm adjustable travel window for fine-tuning the retract end-position at commissioning.
At a 0.5 MPa operating pressure, it provides 14074 N of push force and 10053 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 18095 N.
