About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-75
The AirTAC SAIJ160X135-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position during commissioning. Based on a 135 mm nominal stroke and a 75 mm adjustment code, it provides a usable travel window of 60-135 mm without requiring external stops. In this 160 mm bore class, the carbon steel rod is a robust 40 mm with an M36x2 thread, delivering 10053 N of pull force at 0.5 MPa.
The external adjuster acts purely as a mechanical stop to set the retract end position and relies on the variable air cushion for deceleration; it does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series. This extruded aluminum barrel design includes sensor grooves on both sides for CMSE reed or DMSE electronic switches, though no magnet is specified for this base configuration.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-75 Is Used
Variable End-Stop Positioning
Dial the retract stroke back by up to 75 mm to accommodate varying material lengths or tooling depths without physically remounting the cylinder.
Production Line Changeover
Rapidly adjust the 60-135 mm travel window during product size transitions to minimize downtime and avoid changing out fixed-stroke actuators.
Heavy-Duty Clamping Setup
Leverage the 14074 N push force at 0.7 MPa to securely clamp large workpieces while fine-tuning the clamping distance at the machine controller.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-75 the Right Cylinder?
Select this 160 mm bore cylinder when your application requires substantial thrust—10053 N pull at 0.5 MPa—and the ability to dial in the exact retract distance on the fly. If you need slightly less force, stepping down to a 125 mm bore yields 5734 N of pull force at 0.5 MPa. Choose the SAIJ adjustable-stroke design over a fixed SAI model when machine setups involve frequent product-size changes or require precise end-position tuning without swapping hardware.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 135 mm stroke, 75 mm adjustment range, PT tapered port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 40 mm rod and M36x2 thread carry high side loads, ensure proper external guiding is used for this 135 mm stroke to prevent premature seal wear.

- ✓ 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 SAIJ160X135-75 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 75 mm. This creates a usable travel window of 60-135 mm, allowing you to fine-tune the retract end position at commissioning without swapping the cylinder.
At 0.5 MPa operating pressure, it provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N.
