About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-50
The AirTAC SAIJ160X160-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers robust thrust, generating 10053 N of pull force at 0.5 MPa and up to 18095 N at 0.9 MPa. The built-in adjustment mechanism allows you to trim the effective stroke by up to 50 mm, creating a precise 110-160 mm usable travel window for exact end-position tuning.
This extruded aluminum barrel features sensor grooves on both sides for direct mounting of CMSE or DMSE switches. The 40 mm carbon steel piston rod utilizes an M36x2 thread, providing substantial rigidity. It uses PT tapered port threads and includes variable air cushions at both ends to manage heavy deceleration.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-50 Is Used
Heavy Machinery Changeover
Dial in the 110-160 mm retract position during heavy equipment assembly line changeovers without replacing the entire cylinder.
Press Positioning
Fine-tune the end-stop for large pressing or clamping operations, ensuring exact contact depth on varying product sizes.
Actuator Setup
Achieve precise end-position calibration at commissioning, using the 50 mm rear adjustment screw to perfect the stroke window.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-50 the Right Cylinder?
Choose this 160 mm bore when your application requires significantly more force than a 125 mm bore provides, which yields 6136 N of push force at 0.5 MPa. The 50 mm adjustment range is ideal for machine setups requiring variable retract end-stops during product changeovers, eliminating the need to swap cylinders or bolt on external stops. For true load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ rear adjuster functions strictly as a travel stop, not a lock. To match this ISO 15552 replacement exactly, specify: 160 mm bore, 160 mm stroke, 50 mm adjustment, PT G3/4 port, and no 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 SAIJ160X160-50 FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 160 mm stroke by up to 50 mm, resulting in a 110-160 mm usable travel window. It sets the end position but does not lock the load without live air.
