About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-50S
The AirTAC SAIJ160X150-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 100-150 mm, allowing you to dial back the 150 mm nominal stroke by up to 50 mm during machine commissioning. Equipped with a standard carbon steel rod and a -S magnet, it supports AirTAC CMSE reed and DMSE electronic sensors via the dual-side extruded barrel grooves.
In the 160 mm bore class, this model delivers substantial thrust, pushing 18095 N and pulling 9425 N at 0.9 MPa. The robust 40 mm rod and M36x2 thread handle high side-loading forces well, while the PT tapered port thread ensures a tight pneumatic seal. It includes adjustable air cushions at both ends with a 50 mm cushion length to manage heavy kinetic energy.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-50S Is Used
Heavy Press Tuning
Dial in the exact 100 to 150 mm pressing distance for heavy assemblies without machining new hard stops.
Product Changeover
Quickly adapt the end-of-stroke position on a packaging line when switching to a different pallet or product height.
Large Assembly Seating
Use the 18095 N thrust to seat large components, relying on the 50 mm cushion and stroke adjuster to prevent impact damage.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-50S the Right Cylinder?
Choose this 160 mm bore when 125 mm (6136 N push at 0.9 MPa) is insufficient for your heavy loads, but you want to avoid the massive 200 mm frame. The 50 mm adjustment range is perfect for product size changeovers on a line, letting you set new end positions without swapping cylinders or adding external stops. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ will not hold a load without live air, so for fail-safe load holding, consider an SAIL or BSAI cylinder. To replace an ISO 15552 cylinder, match the 160 mm bore, 150 mm stroke, PT ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ160X150-50S FAQ
At 0.9 MPa, this 160 mm bore cylinder provides 18095 N of push force and 9425 N of pull force. At 0.5 MPa, it pushes 10053 N and pulls 9425 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 150 mm nominal stroke down to 100 mm. It sets the travel end and deceleration point, but it does not lock the load without live air pressure.
