About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-40S
The AirTAC SAIJ160X220-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits you to trim the effective travel by up to 40 mm. This yields a usable stroke window of 180-220 mm, allowing precise end-position tuning at commissioning without swapping the cylinder or adding external stops. It delivers robust thrust, generating 10053 N pull force at 0.5 MPa and up to 18095 N at 0.9 MPa.
Equipped with a SUS304 stainless steel rod and PT tapered port threads, this unit is built for durability. The -S magnet option enables direct mounting of AirTAC CMSE reed and DMSE solid-state sensors along the dual-side barrel grooves. It supports speeds of 30-500 mm/s and includes adjustable air cushions at both ends to decelerate heavy loads smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-40S Is Used
Machine Changeover
Dial in the 180-220 mm stroke window during product size transitions without physically replacing the cylinder or bolting on external stoppers.
End-Position Tuning
Fine-tune the retract end-position during commissioning to perfect the seating of heavy 10053 N assemblies using the rear adjustment screw.
Heavy Assembly Press
Leverage the 18095 N push force at 0.9 MPa and adjustable air cushions to safely decelerate and seat large industrial components.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-40S the Right Cylinder?
Choose this 160 mm bore if you need significantly more force than the 125 mm bore (which provides 5734 N pull at 0.5 MPa) but less than the massive 200 mm class. The adjustable stroke is ideal for product changeovers or variable end-stops, whereas a fixed SAI cylinder is preferred for fixed repeatable cycles. For strokes of 300 mm or more, always use an external guide to prevent rod side-load damage.
This SAIJ variant uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Note that the rear adjuster and air cushions only set travel ends and decelerate the load; neither holds the load without live air. For true load-holding without pressure, use a SAIL lock, BSAI clamp-lock, or an external pilot-operated check valve.
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 SAIJ160BX220-40S FAQ
The rear adjuster acts as an external stopper that lets you shorten the 220 mm nominal stroke by up to 40 mm, providing a usable travel window of 180-220 mm for precise end-position tuning during setup.
At 0.5 MPa it provides 10053 N pull force and 14074 N push force. At 0.9 MPa, the push force increases to 18095 N.
