About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X20-10S
The AirTAC SAIJ160X20-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 10 to 20 mm, allowing you to dial back the nominal 20 mm stroke by up to 10 mm during commissioning. The 160 mm bore generates 10053 N of push force at 0.5 MPa, making it suited for heavy-duty pressing and clamping. A carbon steel piston rod and PT tapered port threads are standard.
This adjustable model omits the FB, CA, CB, and CR mounts, offering a focused mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports CMSE reed and DMSE solid-state switches. The rear adjuster acts purely as a travel stop for end-position tuning, not as a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X20-10S Is Used
Heavy-Duty Pressing
Delivers up to 18095 N of push force at 0.9 MPa for short-stroke forming, riveting, and stamping operations.
Changeover Adjustment
The 10 mm adjustment range allows operators to fine-tune the end position quickly when switching between product variants on the line.
Heavy Clamping Fixtures
Provides robust holding force for securing large workpieces during machining, with the rear stop ensuring exact clamping depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X20-10S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires massive force within a very short travel distance, specifically a 10 to 20 mm adjustable window. If you need less force, stepping down to a 125 mm bore yields 6136 N of push force at 0.5 MPa. The rear adjuster is chosen over a fixed-stroke SAI cylinder when you need variable end-stops for product changeovers without swapping hardware.
Because this is a double-acting cylinder, the rear adjuster and air cushions only decelerate the travel end; they do not hold the load without live air. For load-holding without pressure, consider the SAIL or BSAI series. This model uses a PT tapered G3/4 port, and despite the short 20 mm stroke, the 40 mm rod diameter handles high side loads effectively.
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 SAIJ160X20-10S 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 acts as a mechanical stop that shortens the effective travel. For this SAIJ160X20-10-S model, you can trim the 20 mm nominal stroke back by up to 10 mm, creating a 10 to 20 mm usable travel window for precise end-position tuning.
