About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-75
The AirTAC SAIJ160X200-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 75 mm. This creates a highly flexible 125-200 mm usable window, letting you dial in the exact retract position during commissioning without swapping out the barrel or adding external stopper blocks. It delivers serious thrust, generating 10053 N of pull force at 0.5 MPa and up to 18095 N at 0.9 MPa.
This specific SKU is configured with a SUS304 stainless steel rod (material code B) for superior corrosion resistance in harsh environments, alongside PT tapered G3/4 port threads. The extruded aluminum barrel includes sensor grooves on both sides for mounting standard switches. Remember that the rear adjuster acts only as a travel stop to fine-tune deceleration alongside the built-in air cushions; it is not a lock and will not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-75 Is Used
Variable End-Stop Tuning
Perfect for packaging lines running multiple carton sizes, allowing operators to dial back the stroke by up to 75 mm to hit the exact retract position without changing hardware.
Heavy Press Commissioning
Provides 18095 N of thrust at 0.9 MPa for heavy pressing operations, while the rear screw permits micro-adjustments to the end position during initial machine setup.
Corrosive Environment Actuation
The SUS304 stainless steel rod handles demanding industrial settings, providing reliable high-force motion where standard carbon steel rods would risk degradation.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-75 the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore falls short—yielding 2268 N of pull at 0.5 MPa compared to the 80 mm's capacity—and when you need on-the-fly end-position tuning for product changeovers. The adjustable stroke is ideal for variable end stops, whereas a fixed SAI cylinder locks you into one exact dimension. Because the 200 mm stroke exceeds 150 mm, ensure an external guide supports the load, as even the robust 40 mm rod and M36x2 thread cannot safely counteract excessive side-loading on long unsupported travels.
For an exact ISO 15552 dimensional replacement, match the 160 mm bore, 200 mm stroke, 75 mm adjustment range, PT G3/4 ports, and SUS304 rod material. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). If your application requires true load-holding without continuous air pressure, step up to the SAIL air-released lock or BSAI clamp-lock cylinder instead of relying on this adjuster.

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 SAIJ160BX200-75 FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw lets you shorten the 200 mm nominal stroke by up to 75 mm, creating a usable travel window of 125-200 mm. This mechanical stop fine-tunes the end position but does not lock the load without live air pressure.
