About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX95-50S
The AirTAC SAIJ50X95-50-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 50 mm. This yields a highly flexible 45-95 mm usable positioning window, enabling precise end-stop tuning directly at the machine without swapping out the barrel or adding external stops. It delivers 982 N of push force and 825 N of pull force at 0.5 MPa, making it a robust choice for mid-range actuation.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this unit includes a magnet for position sensing. The extruded aluminum barrel features sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE solid-state switches. It operates at speeds from 30-800 mm/s, uses PT tapered G1/4 ports, and includes adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX95-50S Is Used
Product Changeover Tuning
Dial in the exact 45-95 mm end-stop during format or product size changes on a packaging line without replacing the cylinder or bolting on external stops.
Machine Setup Calibration
Fine-tune the retract position during initial commissioning to perfect the gripping or pressing distance, using the rear screw to dial out mechanical slack.
Variable End Stops
Provide an adjustable physical stop for actuators routing items of varying lengths, allowing operators to quickly adapt the travel window on the fly.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX95-50S the Right Cylinder?
Choose this 50 mm bore when a 40 mm bore (providing 628 N push at 0.5 MPa) is too weak, but you want to avoid the bulk of a 63 mm bore (1559 N push). The 50 mm class hits a sweet spot for 95 mm nominal strokes requiring exact positioning. The rear adjuster acts purely as a mechanical stop to set the travel end; it does not lock the load or hold position without live air pressure. For fail-safe load holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
As a dimensionally interchangeable ISO 15552 profile cylinder, this model matches standard SAI footprint dimensions. It supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The -S magnet pairs directly with AirTAC CMSE and DMSE sensors, and the PT threaded ports ensure a tight, tapered pneumatic seal.

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 SAIJ50 Adjustable Cylinder SAIJ50BX95-50S FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the 95 mm nominal stroke by up to 50 mm. This creates a usable travel window of 45-95 mm, which can be fine-tuned during commissioning. The adjuster only sets the travel end and does not lock the load without live air pressure.
At 0.5 MPa, it provides 982 N of push force and 825 N of pull force. Equipped with a magnet (-S), it works seamlessly with AirTAC CMSE reed switches and DMSE solid-state sensors mounted in the dual-side barrel grooves.
