About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX195-30
The AirTAC SAIJ50X195-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 165-195 mm, allowing you to dial back the nominal 195 mm stroke by up to 30 mm during commissioning without adding external stops. It delivers 982 N of push force at 0.5 MPa and 1767 N at 0.9 MPa.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster acts purely as a travel stop for deceleration, not a lock.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX195-30 Is Used
End-Position Tuning
Dial in the exact retract distance within the 165-195 mm window during machine setup to perfect product handling without external stops.
Product Changeover
Quickly adapt the stroke on automated lines when switching to a different package size, using the rear screw to set the new travel limit.
Assembly Machine Setup
Fine-tune the clamping or pressing travel on the fly, ensuring delicate components are handled correctly without overtravel.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX195-30 the Right Cylinder?
Choose this 50 mm bore when you need more thrust than the 40 mm version (628 N at 0.5 MPa) but want a lighter frame than the 63 mm option (1559 N). The adjustable stroke is ideal for machine changeovers where exact end-position tuning is required, avoiding the need to swap out a fixed-stroke SAI cylinder. Remember that a plain SAIJ will not hold a load without live air pressure; for true locking, select a SAIL or BSAI model. To replace an ISO 15552 cylinder, match the 50 mm bore, 195 mm stroke, 30 mm adjustment, PT port threads, and the desired mounting accessory.
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 SAIJ50 Adjustable Cylinder SAIJ50BX195-30 FAQ
At a 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.9 MPa, the push force increases to 1767 N.
The rear adjuster screw lets you shorten the effective travel from the 195 mm nominal stroke down to as little as 165 mm. This stopper fine-tunes the end position but does not lock the load without live air.
