Airtac SAIJ200 Adjustable Cylinder SAIJ200BX195-40

Selecting this 200 mm bore model is appropriate when an application requires extreme thrust—up to 28074 N push at 0.9 MPa—combined with on-the-fly travel adjustments. If a smaller force class is acceptable, stepping down to the 160 mm bore yields 10053 N of push at 0.5 MPa. The adjustable stroke is ideal for product changeovers or variable end-stops, whereas a fixed-stroke SAI cylinder is sufficient for static, repeatable positions. Because the stroke is 195 mm, an external guide rail is recommended to support the heavy load and prevent undue side-load wear on the rod seals.

When replacing an ISO 15552 cylinder, match the 200 mm bore, 195 mm nominal stroke, 40 mm adjustment range, G3/4 port size, and PT thread type. The SAIJ mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories, omitting FB, CA, CB, and CR options. Note that this plain SAIJ model lacks a magnet; if position feedback is needed, a -S suffix version is required to host CMSE reed or DMSE electronic sensors. For true load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is not a locking mechanism.
