AirTAC BSAI40 Rod-Lock ISO Cylinder, 40 mm Bore

The AirTAC BSAI40 is a double-acting rod-lock ISO 15552 cylinder with a 40 mm bore and a 16 mm piston rod. At 0.5 MPa it pushes 628 N and pulls 528 N; at 0.7 MPa that rises to 880 N push and 739 N pull. Force depends on bore and pressure only, so every stroke on this page gives the same output.

All BSAI40 versions share 1/4" air ports, an M12×1.25 rod thread and 30 mm adjustable air cushions. The cylinder runs on filtered air between 0.15 and 0.7 MPa (proof 1.5 MPa), from -20 to +70 °C, at 30 to 800 mm/s. This page lists 44 stock order codes with strokes from 25 to 1000 mm; catalog standard strokes run up to 800 mm, and the longer codes are non-standard strokes that we confirm with the quote.

The BSAI40 is the SAI ISO 15552 cylinder with a compact clamping unit built in. Springs apply clamp plates to the piston rod and air releases them, so the rod can be locked at any point of the stroke, in either direction and whether it is extended or retracted. Static holding force at this bore is 900 N. The clamp has its own G1/8 port and releases at 0.15 to 0.7 MPa; it can also be released by hand. The holding force is a static rating: stop the rod first, then clamp it.
