AirTAC BSCD40 Double-Rod Rod-Lock Cylinder, 40 mm Bore

The AirTAC BSCD40 is a double-rod, double-acting rod-lock tie-rod cylinder with a 40 mm bore and a 16 mm piston rod. The rod runs through both end covers, so push and pull are equal: 528 N at 0.5 MPa and 739 N at 0.7 MPa. Force depends on bore and pressure only, so every stroke on this page gives the same output.

All BSCD40 versions share 1/4" air ports, an M12×1.25 rod thread and 21 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 BSCD40 is the SCD double-rod tie-rod 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.
