About the AirTAC BSAID40

The AirTAC BSAID40 is a double-rod, double-acting rod-lock ISO 15552 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 BSAID40 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 BSAID40 is the SAID double-rod ISO 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.

Both directions act on the bore area minus the Ø16 mm rod area, because the rod passes through both end covers. Usable force is lower because of friction and back-pressure.

Where the BSAID40 Is Used

Pick-and-place and transfer

About 528 N at 0.5 MPa suits pushers, stoppers and transfer slides.

Intermediate stops

Clamp the rod at any point of the stroke and hold it there while the machine works.

Holding when air is lost

The spring-applied clamp keeps the rod in place when the release port is exhausted.

Choosing the Right BSAID40 Configuration

Start with the stroke. Pick the exact travel your machine needs; a longer stroke adds length, weight and air consumption without adding force. If your length is not listed, request a quote and we will confirm whether it can be built.

Every code on this page is the basic version without a mounting code: the cylinder is fixed through its own mounting holes.

The clamping unit is the same on every code of this page (900 N static holding force). Finally pick the version: S adds a magnet for position sensors.

AirTAC BSAID40 FAQ

The catalog static holding force for Ø40 mm is 900 N. It is a static rating, so stop the rod before the clamp engages; the lock holds in both directions at any stroke position.

Supply 0.15 to 0.7 MPa to the clamp's G1/8 port; with the port exhausted the springs keep the rod clamped. A manual release is also provided.

No. Every BSAID40 gives about 528 N in both directions at 0.5 MPa, whatever the stroke.

1/4" ports, PT thread as standard.

Every code on this page is the basic version without a mounting code; the cylinder is fixed through its own mounting holes.

Usually yes. Request a quote with the stroke, mounting and version and we will confirm whether it can be built, plus price and lead time.

0.15 to 0.7 MPa operating pressure (proof 1.5 MPa) and -20 to +70 °C on filtered air.

No. You can order a single BSAID40. Orders are processed and handed to the carrier within 3-5 business days.
