About the AirTAC BSAI100
The AirTAC BSAI100 is a double-acting rod-lock ISO 15552 cylinder with a 100 mm bore and a 25 mm piston rod. At 0.5 MPa it pushes 3927 N and pulls 3682 N; at 0.7 MPa that rises to 5498 N push and 5154 N pull. Force depends on bore and pressure only, so every stroke on this page gives the same output.
All BSAI100 versions share 1/2" air ports, an M20×1.5 rod thread and 36 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 1000 mm.
The BSAI100 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 5500 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.

Theoretical output force (Ø100 mm)
| Pressure | Push | Pull |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | 5154 N |
Push = pressure × bore area; pull subtracts the Ø25 mm rod area. Usable force is lower because of friction and back-pressure.

Where the BSAI100 Is Used
Heavy pushing and lifting
About 3927 N at 0.5 MPa moves heavy slides, lifts gates and ejects parts.
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 BSAI100 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 (5500 N static holding force). Finally pick the version: S adds a magnet for position sensors.
AirTAC BSAI100 FAQ
The catalog static holding force for Ø100 mm is 5500 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 BSAI100 gives about 3927 N push and 3682 N pull at 0.5 MPa, whatever the stroke.
1/2" 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 BSAI100. Orders are processed and handed to the carrier within 3-5 business days.
