Airtac BSAID Clamp Cylinder BSAID50X100S
The AirTAC Airtac BSAID Clamp Cylinder BSAID50X100S is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 100mm stroke and a spring-applied, air-released clamp-lock that holds the rod at ANY position along its travel — with a static holding force of 1400 N.

About the Airtac BSAID Clamp Cylinder BSAID50X100S
The AirTAC BSAID50X100-S is a double-acting ISO 15552 profile cylinder featuring a double-rod layout and a spring-applied, air-released clamp-lock. It delivers an equal thrust of 825 N in both directions at 0.5 MPa, while the integrated enclasp mechanism provides a static holding force of 1400 N. Remember that holding force and thrust are separate quantities; you must size the 1400 N clamp capacity against your static load, not the cylinder's push or pull thrust.
Because the rod extends from both ends, you can mount a workpiece on one side and a counterweight or position flag on the other for dual-side guidance. The clamp locks the carbon steel rod at any position along the 100 mm stroke, but only after the piston has stopped moving. A third G1/8 enclasp port releases the lock using 0.15-0.7 MPa air, which requires balanced pressures on both sides of the piston to prevent the rod from jumping abruptly upon release.

How the Clamp-Lock Holds
static holding force (Ø50 mm)
A spring-applied gripper clamps the rod and holds the load at any position in the stroke — not just at the stroke end (that is a SAIL) — and it is bidirectional: it holds whether the rod was extending or retracting.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa (max) | 1374 N | — |
Equal force both directions (double rod). Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (1400 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAID Clamp Cylinder BSAID50X100S Is Used
Mid-Stroke Vertical Hold
Freezes a vertical lifting axis at any point in the travel with 1400 N of holding force, preventing gravity-driven drops during an air pressure loss.
Machining Position Lock
Secures a dual-sided workpiece fixture firmly in place for machining or inspection, using the second rod end for a position flag.
Emergency Drop Prevention
Engages a bidirectional clamp the moment the cylinder stops, providing a reliable static hold to protect operators and tooling.
Is the Airtac BSAID Clamp Cylinder BSAID50X100S the Right Clamp-Lock?
Choose this 50 mm bore when you need equal force both ways and a 1400 N static hold anywhere in the 100 mm travel. If your load is lighter, the 40 mm bore offers 528 N thrust and a 900 N hold; for heavier loads, the 63 mm bore provides 1402 N thrust and a 2200 N hold. This BSAID model outperforms a stroke-end-only SAIL lock when you must freeze the load mid-travel, whereas a plain SAID suffices if holding is handled externally. The clamp is not a moving-rod brake; it engages only after the cylinder stops, and safety-critical applications need an independent backup measure.
For a direct replacement, match the double-rod configuration, 50 mm bore, 100 mm stroke, and PT tapered ports. The BSAID mounting set omits FB, CA, CB, and CR brackets, accepting only Basic, FA, LB, TC, TCM1, and TCM2. The -S suffix indicates a magnet ready for AirTAC CMSE reed and DMSE electronic sensors. The 20 mm rod thread handles side loads well, but for any stroke over 300 mm, add an external guide rail.
Quick checklist
- ✓ Hold needed at any position?
- ✓ Or stroke-end only → use SAIL
- ✓ Holding force ≥ your load
- ✓ Balanced-pressure unlock circuit
- ✓ Extra safety measure for people
Airtac BSAID Clamp Cylinder BSAID50X100S FAQ
The integrated clamp-lock provides a static holding force of 1400 N. It locks the rod at any position along the stroke, but only after the cylinder has stopped moving; it cannot brake a moving load.
The lock is released via a third G1/8 enclasp port using 0.15-0.7 MPa air. You must balance the air pressures on both sides of the piston before unlocking, otherwise the rod can move abruptly. For human safety, an independent backup measure is required.
