Airtac BSE Clamp Standard Cylinder BSE63X75
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X75 is a genuine double-acting ISO 15552 cylinder with an integrated spring-applied, air-released ROD LOCK. If air is cut or an E-stop is hit, the collet clamps the Ø20mm rod and holds up to 2200 N in either direction — no drift. Ø63mm bore, 75mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X75
The AirTAC BSE63X75 is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the Ø20 mm piston rod, delivering a 2200 N bidirectional holding force with zero live air. Operating pressure is capped at 0.7 MPa, and a separate G1/8 port unlocks the mechanism.
This fail-safe lock engages automatically if air is exhausted or an E-stop trips, holding the rod precisely where it stopped. It is a static lock, not a dynamic brake—engage it only after the rod stops, and allow at least 0.5 s for full release before moving. The 75 mm stroke unit uses adjustable air cushions at both ends and lacks a magnet, meaning no position sensing on this SKU.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X75 holds its position in both directions when air is lost, exhausted or an E-stop trips. Apply 0.15–0.7 MPa to the G1/8 release port to unlock. Engage the lock only after the rod has stopped (it is not a dynamic brake), and release only when the pressures on both sides of the piston are balanced. Allow at least 0.5 s for full release before moving.

Specifications follow the official AirTAC BSE datasheet. The lock uses the SE standard body; SE mounting accessories fit BSE except FTC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa (max) | 2182 N | — |
| Max drive (@0.7 MPa) | 223 kgf | |
Drive force is separate from the 2200 N static holding force of the lock. BSE operates up to 0.7 MPa. Size with a safety margin.

Where the Airtac BSE Clamp Standard Cylinder BSE63X75 Is Used
Vertical Machining Spindle
Secures a 63 mm bore vertical spindle mid-stroke, providing 2200 N of fail-safe holding force to prevent gravity drops during a sudden air loss or E-stop.
Injection Mold Clamp
Holds a mold halting jig firmly in place with 2200 N of static grip when shop air is exhausted, ensuring the tooling does not drift or shift unexpectedly.
Pallet Lift Stopper
Locks a 75 mm stroke pallet diverter gate rigidly in position using the spring-applied collet, keeping the lane blocked even if the main air supply drops out.
Is the Airtac BSE Clamp Standard Cylinder BSE63X75 the Right Cylinder?
Verify your suspended load stays under the 2200 N holding capacity. If you need less force, step down to bore 50 (982 N push @0.5 MPa, 1400 N hold). If you need more, step up to bore 80 (2513 N push @0.5 MPa, 3600 N hold). SE mounting accessories fit this body perfectly, except FTC. To replace correctly, match the 63 mm bore, 75 mm stroke, PT3/8 port, and basic mounting.
Quick checklist
- ✓ Load to hold ≤ 2200 N?
- ✓ Fail-safe hold on air loss / E-stop needed
- ✓ Lock engaged only when stopped
- ✓ G1/8 release-air line available
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Safety Notes
- check Engage the lock only after the rod has stopped — not as a dynamic brake.
- check Release only when both piston sides are pressure-balanced.
- check Allow ≥0.5 s for full release before commanding motion.
- check Feed the G1/8 release port with 0.15–0.7 MPa clean air.
- check Add safety-rated controls for man-rated / overhead loads.
- check Use SE mounting accessories (FTC excepted).
Airtac BSE Clamp Standard Cylinder BSE63X75 FAQ
The spring-applied collet instantly clamps the rod, providing a 2200 N bidirectional static hold. It is a fail-safe lock, not a dynamic brake, so it only engages after the rod has stopped moving.
At 0.5 MPa, push force is 1559 N and pull is 1402 N. At the 0.7 MPa ceiling, push is 2182 N (max 222 kgf). This drive force is separate from the 2200 N static holding force of the lock.
