Airtac BSE Clamp Standard Cylinder BSE63X25S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X25S 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, 25mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X25S
The AirTAC BSE63X25S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 2200 N bidirectional static holding force with no live air, preventing drift when air is exhausted or an E-stop trips. Operating pressure is capped at 0.7 MPa.
This 63 mm bore, 25 mm stroke unit features a separate G1/8 release port to unlock the collet. The standard SE-compatible mounting accessories fit this body, except for FTC. Equipped with a magnet (-S), it supports CMSE reed and DMSE electronic sensors for precise position feedback.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X25S 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 BSE63X25S Is Used
Vertical Pneumatic Press
Holds a 200 kg press platen mid-stroke securely with 2200 N of fail-safe force, preventing a crash if compressed air drops during the forming cycle.
Pallet Stopper Gate
Acts as a rigid stop on a conveyor line. The spring-applied collet locks instantly during an E-stop, withstanding impact loads without drifting backward.
Tooling Clamp
Maintains 1559 N of clamping force at 0.5 MPa, while the mechanical lock ensures the 25 mm stroke stays exactly positioned even if the main air supply is disconnected.
Is the Airtac BSE Clamp Standard Cylinder BSE63X25S the Right Cylinder?
Verify your load requires a holding force of 2200 N or less. If your application needs less drive, the 50 mm bore offers 982 N push at 0.5 MPa and 1400 N holding force. If you need more power, step up to the 80 mm bore, providing 2513 N push at 0.5 MPa and 3600 N holding force. Always engage the lock only after the rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving. To match this cylinder for a replacement, confirm the 63 mm bore, 25 mm stroke, PT3/8 porting, basic mounting, and -S magnet.
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 BSE63X25S FAQ
The spring-applied collet clamps the rod instantly upon air loss, delivering a 2200 N static holding force in both directions. The drive forces are separate: push is 1559 N and pull is 1402 N at 0.5 MPa, push is 2182 N at 0.7 MPa, with a maximum drive of 222 kgf.
You must supply 0.15-0.7 MPa to the separate G1/8 release port. Release the lock only when the pressures on both sides of the piston are balanced, and wait at least 0.5 s before commanding cylinder movement to ensure full disengagement.
