Airtac BSE Clamp Standard Cylinder BSE63X400S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X400S 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, 400mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X400S
The AirTAC BSE63X400S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the Ø20 mm rod to deliver a 2200 N bidirectional static holding force. This fail-safe mechanism prevents drift or drops if air is lost, exhausted, or an E-stop trips. Operating pressure is capped at 0.7 MPa.
The lock uses a separate G1/8 release port; the standard adjustable air cushions handle end-of-stroke deceleration, but the collet provides the true holding force. The -S magnet option supports CMSE reed and DMSE electronic sensors for position feedback. Because it uses the SE body, SE mounting accessories fit perfectly, except FTC which is unavailable for BSE.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X400S 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.

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 BSE63X400S Is Used
Vertical Machining Spindle
Holds a 150 kg vertical spindle assembly mid-stroke. The 2200 N fail-safe collet locks instantly on air loss, preventing a crash, while the 1559 N drive handles the machining feed.
Pneumatic Welding Clamp
Secures a steel fixture during a weld cycle. The spring-applied lock maintains 2200 N of clamping force without live air, saving energy while the 2182 N drive repositions the part.
Pallet Diverter Gate
Controls a 400 mm diverter stroke on a packaging line. The lock holds the gate rigidly in place during an E-stop, resisting impact loads up to 2200 N without drifting.
Is the Airtac BSE Clamp Standard Cylinder BSE63X400S the Right Cylinder?
Verify your suspended load stays under the 2200 N holding force. If your load is lighter, the 50 mm bore offers 982 N push at 0.5 MPa and 1400 N holding force. If you need more drive and hold, the 80 mm bore provides 2513 N push at 0.5 MPa and 3600 N holding force. At 400 mm stroke, use a guide to prevent side-load wear on the seals and barrel.
For safe operation, engage the lock only after the rod fully stops. Release it only when pressures on both piston sides are balanced, allowing at least 0.5 s before moving. To replace this unit, match the 63 mm bore, 400 mm stroke, PT3/8 cylinder port, 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 BSE63X400S FAQ
The rod lock is spring-applied and fail-safe. If air is lost, the collet clamps the rod and provides a 2200 N bidirectional static hold, stopping the load at its current position.
The drive force is 1559 N push and 1402 N pull at 0.5 MPa, or 2182 N push at 0.7 MPa (max 222 kgf drive). The static holding force of the lock is 2200 N, which is separate from the drive force.
