Airtac BSE Clamp Standard Cylinder BSE50X700S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X700S 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 1400 N in either direction — no drift. Ø50mm bore, 700mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE50X700S
The AirTAC BSE50X700S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the 20mm rod automatically, providing a fail-safe bidirectional static holding force of 1400 N. If air is lost or an E-stop trips, the load is held securely at its stopped position without requiring live air.
Operating pressure is capped at 0.7 MPa, and unlocking requires 0.15-0.7 MPa supplied to the separate G1/8 release port. The lock is a holding device, not a dynamic brake; it must only engage after the rod stops. Equipped with a magnet (-S), this model supports CMSE reed and DMSE electronic sensors for position feedback.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X700S 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa (max) | 1374 N | — |
| Max drive (@0.7 MPa) | 140 kgf | |
Drive force is separate from the 1400 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 BSE50X700S Is Used
Vertical Pneumatic Lift
Holds a 1400 N vertical load in place instantly if supply air drops, preventing a raised machining fixture from crashing down.
Tool Clamp Station
Maintains 1400 N of clamping force on a workpiece during an E-stop, ensuring parts remain fixed while pressure is exhausted.
Pallet Stop Gate
Acts as a 700mm stroke stop gate that locks firmly mid-stroke, keeping the pathway clear and secure during maintenance cycles.
Is the Airtac BSE Clamp Standard Cylinder BSE50X700S the Right Cylinder?
Verify your load to hold does not exceed the 1400 N static holding force. If your application needs less drive force, the adjacent 40mm bore offers a 628 N push at 0.5 MPa and 900 N hold. If more force is required, the 63mm bore provides a 1559 N push at 0.5 MPa and 2200 N hold.
When replacing, match the 50mm bore, 700mm stroke, PT1/4 port, and mounting style. Note that standard SE mounting accessories fit this body perfectly, except FTC. Because the 700mm stroke is highly extended, ensure external guides are used to prevent side-load damage to the rod seals.
Quick checklist
- ✓ Load to hold ≤ 1400 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 BSE50X700S FAQ
The drive force at 0.5 MPa is 982 N push and 825 N pull; at 0.7 MPa, push is 1374 N (max 140 kgf). The integrated rod lock provides a separate 1400 N static holding force.
The spring-applied collet clamps the rod instantly, providing a 1400 N bidirectional hold with no live air. To release it, apply air to the G1/8 port only after the piston is pressure-balanced, allowing at least 0.5 seconds before moving.
