Airtac BSE Clamp Standard Cylinder BSE40X160S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X160S 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 Ø16mm rod and holds up to 900 N in either direction — no drift. Ø40mm bore, 160mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE40X160S
The AirTAC BSE40X160S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 900 N bidirectional static holding force, securely clamping the 16 mm piston rod whenever air is exhausted or E-stop is engaged.
Operating pressure is capped at 0.7 MPa for both the drive and the separate G1/8 release port. Equipped with a -S magnet, this unit supports CMSE reed and DMSE electronic sensors. The extruded aluminum barrel has no external tie rods, maintaining a clean ISO 15552 mounting interface.
Rod Lock — 900 N Static Holding (Ø40mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE40X160S 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa (max) | 880 N | — |
| Max drive (@0.7 MPa) | 90 kgf | |
Drive force is separate from the 900 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 BSE40X160S Is Used
Vertical Pneumatic Lift
Holds a 50 kg vertical lift gate mid-travel. The 900 N clamping force prevents gravity drift instantly if the 0.7 MPa air supply drops.
Tooling Clamp
Secures an aluminum machining fixture. The spring-applied collet maintains the clamp position safely during an emergency air exhaust.
Pallet Stopper
Acts as a fail-safe stop for a 40 kg assembly pallet. The lock engages after the 879 N push force halts the load, keeping it rigid on E-stop.
Is the Airtac BSE Clamp Standard Cylinder BSE40X160S the Right Cylinder?
Verify your suspended load requires 900 N or less of holding force. If you need less drive, the BSE32 bore offers 402 N push at 0.5 MPa and a 600 N hold. If you need more, step up to the BSE50, which provides 982 N push at 0.5 MPa and a 1400 N hold.
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. For the 160 mm stroke, ensure adequate guide support to prevent side-loading. When replacing, match the 40 mm bore, 160 mm stroke, PT1/4 porting, and -S magnet. SE mounting accessories fit this body except FTC.
Quick checklist
- ✓ Load to hold ≤ 900 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 BSE40X160S FAQ
The spring-applied collet clamps the rod automatically on air loss, providing a 900 N static hold. Drive forces are 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, with a max drive of 90 kgf.
You must supply 0.15-0.7 MPa to the separate G1/8 release port. Ensure the pressures on both sides of the piston are balanced before releasing, and wait at least 0.5 s for the collet to fully disengage before commanding motion.
