Airtac BSE Clamp Standard Cylinder BSE32X350S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE32X350S 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 Ø12mm rod and holds up to 600 N in either direction — no drift. Ø32mm bore, 350mm stroke, PT1/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE32X350S
The AirTAC BSE32X350S is a double-acting, single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a bidirectional static holding force of 600 N with no live air, ensuring suspended loads stay exactly where they stopped if air pressure drops. Operating pressure is capped at 0.7 MPa, and the lock releases via a dedicated G1/8 port.
This 32 mm bore, 350 mm stroke unit uses an extruded aluminum barrel without external tie rods. The -S option includes a magnet for CMSE reed or DMSE electronic sensors. Because the stroke is 350 mm, use adequate guide rails to prevent side-load wear on the front collet and piston seals.
Rod Lock — 600 N Static Holding (Ø32mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE32X350S 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa (max) | 563 N | — |
| Max drive (@0.7 MPa) | 57 kgf | |
Drive force is separate from the 600 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 BSE32X350S Is Used
Z-Axis Pick & Place
Holds a vertical gripper assembly mid-stroke. The 600 N fail-safe collet prevents the 350 mm stroke from crashing downward if an E-stop cuts the main air supply.
Pallet Diverter Gate
Maintains a routing gate position on a packaging line. The spring-applied lock keeps the 32 mm rod rigid against conveyor vibration during air exhaustion.
Tooling Interlock
Secures a light machining fixture in place. The collet clamps the rod instantly on air loss, ensuring the tool does not shift unexpectedly.
Is the Airtac BSE Clamp Standard Cylinder BSE32X350S the Right Cylinder?
Verify your load requires 600 N or less of holding force and under 57 kgf of drive force at 0.7 MPa. If you need less holding capacity, no smaller BSE bore exists. If your load exceeds these figures, step up to the 40 mm bore, which provides 900 N of holding force and 628 N of push force at 0.5 MPa. 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 resuming motion. When replacing, match the 32 mm bore, 350 mm stroke, PT1/8 port, and the -S magnet option. SE mounting accessories fit this body except FTC.
Quick checklist
- ✓ Load to hold ≤ 600 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 BSE32X350S FAQ
The lock is spring-applied and air-released, providing a 600 N bidirectional static hold with no live air. The drive forces are 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a maximum drive of 57 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 first, then allow at least 0.5 s for the collet to fully disengage before commanding cylinder movement.
