Airtac BSE Clamp Standard Cylinder BSE32X450
The AirTAC Airtac BSE Clamp Standard Cylinder BSE32X450 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, 450mm stroke, PT1/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE32X450
The AirTAC BSE32X450 is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a bidirectional fail-safe holding force of 600 N. If air pressure drops, the collet clamps the rod instantly, holding the load securely in both directions without requiring live air.
This 32 mm bore unit runs at 0.15-0.7 MPa operating pressure with a PT1/8 cylinder port and a separate G1/8 lock-release port. The drive force is separate from the holding force, offering a push of 563 N at 0.7 MPa. Note that this specific SKU lacks a magnet, meaning CMSE or DMSE position sensors cannot be used.
Rod Lock — 600 N Static Holding (Ø32mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE32X450 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.

Where the Airtac BSE Clamp Standard Cylinder BSE32X450 Is Used
Vertical Lift Hold
Holds a 600 N vertical lift assembly stationary during air loss, preventing gravity-driven drift on a 450 mm stroke.
Tool Clamp Retention
Maintains a 600 N clamping force on a tooling fixture if the main air supply is exhausted, ensuring the part stays fixed.
Pallet Stop Gate
Keeps a conveyor pallet stop gate firmly positioned during an E-stop event, locking the 450 mm stroke instantly.
Is the Airtac BSE Clamp Standard Cylinder BSE32X450 the Right Cylinder?
Verify your load does not exceed the 600 N static holding force. If you need less holding power, the adjacent 32 mm bore is the smallest available size. If you need more, step up to the 40 mm bore, which provides a 628 N push at 0.5 MPa and a 900 N holding force. Because this is a 450 mm stroke, use a guide to prevent side-load damage to the rod seals.
Engage the lock only after the rod stops moving, and release it only when piston pressures are balanced, allowing at least 0.5 seconds for full release. For replacements, match the 32 mm bore, 450 mm stroke, PT thread, and lack of a magnet. SE mounting accessories fit this body perfectly, except for the FTC variant.
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 BSE32X450 FAQ
The drive force is 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a maximum 57 kgf drive at 0.7 MPa. The separate static holding force of the rod lock is 600 N.
The lock is spring-applied and fail-safe. If air is lost, exhausted, or an E-stop trips, the collet clamps the rod and holds it bidirectionally up to 600 N. To release it, apply 0.15-0.7 MPa to the G1/8 port after balancing piston pressures.
