Airtac BSE Clamp Standard Cylinder BSE63X350S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X350S 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, 350mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X350S
The AirTAC BSE63X350S is a double-acting ISO 15552 profile cylinder featuring a 63 mm bore and 350 mm stroke, equipped with a -S magnet for position sensing. It integrates a spring-applied, air-released rod lock that provides a 2200 N bidirectional fail-safe holding force. If air pressure drops or an E-stop trips, the collet clamps the Ø20 mm piston rod, holding the load securely in place without live air.
Operating pressure is capped at 0.7 MPa, and the lock releases via a separate G1/8 port. The cylinder itself uses a PT3/8 port and offers adjustable air cushions at both ends. Because it uses the standard SE body, all SE mounting accessories fit this model except FTC.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X350S 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 BSE63X350S Is Used
Vertical Pallet Lift
Secures a vertical lift stage carrying 150 kg pallets. The 2200 N holding force locks the rod instantly on air loss, preventing the load from crashing down during an E-stop.
Machining Fixture Clamp
Holds a workpiece in place on a CNC line. The 1559 N drive force at 0.5 MPa provides the clamping push, while the mechanical lock maintains the grip if shop air is exhausted.
Pallet Stop Gate
Acts as a mid-conveyor stop gate. The fail-safe collet mechanism ensures the 350 mm stroke stays extended and blocks the lane safely when the line is paused or powered down.
Is the Airtac BSE Clamp Standard Cylinder BSE63X350S the Right Cylinder?
Verify your suspended load requires less than the 2200 N static holding force. If you need less drive power, the 50 mm bore offers 982 N push at 0.5 MPa and 1400 N hold. If you need more holding force, step up to the 80 mm bore, which provides 2513 N push at 0.5 MPa and 3600 N hold. The lock must engage only after the rod stops, and you must allow at least 0.5 s for full release before cycling. Because the 350 mm stroke is over 300 mm, ensure proper guide support to prevent side-loading damage to the rod lock collet. To match this unit exactly, specify bore 63, stroke 350, PT3/8 thread, and the -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 BSE63X350S FAQ
The spring-applied collet clamps the rod automatically on air loss, providing a 2200 N static holding force. The drive forces are separate: push is 1559 N at 0.5 MPa, pull is 1402 N at 0.5 MPa, push is 2182 N at 0.7 MPa, max drive is 222 kgf, and holding force is 2200 N.
The lock is not a dynamic brake. You must engage it only after the rod has completely stopped. To release, balance the air pressure on both sides of the piston and supply air to the separate G1/8 release port, allowing at least 0.5 seconds before commanding movement.
