Airtac BSE Clamp Standard Cylinder BSE63X900S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X900S 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, 900mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X900S
The AirTAC BSE63X900S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It provides a fail-safe static holding force of 2200 N in both directions without requiring live air. If pressure drops or an E-stop trips, the collet clamps the 20 mm piston rod instantly to secure the load.
Operating pressure is capped at 0.7 MPa, and a separate G1/8 release port unlocks the mechanism. The -S magnet option enables position sensing with CMSE reed or DMSE electronic switches. Because the stroke is 900 mm, the extruded aluminum barrel lacks external tie rods while maintaining ISO 15552 mounting interchangeability.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X900S 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 (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 BSE63X900S Is Used
Vertical Z-Axis Lift
Secures an elevated machining head weighing 150 kg. The 2200 N lock prevents gravity drift during air loss, while the 2182 N drive force handles the vertical lift.
Pallet Stop Gate
Holds a 900 mm extended stop pin rigid against heavy pallet impacts. The spring-applied collet keeps the barrier locked even if the shop air supply is exhausted.
Tooling Clamp
Maintains a clamped fixture position on an automated press. The fail-safe collet holds the load securely in both directions when the machine enters E-stop.
Is the Airtac BSE Clamp Standard Cylinder BSE63X900S the Right Cylinder?
Verify your suspended load requires 2200 N or less of holding force. If you need less drive, the 50 mm bore offers 982 N push at 0.5 MPa and 1400 N hold; if you need more, the 80 mm bore provides 2513 N push at 0.5 MPa and 3600 N hold. The lock is not a dynamic brake: engage it only after the rod stops completely, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving.
At 900 mm stroke, side loads are magnified. Use a guide rail to prevent rod bending and premature seal wear. This replacement must match the 63 mm bore, 900 mm stroke, PT3/8 cylinder port, and -S magnet. SE mounting accessories fit this body perfectly except for FTC.
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 BSE63X900S FAQ
A spring applies a collet to the rod, delivering 2200 N of bidirectional static holding force with no live air. The drive forces are separate: 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a maximum drive of 222 kgf.
You must balance the air pressure on both sides of the piston before unlocking. Supply 0.15-0.7 MPa to the G1/8 release port, wait at least 0.5 s for the collet to fully retract, and then command movement. Never engage the lock while the rod is moving.
