Airtac BSE Clamp Standard Cylinder BSE63X500S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X500S 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, 500mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X500S
The AirTAC BSE63X500S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a bidirectional static holding force of 2200 N with no live air required, preventing drift during pressure loss or E-stop events. Operating pressure is capped at 0.7 MPa, and the lock uses a dedicated G1/8 release port.
This 63 mm bore, 500 mm stroke variant includes a magnetic piston for CMSE reed or DMSE electronic sensors. The lock is a holding device, not a dynamic brake; engage it only after the rod stops and release it only when piston pressures are balanced, allowing at least 0.5 seconds for full release before moving. The extruded aluminum barrel design ensures ISO 15552 dimensional interchangeability without external tie rods.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X500S 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 BSE63X500S Is Used
Vertical Lift Hold
Suspends a 150 kg packaging elevator stage mid-travel. The 2200 N collet lock engages instantly on air loss, preventing a catastrophic drop without needing continuous live air.
Machining Clamp
Holds a heavy casting block against 2182 N of cutting tool thrust. The fail-safe lock maintains the clamped position securely if the main air supply drops during the cycle.
Pallet Stop Gate
Acts as a 500 mm stroke stop for heavy pallets on an assembly line. The spring-applied lock holds the 1559 N drive force barrier firmly in place during E-stop activations.
Is the Airtac BSE Clamp Standard Cylinder BSE63X500S the Right Cylinder?
Verify your load to be held is under the 2200 N static holding force limit. For sizing context, the adjacent 50 mm bore provides 982 N push at 0.5 MPa and 1400 N holding force, while the 80 mm bore provides 2513 N push at 0.5 MPa and 3600 N holding force. This 500 mm stroke requires external guide rails to prevent side-load damage to the seals and lock collet.
Always engage the lock only after the rod stops moving, and release it only when pressures are balanced, allowing at least 0.5 s before commanding motion. When replacing a unit, match the 63 mm bore, 500 mm stroke, PT3/8 cylinder port, and confirm the -S magnet option. SE-compatible mounting accessories fit this body, except 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 BSE63X500S FAQ
The lock is spring-applied and fail-safe. If air is lost or exhausted, a collet clamps the rod and holds it in both directions with a 2200 N static holding force. It is not a dynamic brake; the rod must be stopped before engagement.
The drive force is 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, with a max drive of 222 kgf. The static holding force is 2200 N. Unlocking requires 0.15-0.7 MPa applied to the G1/8 release port, taking at least 0.5 s after pressures are balanced.
