Airtac BSE Clamp Standard Cylinder BSE63X50
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X50 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, 50mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X50
The AirTAC BSE63X50 is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 2200 N bidirectional static holding force with no live air, providing true fail-safe protection for suspended loads. Operating pressure is capped at 0.7 MPa, and the separate G1/8 release port unlocks the collet only when piston pressures are balanced.
This 63 mm bore, 50 mm stroke unit uses a 20 mm rod with an M16x1.5 thread and PT3/8 cylinder ports. The lock is a holding device, not a dynamic brake; engage it only after the rod fully stops and allow at least 0.5 s for release before cycling. This SKU lacks a magnet, so it does not support position sensing.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X50 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 BSE63X50 Is Used
Vertical Pneumatic Lift
Holds a 200 kg vertical lift mid-stroke. The 2200 N collet engages instantly on air loss to prevent crashing, while the 1559 N drive handles the upward push.
Tooling Clamp
Secures machining tooling that must not drop if air exhausts. The fail-safe lock holds the load without live air, unlike a standard double-acting cylinder.
Safety Gate Stop
Blocks an automated safety gate during an E-stop. The spring-applied collet locks the 20 mm rod in both directions until the G1/8 release port is pressurized.
Is the Airtac BSE Clamp Standard Cylinder BSE63X50 the Right Cylinder?
Verify your load requires 2200 N or less of holding force and 1559 N push at 0.5 MPa. If you need less force, step down to the 50 mm bore, which provides 982 N push and 1400 N holding force. If your load exceeds this unit, step up to the 80 mm bore for 2513 N push and 3600 N holding force. The drive force is separate from the holding force.
Match your replacement exactly by confirming the 50 mm stroke, PT3/8 port, and lack of an S suffix. Because this is a short 50 mm stroke, side-load risks are minimal, but always ensure the rod is stopped before engaging the lock. SE 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 BSE63X50 FAQ
The spring-applied collet provides a 2200 N bidirectional static hold with no live air. The drive forces are 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a max drive of 222 kgf.
The lock is not a dynamic brake. Engage it only after the rod stops. To release, balance pressures on both sides of the piston and supply 0.15-0.7 MPa to the G1/8 release port, allowing at least 0.5 s before moving.
