Airtac BSE Clamp Standard Cylinder BSE50X225S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X225S 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 1400 N in either direction — no drift. Ø50mm bore, 225mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE50X225S
The AirTAC BSE50X225S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a 1400 N bidirectional fail-safe holding force to prevent drift on suspended loads. Operating pressure is capped at 0.7 MPa, and the lock requires a separate G1/8 release port.
This 50 mm bore unit includes an S-suffix magnet for position sensing with CMSE reed or DMSE electronic switches. The lock is a holding device, not a dynamic brake; engage it only after the piston stops and release it only when pressures are balanced, allowing at least 0.5 seconds for full release before moving.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X225S 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.

| Lock-release port | G1/8 |
| Rod thread | M16×1.5 |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Unlocking pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 30 mm |
| Max stroke | Up to 1000 mm |
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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa (max) | 1374 N | — |
| Max drive (@0.7 MPa) | 140 kgf | |
Drive force is separate from the 1400 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 BSE50X225S Is Used
Vertical Pallet Lifts
Holds a 1400 N vertical load securely on packaging palletizers if compressed air is exhausted, preventing sudden drops.
CNC Tool Holders
Clamps tooling with 982 N push force @0.5 MPa, locking the 225 mm stroke position during an E-stop to avoid collision.
Pallet Transfer Stops
Blocks pallets on a conveyor line; the collet lock maintains the stop position with zero live air, ensuring no drift.
Is the Airtac BSE Clamp Standard Cylinder BSE50X225S the Right Cylinder?
Verify your load requires less than the 1400 N static holding force. If you need less drive force, step down to the 40 mm bore (628 N push @0.5 MPa, 900 N hold); for heavier loads, step up to the 63 mm bore (1559 N push @0.5 MPa, 2200 N hold). Match replacement parts exactly: 50 mm bore, 225 mm stroke, PT1/4 cylinder port, M16x1.5 rod thread, and the -S magnet. At 225 mm stroke, use guide rails to prevent side-load wear on the seals.
Quick checklist
- ✓ Load to hold ≤ 1400 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 BSE50X225S FAQ
The drive force is 982 N push and 825 N pull at 0.5 MPa, and 1374 N push at 0.7 MPa (max 140 kgf). The separate spring-applied rod lock provides a 1400 N bidirectional static holding force with no live air.
Balance the air pressure on both sides of the piston, supply 0.15-0.7 MPa to the G1/8 release port, and wait at least 0.5 seconds before moving. Never engage the lock while the rod is still moving.
