Airtac BSE Clamp Standard Cylinder BSE50X100S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X100S 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, 100mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.
- BoreØ50 mm

About the Airtac BSE Clamp Standard Cylinder BSE50X100S
The AirTAC BSE50X100S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It provides a bidirectional fail-safe holding force of 1400 N, clamping the Ø20 mm rod via collet to prevent drift when air is exhausted or E-stop is engaged. Operating pressure is capped at 0.7 MPa.
This 50 mm bore unit delivers a drive force of 982 N push and 825 N pull at 0.5 MPa, reaching 1374 N push at 0.7 MPa. The lock uses a separate G1/8 release port and requires 0.5 s for full unlock after pressures balance. The -S option includes a magnet for CMSE reed or DMSE electronic sensors.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X100S 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 (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 BSE50X100S Is Used
Vertical Lift Hold
Holds suspended packaging machine elevators mid-stroke, preventing a 1400 N load from dropping under air loss while delivering 982 N push at 0.5 MPa.
Tool Clamp Security
Secures machining clamps in position during an E-stop, using the collet lock to maintain the hold without live air while the drive provides 825 N pull.
Pallet Gate Stop
Locks a conveyor diverter gate rigidly in place, using the 1400 N static hold to resist impact from pallets while the cylinder cycles at 30-800 mm/s.
Is the Airtac BSE Clamp Standard Cylinder BSE50X100S the Right Cylinder?
Verify your load requires holding force under the 1400 N capacity. If you need less drive force, the 40 mm bore offers 628 N push at 0.5 MPa and 900 N hold; if you need more, the 63 mm bore provides 1559 N push at 0.5 MPa and 2200 N hold. Engage the lock only after the rod fully stops, and release it only when piston pressures are balanced.
For replacement matching, confirm the 100 mm stroke, PT1/4 cylinder port, and M16x1.5 rod thread. SE mounting accessories fit this body except FTC. Because stroke is under 300 mm, standard side-load risks are minimal, but always guide external heavy loads.
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 BSE50X100S FAQ
The spring-applied collet clamps the rod instantly upon air loss, delivering a 1400 N static hold in both directions. Drive forces are 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, with a max drive of 140 kgf.
You must balance pressures on both sides of the piston first. Then supply 0.15-0.7 MPa to the separate G1/8 release port to free the collet, allowing at least 0.5 seconds before commanding movement.
