The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X850S 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, 850mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.
The AirTAC BSE63X850S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 2200 N static holding force in both directions, securing your load the moment air pressure is lost or exhausted. The operating pressure ceiling is 0.7 MPa.
This 63 mm bore, 850 mm stroke model uses a Ø20 mm piston rod with an M16x1.5 thread. The -S magnet option supports CMSE reed and DMSE electronic sensors for precise position feedback. Unlocking requires a separate G1/8 port supplied with 0.15-0.7 MPa.
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X850S 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.

Thread: PT (blank) / G. Mounting (BSE): Basic, LB, FA, FB, CA, CB, CR, TC (FTC is not available on BSE). Related: SE (no lock), BSED (double-rod rod lock). Sensors CMSE/DMSE fit magnetic BSE.
Secures a 200 kg vertical machining axis. The 2200 N fail-safe collet engages instantly on air loss, preventing a crash while the 2182 N drive handles the lifting cycle.
Holds a heavy stamping tool mid-stroke. The spring-applied lock maintains the exact 850 mm position during E-stops, avoiding die damage without needing live air.
Locks a heavy flow diverter in place on a packaging line. The collet holds the gate rigid against 1500 N of impact force when actuation air is removed for safety.
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; for heavier loads, step up to the 80 mm bore providing 2513 N push at 0.5 MPa and 3600 N hold. At 850 mm, this long stroke demands a guide to prevent side-load damage to the seal and barrel.
Engage the lock only after the rod completely stops, and release it solely when piston pressures are balanced, allowing at least 0.5 s before moving. To replace this unit, match the 63 mm bore, 850 mm stroke, PT3/8 port, and -S magnet. SE mounting accessories fit directly, except FTC.
Quick checklist
The spring-applied collet delivers a 2200 N static holding force in both directions 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 max drive of 222 kgf at 0.7 MPa.
The lock is not a dynamic brake. Ensure the rod has completely stopped moving and the pressures on both sides of the piston are balanced. Supply 0.15-0.7 MPa to the separate G1/8 release port, wait at least 0.5 s for full release, and then resume motion.
