90/91-CDNA, Cylinder with Lock, Double Acting, Single Rod

Locking Cylinder series 90-CDNA and 91-CDNA are cylinders with lock, suitable for  mid-stroke stop and emergency stop and drop prevention. 90-CDNA is made from materials compatible with secondary battery manufacturing. 91-CDNA includes a "Lub-retainer" and is compatible with low dew point (40°C) applications.The same holding force in extending and retracting directions is used making it possible to lock at both ends.  Improved brake shoe material and increased length results in stable holding force and high reliability.  Locking mechanism is isolated from lock release air, so lock function is not diminished by excessive dirt or  drain in compressed air.
