The PRL Series rod locks are used in applications where the locking of linear travel is required. They are commonly used in work holding applications and for locking tools and fixtures in the event of air pressure or electrical control failure.

Features/Benefits
• Allows for safe restart of machine in emergency locking situations due to loss of air pressure or e-stop situations

Applications
• Clamping: Without an appropriate air signal to the rod lock pressure port, the rod lock clamps to the precision metric rod and prevents rod movement in the axial direction.
• Delatching: When 4 bar (58 psig) of air pressure is applied to the port, the rod lock releases and allows free movement of the rod. This will be required for installation.
• Locking Direction: The rod lock is designed specifically to prevent rod movement in the axial direction only. It is not recommended for locking rotary rod motion.
• Rod Material: The PRL rod lock is a precision locking device, therefore strict rod tolerances and rod material specifications are required to ensure safe and proper operation. Minimum requirements for the rod materia include a chrome plated surface finish of 10 microinches or less and a surface hardness of 52 Rc. Rod material may be ordered separately in custom lengths.
• Environment: The rod lock is recommended for use in dry, clean conditions. Please take precautions to prevent moisture from entering the pressure port or the exhaust port of the locking device.
