Closed Centre Hydraulic Cylinder
Closed center hydraulic cylinders feature high speed and long stroke options for use with all closed center chucks with speeds up to 6000 RPM. These cylinders contain a safety provision in case of an interruption of hydraulic pressure such as: electric power loss, broken hydraulic hose, hydraulic pump failure, etc
YR series Closed Centre Hydraulic Cylinder
- Safety check valves to ensure safety in the event of hydraulic failure * Safety pressure relief valve to prevent damage to cylinders in the event of over pressure * High speed, compact and lightweight * Maintenance free design
