What is a Connecting Sleeve?
A connecting sleeve is a mechanical component designed to join two cylindrical parts, such as rods, conductors, or pipes, in a longitudinal arrangement. In hydraulic systems, they are often used to connect hydraulic cylinder rods or hoses, ensuring a leak-proof and mechanically stable connection.
Key Features of Connecting Sleeves:
Facilitate longitudinal connections between round conductors or rods
Provide mechanical stability and electrical continuity where necessary
Available in various materials such as zinc die-cast (ZDC), aluminum (Al), copper (Cu), and plastic (for specific applications)
Comply with industry standards like EN 62561-1 for safety and reliability
Types of Connecting Sleeves in Hydraulic Cylinder Accessories
Connecting sleeves vary widely depending on their specific applications and the materials they connect. Below are the common types relevant to hydraulic cylinder accessories:
1. Zinc Die-Cast (ZDC) Connecting Sleeves
Often used for connecting round conductors or rods in hydraulic systems.
Known for excellent corrosion resistance and mechanical strength.
Clamping range typically around 7-10mm with M6 screws.
2. Aluminum (Al) Connecting Sleeves
Lightweight and corrosion-resistant.
Suitable for air-termination rods and hydraulic components requiring electrical conductivity.
Clamping range around 8mm.
3. Copper (Cu) Connecting Sleeves
Excellent electrical conductivity, making them suitable for hydraulic systems with integrated electrical components.
Clamping range typically 8mm.
4. Cast Resin and Gel-filled Connecting Sleeves
Used primarily for electrical cable connections within hydraulic systems.
Provide watertight and mechanically robust connections.
Ideal for outdoor and underground hydraulic applications requiring protection from environmental factors.
