Product advantages and features
Prevent Hose Damage: By allowing rotation, hydraulic swivel connectors prevent hoses from twisting, kinking, and excessive bending, which can significantly extend the service life of hoses and reduce maintenance needs.
Absorb Hydraulic Surges and Shocks: They can absorb sudden pressure increases and shocks in the hydraulic system, protecting the system components from damage.
High Pressure Resistance: Tight tolerances and quality construction make them suitable for high-pressure applications, often capable of handling pressures as high as 5,000 psi or more.
Versatile and Flexible: The ability to rotate 360 degrees or have restricted rotation angles makes them adaptable to various equipment and operating conditions, providing flexibility in hydraulic system design.
Product Type
High-Pressure Swivels: Specifically designed for high-pressure applications, often featuring stainless steel ball bearings. They are commonly used in mining, railroad, and robotic equipment and can fit in relatively tight areas.
Ball-Less Couplings: Can handle side loads and pressures up to 6,000 psi. They are easy to install and usually have a restricted rotation of up to 90 degrees, making them suitable for narrow spaces.
In-Line Swivels: Provide a direct fluid path without changing the direction of flow, with the opposing stem and housing fluid ports lying on a common axis.
90° Swivels (Elbow Swivels): Alter the fluid's flow direction by 90 degrees, accommodating different installation needs.
Product Application
Industrial Equipment: Commonly used in robotic arms, hydraulic actuators, mining equipment, forestry machinery, lift cranes, utility boom trucks, railroad maintenance equipment, and demolition shears.
Maritime Industry: Applied in ship cranes, winches, and steering mechanisms.
Automotive Industry: Used in car wash systems and some automotive manufacturing equipment.
Food and Beverage Processing: Stainless steel swivel connectors are used in processing equipment for easy cleaning and to avoid contamination.
Product material
Metals
- Carbon Steel: It is the most commonly used material due to its high strength and durability, which can withstand high-pressure hydraulic systems. It is also relatively inexpensive, making it a cost-effective choice for many applications. However, carbon steel is prone to rust and corrosion, especially in wet and humid environments, so it often requires additional surface treatment, such as painting or galvanizing, to improve its corrosion resistance.
- Stainless Steel: It is preferred in applications where corrosion resistance is crucial, such as in the food and beverage processing, marine, and offshore industries. Stainless steel has excellent resistance to rust, acids, and alkalis, and can maintain good performance and appearance in harsh environments. It is available in different grades, such as 304 and 316, with 316 offering even higher corrosion resistance, especially in chloride-rich environments.
- Brass: It is sometimes used for its good corrosion resistance and machinability. Brass hydraulic swivel connectors are often found in applications where a certain degree of electrical conductivity is required or where a more decorative appearance is desired. It is also suitable for low-pressure hydraulic systems. However, brass is relatively soft compared to steel and stainless steel, so it may not be suitable for high-pressure and high-load applications.
- Aluminum: It is used in some hydraulic swivel connectors for its lightweight and good corrosion resistance properties1. It is particularly beneficial in applications where weight reduction is important, such as in the aerospace and automotive industries. However, aluminum has a lower strength than steel and stainless steel, so the design of aluminum swivel connectors needs to take into account the strength requirements to ensure safe and reliable operation.
