SKF Rod Ends is a special bearing assembly that is mainly used at both ends of hydraulic or pneumatic pistons to connect cylinders with related components. SKF offers Rod Ends in a variety of designs and specifications, including different thread and shank designs, making them easy to install and maintain
Structure and function SKF Rod Ends consist of an eye-shaped head and an integral shank to form a rod end seat for a spherical plain bearing. This design makes them particularly suitable for a variety of application scenarios, such as connecting components in hydraulic or pneumatic systems
Types and specifications SKF offers a variety of standard Rod Ends, including designs with different sliding contact surface combinations, suitable for a variety of operating conditions. In addition, according to customer needs, SKF can also produce specially designed Rod Ends, such as the SKF Explorer series (suffix ESX) with a steel/steel design
Application scenarios SKF Rod Ends are widely used in a variety of industrial applications that require high-precision connections and low-friction motion. They are particularly suitable for hydraulic or pneumatic systems, engineering machinery, automation equipment and other fields.
SKF Rod Ends are precision-engineered mechanical joints designed to facilitate rotational and angular movement in linkages, control systems, and articulated assemblies. Renowned for their durability and reliability, these rod ends are integral to applications requiring high load capacity, misalignment compensation, and resistance to harsh environments. SKF’s commitment to advanced engineering ensures these components deliver superior performance in industries such as automotive, aerospace, construction, and industrial automation. With options for various materials, seals, and configurations, SKF Rod Ends provide versatile solutions for both standard and specialized applications.
Key Features & Benefits
