Spherical Joint (Ball and Cup)

Categories:

Model No: AGN-1319
It is also known as a ball-and-cup or ball-and-socket joint, is a type of joint that allows movement in multiple directions. It consists of a rounded (ball-shaped) end of one part fitting into a hollow (cup-shaped) socket of another part. This design allows for wide-range rotational movement, making it ideal for both biological and mechanical applications.

Technical Specifications

  • Ball-and-Cup Design: A spherical “ball” fits snugly into a concave “cup” to allow smooth rotation.
  • Multidirectional Movement: Enables motion in almost all directions—flexion, extension, abduction, adduction, and rotation.
  • Three Degrees of Freedom: Offers rotational movement about three perpendicular axes (x, y, and z).
  • High Range of Motion: Allows near-complete rotational freedom (up to 360°).
  • Load Distribution: The cup distributes stress over a wide surface, enhancing durability.
  • Mechanical and Biological Use: Found in human joints (e.g., hip, shoulder) and machines (e.g., robotic arms, automotive ball joints).
  • Material Considerations: Often made from high-strength, wear-resistant materials such as metals, ceramics, or composites.
  • Needs Lubrication: Requires fluid or grease to reduce friction and prolong life.
  • Prone to Wear: Continuous use can lead to wear at the contact surfaces; maintenance or replacement may be needed.
  • Mobility vs. Stability Trade-off: Provides excellent motion but may sacrifice stability if not properly supported.
