    Spherical Plain Bearings

    Spherical plain bearings, also known as ball joint bearings, are components designed for applications that involve swiveling and tilting movements. These bearings consist of an inner ring with a convex spherical surface and an outer ring with a concave spherical surface. This design allows the bearing to handle various types of loads, including radial loads, axial loads, and a combination of both, making it versatile for different mechanical movements. They are suitable in applications where low-speed oscillating movements (angular movements) are required, and they can accommodate tilting motions within a specific angular range, ensuring self-alignment even when there is significant misalignment between the shaft and the housing hole. One of the standout features of these bearings is the self-lubricating capability, thanks to composite materials applied to the outer spherical surface of the inner ring. This ensures smooth operation and durability, especially in environments where maintenance is challenging or where the bearing must function with minimal intervention.

    Basic Information
    • Material

      Typically made from 42CrMo4 steel with induction-hardened raceways for durability, though other materials can be chosen based on specific customer needs.

    • Types

      Available in several configurations, including radial spherical plain bearings, angular contact spherical plain bearings, thrust spherical plain bearings, and rod end spherical plain bearings.

    • Applications

      Widely used in industries such as automotive, aerospace, industrial machinery, agricultural machinery, and rail transport, where reliability and precision are critical.

    • Manufacturing capability

      LYXQL can produce spherical plain bearings with diameters ranging from 200mm to 8000mm, ensuring flexibility in design and application.

    • Customization

      Custom solutions are available to meet specific non-standard requirements, ensuring that the bearings perform optimally in their intended applications.

    What are the benefits of spherical bearings?

    Spherical roller bearings are known for their exceptional service life and operational reliability. Their barrel-shaped rollers minimize friction while reducing noise and vibration during use. A key advantage is their ability to compensate for angular misalignment, making them ideal for applications with shaft deflection or misaligned mounting conditions.

    Should the spherical plain bearing spin within the housing?

    No. Once installed, the spherical plain bearing should remain fixed within the housing. Any rotation should occur between the inner and outer race, not between the bearing and the housing.

    Can a spherical plain bearing replace a tapered roller bearing?

    Yes, in some applications, an angular contact spherical bearing can replace a tapered roller bearing. However, it's important to consult a bearing specialist to determine if this substitution is appropriate for your specific load and alignment conditions.
