Product Introduction
The Spherical Combination Bearing is a high-performance sliding bearing that integrates radial load-bearing, axial load-bearing, and self-aligning capabilities. It is suitable for industrial equipment subject to heavy loads, impacts, and vibrations, as well as applications involving installation misalignment.
Key Advantages
Features a composite structure capable of simultaneously bearing radial and axial loads, meeting the demands of complex operating conditions and enhancing equipment reliability.
The spherical structure compensates for shaft misalignment and installation errors, reducing localized wear and improving operational stability.
Utilizes wear-resistant materials-such as bronze, PTFE composites, or Babbitt alloy-to minimize frictional loss and reduce maintenance frequency.
Application Areas
Heavy Machinery
Used in connection points for construction machinery, mining equipment, and lifting gear, meeting the requirements of high-load and high-impact conditions.
Hydraulic Equipment
Applied in hydraulic cylinders, gate hoists, and similar equipment to enhance motion stability and service life.
Marine and Industrial Equipment
Used in marine propulsion systems, deck machinery, and industrial transmission equipment, ensuring performance in complex operating environments.
Product Structure
Bearing Housing
Manufactured from carbon steel, cast steel, or alloy materials; material grades are selected based on operating conditions to ensure structural strength and dimensional stability.
Spherical Sliding Surface
Features a spherical mating design that automatically adjusts the operating angle to compensate for shaft misalignment and installation errors.
Sliding Layer
Available in bronze, bimetallic materials, PTFE composites, or Babbitt alloy to meet various load and lubrication requirements.
