Key Considerations for Selecting Spherical Plain Bearings
May 25,2026
Consider the machine’s inherent structural requirements for support, such as the location and arrangement of supports, as well as the magnitude of axial thermal expansion and contraction.
Space at the mounting location and shaft dimensions: Ensure the bearing can be smoothly installed and securely fastened in the designated position.
The loads borne by the bearing—including magnitude, direction, and nature—must be considered in selecting the appropriate bearing type and size.
Bearing service life and reliability requirements: Select the appropriate bearing brand and model based on the equipment’s service life and reliability requirements.
Operating speed: Consider the bearing’s maximum permissible speed and the requirements for both forward and reverse rotation to ensure stable operation and long service life at high speeds.
Ambient temperature: Depending on requirements for high-temperature or low-temperature resistance, select appropriate bearing materials and lubrication methods.
Requirements for the surrounding medium, dustproofing, moisture resistance, and waterproofing: to ensure the bearing’s normal operation and service life under harsh environmental conditions.
