Selection and InstallationSelection Considerations:
Choose the contact angle based on load direction: A larger contact angle is suitable for higher axial loads, while a smaller contact angle is better for higher radial loads.
Select the bearing type based on speed: High-speed applications require high-speed angular contact ball bearings or ceramic ball bearings.
Choose single-row or double-row bearings based on installation space.
Installation Notes:
Angular contact ball bearings are often installed in pairs to ensure bidirectional load capacity.
Pay attention to the bearing orientation during installation to ensure the load acts on the correct contact angle.
Use dedicated tools for installation to avoid direct hammering on the bearing.
Advantages and LimitationsAdvantages:
High-speed capability.
High precision and rigidity.
Combined load capacity.
Compact design, saving space.
Limitations:
Single-row bearings can only withstand unidirectional axial loads.
Installation and adjustment are relatively complex, requiring expertise and specialized
Maintenance and CareRegularly inspect the lubrication condition to ensure sufficient and clean lubricant.
Avoid overloading or impact loads to prevent bearing damage.
For high-speed or high-temperature applications, choose high-temperature lubricants or special material bearings.
