    AI Overview
    Open type bearings for industrial pumps and compressors are unsealed rolling element bearings, often featuring a C3 clearance, designed to handle high radial and axial loads while operating under oil lubrication, allowing for high-speed operation and reduced friction. These bearings, such as angular contact and cylindrical roller types (e.g., NTN 6306 N C3), are essential for maintaining shaft alignment, ensuring long life (high MTBF), and minimizing energy loss in centrifugal pumps and rotary compressors. 
    Key Features & Selection Criteria 
    • No Seals/Shields: Open bearings allow lubricant to freely circulate, which is essential for dissipating heat in high-speed and high-load applications.
    • C3 Clearance: Standard pump bearings frequently use C3 clearance, which provides extra internal space to handle thermal expansion.
    • High Load/Speed Capacity: Suitable for demanding tasks, particularly in centrifugal pumps and compressors where shaft positioning is critical.
    • Types: Common types include single-row angular contact ball bearings (often used in pairs), SKF Open Bearings (such as 12476), and cylindrical roller bearings, designed to handle combined axial and radial loads. 
    Applications 
    • Industrial Pumps: Centrifugal pumps, multistage pumps, and vertical pumps.
    • Compressors: Centrifugal and rotary screw compressors. 
    Maintenance and Replacement 
    • Contamination Control: Since they are open, proper lubrication filtering is vital because small, non-sealed components can easily become obstructed by particles or, in some cases, copper paste/debris.
    • Replacement Advice: It is critical to replace with the exact type of bearing, as substituting a sealed or different clearance bearing (e.g., replacing C3 with C1) can lead to premature failure.
