High-speed applications (e.g., fans, motors) require precision or ceramic hybrid bearings to handle heat. Operating Environment:
Before browsing, determine these critical factors to ensure you select a bearing that won't fail prematurely:
Look for specialized heat-resistant materials and lubricants. 2. Measure or Decode Existing Bearings buy ball bearings online
If the application has both, angular contact bearings are ideal.
"ZZ" means two metal shields; "2RS" means two rubber seals. High-speed applications (e
Use sealed (2RS) or shielded (ZZ) bearings to keep contaminants out. Wet/Corrosive: Opt for stainless steel or plastic bearings.
Forces acting perpendicular to the shaft (e.g., wheels, pulleys). Deep groove ball bearings are standard for light to medium radial loads. Measure or Decode Existing Bearings If the application
If the code is unreadable, use a vernier caliper to measure the Inner Diameter (ID) , Outer Diameter (OD) , and Width (W) in millimeters. 3. Choose Reputable Online Suppliers Bearing Selection Guide | How to Choose a Bearing
