Forces acting perpendicular to the shaft (e.g., wheels, pulleys). Deep groove ball bearings are standard for light to medium radial loads.
High-speed applications (e.g., fans, motors) require precision or ceramic hybrid bearings to handle heat. Operating Environment:
Bearing type (e.g., "6" is a deep groove ball bearing).
Before browsing, determine these critical factors to ensure you select a bearing that won't fail prematurely:
Use sealed (2RS) or shielded (ZZ) bearings to keep contaminants out. Wet/Corrosive: Opt for stainless steel or plastic bearings.
If replacing an existing part, use the identification code typically stamped on the ring.
Look for specialized heat-resistant materials and lubricants. 2. Measure or Decode Existing Bearings
