Look for specialized heat-resistant materials and lubricants. 2. Measure or Decode Existing Bearings
Buying ball bearings online requires matching your specific technical needs—like load type, speed, and environment—to standardized bearing codes and measurements. 1. Identify Your Technical Specifications
Use sealed (2RS) or shielded (ZZ) bearings to keep contaminants out. Wet/Corrosive: Opt for stainless steel or plastic bearings. buy ball bearings online
Forces acting perpendicular to the shaft (e.g., wheels, pulleys). Deep groove ball bearings are standard for light to medium radial loads.
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
If replacing an existing part, use the identification code typically stamped on the ring.
"ZZ" means two metal shields; "2RS" means two rubber seals. Forces acting perpendicular to the shaft (e
If the application has both, angular contact bearings are ideal.
