Applications

The bearing number is only the starting point. Load, speed, temperature, contamination, alignment and service-life targets determine the final selection.

These industry links are engineering review paths, not model-specific recommendations. Final bearing selection should be confirmed against the actual load, speed, fit, clearance, lubrication, environment and application requirements.

07 · Cross-reference screening

Replacement / Interchange

Possible search and drawing-reference candidates:

  • 6203 open
  • 6203-ZZ / 6203-2Z shielded
  • 6203-2RS sealed
Not an automatic replacement. Match bore diameter (d), outside diameter (D), width (B), internal clearance, sealing, cage, precision, lubrication and load requirements before any substitution is approved.
