Seal Options

01Open bearing arrangement; external sealing is application-defined

Open, ZZ and 2RS are separate configurations for deep groove ball bearings. For roller, insert and mounted bearings, sealing is defined by the bearing and housing arrangement shown above.

06 · Application paths

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:

  • 30204 dimensional identification
  • 30204 Timken engineering reference—not verified interchangeable
  • Confirm design, suffix, tolerances and approved drawing before substitution
Not an automatic replacement. Match bore diameter (d), outside diameter (D), total width (T), and where applicable inner-ring width (B) and outer-ring width (C), together with internal design, preload or clearance, lubrication and load requirements before any substitution is approved.
