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:

  • UCP204 dimensional identification
  • UCP204D1 X AS3S NSK engineering reference—not verified interchangeable
  • Confirm design, suffix, tolerances and approved drawing before substitution
Not an automatic replacement. Match shaft diameter, housing footprint, overall dimensions, center height, bolt spacing, insert configuration and mounting requirements before any substitution is approved.
