Before Selecting a Replacement
Record the complete marking on the original bearing. Verify bore, outside diameter and width, then compare seals or shields, internal clearance, cage, tolerances, lubrication and load and speed requirements against the exact manufacturer variant and equipment specification.
C3 describes internal clearance; it is not a quality grade. Closure suffixes differ between manufacturers. Do not infer the complete configuration from the base number alone.
Preserve prefixes, suffixes, slashes and hyphens when searching. Missing information remains unknown until sourced.
