Application scenarios include imported-equipment maintenance, supply changes and spare-parts planning. Prepare the original brand and complete designation, suffixes, pairing marks, parameter documents, installation drawings and operating conditions. This guide supports technical comparison and does not automatically declare interchangeability.
Build the original designation document set
Provide the original brand and complete designation, marking or packaging photographs, suffixes, pairing marks and parameter documents. State whether the request is for a new design, maintenance replacement or long-term spare-parts planning, including special equipment-manufacturer requirements.
Keep document revisions, units and field names. Suffix and structure conventions can differ between brands; do not remove suffixes and compare only basic designations.
Compare more than envelope dimensions
Equal dimensions do not establish interchangeability. Begin with bore, outside diameter and applicable width fields, then organise structure, sealing, cage, accuracy, clearance or preload, pairing and installation-direction information.
Keep load and speed units and conditions consistent; compare grease and oil values separately. Missing original data is not guessed or filled from a similar designation or another brand.
Include the equipment requirements
Describe the equipment, bearing position, speed range, load directions, lubrication and environment. Provide shaft-shoulder, housing, cover and locking drawings. For paired or combined arrangements, describe the whole bearing group.
List changes to installation, lubrication or maintenance as separate items. A catalogue comparison between individual bearings is not proof that an entire equipment modification is suitable.
Document the assessment outcome
The comparison should identify original and candidate designations, field differences, equipment restrictions and required verification. Explain the scope of significant differences and retain document revisions and technical discussion records.
Application conclusions depend on equipment requirements and verification results. This website does not automatically issue cross-brand interchangeability conclusions or unsupported claims about performance similarity, cost savings or life.
