Bearing Search

Problem It Solves

During maintenance, procurement, and design, engineers often need to read a short string of letters and digits to determine bearing inner diameter, outer diameter, width, rolling-element type, sealing form, and clearance grade. Similar suffixes can change fit or compatibility, while SKF, NSK, and FAG use different coding habits. Relying on memory or manual catalogs can lead to misread replacements that mismatch size, load, or speed.

How the Skill Works

Bearing Search treats bearing models and manufacturer information as queryable objects. It usually covers four tasks:
- Model search: given a model number, return dimensions, bearing type, sealing forms such as open/ZZ/2RS, clearance, and accuracy grade.
- Brand search: look up a manufacturer's product lines, main application areas, and technical characteristics.
- Code parsing: split prefixes, base designations, and suffixes, then explain ISO designations, cross-brand equivalents, and suffix meanings.
- Selection guidance: based on radial, axial, or composite loads, speed, temperature, corrosion, contamination, and installation space, suggest the most relevant directions to check first.
Reference data lives in data/models/ and data/brands/, with coding and brand rules in references/model-codes.md and references/brands.md.

Boundaries

It is suited for model lookup, code interpretation, and preliminary selection. It is not a supplier price source, stock system, life-calculation tool, or final engineering approval. For extreme conditions, safety-critical components, special materials, or custom replacements, rely on vendor catalogs, test data, installation calculations, and site constraints.
