Practical engineering tools, identification guides and reference information for maintenance teams, engineers and industrial buyers.
Engineering information without the guesswork
Search by product type, reference or measurement. Each tool is designed to help engineers identify an item and move directly towards a quotation or replacement.
Popular maintenance resources
Start with the marking where it is legible. If it is missing or damaged, take careful measurements and include clear photographs before ordering.
Bearing identification and supply
Use the complete designation where possible. For an unmarked bearing, record the bore, outside diameter and width, then note the bearing type, seals or shields, internal clearance and application.
Local supply support: Manchester and Tameside.
Retaining-ring identification
First confirm whether the ring fits an external shaft or an internal bore. Then compare the nominal diameter, ring thickness, free diameter and groove dimensions with current manufacturer data.
