Lead-Free Soft Bearing Wire 2.5 mm

Why Choose a Lead-Free Bearing Wire?

Traditional bearing alloys often contain lead for conformability, but tightening environmental regulations and operator safety requirements are driving a shift toward lead-free alternatives. A well-formulated lead-free soft bearing wire can match or exceed the performance of leaded grades in many thermal spray applications, particularly where oil-lubricated sliding wear is the primary concern.

Key advantages of a lead-free bearing wire include:

• Regulatory compliance: Meets RoHS and similar directives that restrict lead in industrial materials.
• Operator safety: Reduces airborne lead exposure during the spray process, simplifying workplace controls.
• Waste handling: Spent overspray and grinding dust are classified as non-hazardous in most jurisdictions, lowering disposal costs.
• Performance parity: Modern lead-free bearing alloys are designed to offer comparable embeddability, conformability, and friction characteristics.

Thermal Spray Process Compatibility

This 2.5 mm diameter wire is drawn to tight dimensional tolerances, ensuring consistent feedability through both arc spray and combustion flame spray systems. The 2.5 mm size is a widely used diameter that balances deposition rate with coating density. Process fit should be confirmed on enquiry, as the optimal spray parameters—current, voltage, standoff distance, and atomizing gas pressure—depend on the specific alloy grade and the substrate material.

Typical spray processes considered for this wire include:

• Twin-wire arc spray: High deposition rates for large bearing areas and thick overlays.
• Combustion flame spray: Suitable for smaller components or where lower capital equipment cost is a priority.

Pack Options and Handling

Consistent wire payoff is critical for coating quality. This wire is supplied on precision-wound spools in 15 kg, 20 kg, and 25 kg sizes. Coil packs are also available for users with de-coiling equipment. Each spool is protected against moisture and contamination during storage and transit. We recommend storing wire in a dry, covered area and using it within the shelf life advised for the specific alloy grade.
