Lead-Free Soft Bearing Wire 4.8 mm

Thermal Spray Bearing Wire for Surface Restoration

Soft bearing wires are used in thermal spray applications where a sacrificial, conformable, or low-friction surface is needed on rotating components. The lead-free formulation addresses growing regulatory and workplace safety requirements while maintaining the functional properties expected from a bearing overlay—good embeddability for dirt and debris, low friction against mating surfaces, and sufficient adhesion to the substrate when applied with proper surface preparation.

At 4.8 mm diameter, this wire is compatible with standard arc spray and larger flame spray systems. The diameter provides a balance between deposition rate and spray control, making it suitable for both manual and automated spray operations on bearing journals, thrust faces, and similar cylindrical surfaces.

Pack Options and Handling

SPA2Z offers this wire in spool and coil pack configurations to match your equipment and throughput requirements:

• 15 kg spool — Compact option for lower-volume shops or trial applications
• 20 kg spool — Standard production size for regular bearing repair work
• 25 kg spool — Higher-volume option for continuous spray operations
• Coil pack — Alternative format for systems that prefer coil-fed wire

Proper storage in dry conditions is recommended to maintain wire surface quality and prevent oxidation that could affect spray consistency.

Application Considerations

This wire is typically applied to bearing journals, thrust collars, and other rotating surfaces where a soft, embeddable layer is required. The lead-free composition makes it suitable for applications where lead content is restricted by regulation, customer specification, or internal environmental policy. Common industries using this type of wire include pump and compressor repair, marine shaft restoration, industrial gearbox overhaul, and general rotating equipment maintenance.

Surface preparation by grit blasting is essential before spraying to achieve proper bond strength. The wire is then sprayed to the required thickness and finish-machined to final dimensions. Process parameters—including spray distance, voltage, amperage, and atomizing air pressure—depend on the specific alloy grade and spray system being used.
