Sintered iron bearings (or bushings) are powder-metal components highly valued for their self-lubricating properties. Manufactured by compacting iron powder in a die and heating it to fuse the particles, the resulting porous structure is impregnated with lubricating oil, creating a maintenance-free, friction-reducing bearing.
Compared with bronze bearings, iron bearings provide higher load capacity and lower material costs.
