Since 1960 the KING RACING company has designed and manufactured high performance/quality bearings. Beyond high-performance production machines, King Racing relies on simulation software to analyze the thermodynamics, dynamics and elasto-hydrodynamics of their bearings. KING RACING tri-metal bearings are produced in pMax Black, a tri-metal alloy 24% stronger than all existing tri-metal bearings.

KING RACING bearings are made up of 3 to 4 layers (depending on applications):

Exterior: steel Intermediate: leaded bronze Interior: babbitt with a high copper content Anti-friction Coating containing lubricant and ceramic additives
