Metallurgical and engineering innovations that provide Race Series bearings with remarkable endurance.
High Strength Steel Backing
Higher tensile strength of steel alloy improves rod bearing strength and retention. Increased crush improves bearing retention from higher radial contact pressures, and also improves heat dissapation.
Bearing eccentricity is the gradual reduction in wall thickness between the crown and parting line. This enhanced engineering feature allows for compensation for bore distortion and assists in the formation of hydrodynamic oil film.
Extended Oil Grooves and Tapered Groove Run-Out
Main bearing grooved uppers with matching groove lowers provide for less interuption to big end oil supply. Tapered groove runÃ¢€â€œout smooths big end supply cutoff and avoids pressure pulsing and cavitation.
