ACL – 5M7788H-.25 – Main Bearing Set – +.25 Size

A 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 dissipation.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 ofhydrodynamicoil film.Bearing eccentricity is the gradual reduction in wall thickness between the crown and parting line.
