His innovative approach has led to the development of a unique bearing halfshell that enhances engine performance.

Latest Patents

Durval Bencini holds a patent for a sleeve bearing that features a halfshell designed for internal combustion engine connecting rods. The inner surface of this bearing has a substantially constant radius of curvature from a central plane of symmetry to two portions located on each side of this plane. The design includes a radial plane that forms an acute angle with the bearing parting plane. The remaining end portions of the inner surface are defined by surfaces with extra relief, allowing the bearing thickness to decrease gradually away from the central plane. This innovative design creates two chambers in the end portions, ensuring a stable film of oil between the bearing halfshell and the corresponding shaft, which reduces the operating temperature of the bearing. The elliptic contour of the eccentric surface provides excellent performance.
