Latest Patents

Zembutsu holds a patent for a tapered roller bearing, which features a holder made of resin. This design includes a first gap between the axially inner end surface of a small-diameter-side annular part and the small-diameter-side end surfaces of the tapered rollers. Additionally, there is a second gap between the axially inner end surface of a large-diameter-side annular part and the large-diameter-side end surfaces of the tapered rollers. The holder is designed to move within a prescribed range along the axial direction. Notably, the surface of the axially inner end surface of the large-diameter-side annular part is rough, and it is equipped with one or more grooves that serve as oil-holding parts to retain lubricating oil. The ends of these grooves are positioned to come into contact with the tapered rollers, enhancing the bearing's performance.
