  • Publication number: 20190168306
    Abstract: A cam follower roller device comprising a tappet body extending along a longitudinal axis and defining a tappet bore, and a bearing assembly mounted in the tappet bore. The bearing assembly includes a pin centered on a pin transverse axis (the transverse axis is perpendicular to the longitudinal axis), and a roller rotatably mounted on the pin. The tappet body is made by a metal injection molding process including successive steps of mixing a metal powder with a thermoplastic binder, forming a part by injection of the mixed powder in a closed die, debinding the formed part in a furnace, sintering to densify the part, and quenching to set a tappet body hardness, to improve wear resistance and fatigue life.

  • Publication number: 20180149203
    Abstract: A sealing device is configured to be mounted between two elements rotatable relative to one another, notably rings of a rolling bearing. The sealing device provides a seal and a shield adapted to be coupled to one of the two elements and arranged laterally to the seal to define a gap therebetween. The seal includes at least one sealing lip that bears against a radial portion of the shield. The thickness of the sealing lip gradually increases from a base portion of the lip towards its free end which is in friction contact with the shield. The thickness (t1) of the base portion of the sealing lip and the thickness (t2) of the free end of the lip are defined by: t1?t2 and 0.6?(t1+t2)3?1.2.
