  • Publication number: 20250389298
    Abstract: An elastomeric bushing comprises an inner sleeve including a first end face and an opposite second end face. A bearing circumscribes the inner sleeve. An elastomer is disposed around and directly engages the bearing. The elastomer includes a first seal gland. An outer sleeve is disposed around the bearing and the elastomer. The outer sleeve is spaced apart from the inner sleeve and directly engages the elastomer. A one-piece monolithic first cap includes an end wall and a side wall surrounding a portion of the inner sleeve and a portion of the bearing. The end wall radially inwardly extends from the sidewall and overlaps the first end face of the inner sleeve. The stepped sidewall includes an inner surface positioned in engagement with the first seal gland.

  • Patent number: 12297883
    Abstract: An elastomeric bushing comprises an inner sleeve including a first end face and an opposite second end face. An elastomeric bumper is disposed around and directly engages the inner sleeve. The elastomeric bumper includes an annular void. An outer sleeve is disposed around the inner sleeve and the elastomeric bumper, spaced apart from the inner sleeve, and directly engages the elastomeric bumper. A one-piece monolithic ferrule includes a cylindrical sidewall surrounding a portion of the inner sleeve, an end wall, and a collar. The end wall radially inwardly extends from the side wall and overlaps the first end face of the inner sleeve. The collar has an outer surface positioned within the outer sleeve and within the annular void to limit the radial extent of relative movement between the inner and outer sleeves.

  • Patent number: 11815149
    Abstract: An elastomeric bushing comprises an inner sleeve, an elastomeric bumper disposed around and directly engaging the inner sleeve, and an outer sleeve disposed around the inner sleeve and the elastomeric bumper. The outer sleeve is spaced apart from the inner sleeve and directly engages the elastomeric bumper. The inner sleeve includes a first protrusion and a second protrusion axially spaced apart from one another. The outer sleeve includes a radially inwardly extending indentation axially positioned between the first protrusion and the second protrusion. The indentation traps a first portion of the elastomeric bumper between the first protrusion and a first surface of the indentation and also traps a second portion of the elastomeric bumper between the second protrusion and a second surface of the indentation.
