Claims
- 1. A support housing for a bearing insert, the bearing insert including an inner race, an outer race and a plurality of bearing elements disposed therebetween, the support housing comprising:a bearing insert support portion configured to receive and support the bearing insert; and an attachment portion integral with the bearing insert support portion, the attachment portion including a plurality of apertures configured to receive fasteners for securing the support housing to a machine support surface, and a single, substantially continuous uniplanar mounting surface; wherein the bearing insert support portion and the attachment portion comprise an admixture of a moldable polymeric material and an antimicrobial agent for inhibiting growth of microorganisms, wherein the admixture further includes a fiberglass reinforcing component.
- 2. The support housing of claim 1, wherein the attachment portion forms a base on which the support housing is mounted when placed in service.
- 3. The support housing of claim 1, wherein the moldable polymeric material comprises a structural foam.
- 4. The support housing of claim 3, wherein the housing forms a substantially closed skin on outer surfaces thereof and a porous structure within interior regions bounded by the skin.
- 5. A support housing for a bearing, the housing comprising:a body made of a moldable plastic material and forming a bearing support surface for receiving a bearing insert and a mounting surface for securing the housing to a machine surface, outer surfaces of the housing being exposed and the mounting surface being supported on the machine surface when the housing is mounted thereon, the body including an antimicrobial agent, the antimicrobial agent inhibiting growth of microbes on the outer surfaces and on the mounting surface, wherein the body includes boundary regions having a first densities adjacent to the outer and mounting surfaces of the housing and an internal regions having second densities between the boundary regions, the first densities being greater than the second densities.
- 6. A support housing for a bearing, the housing comprising:a body made of a moldable plastic material and forming a bearing support surface for receiving a bearing insert and a mounting surface for securing the housing to a machine surface, outer surfaces of the housing being exposed and the mounting surface being supported on the machine surface when the housing is mounted thereon, the body including an antimicrobial agent, the antimicrobial agent inhibiting growth of microbes on the outer surfaces and on the mounting surface, wherein the body comprises an admixture of a moldable plastic material and a fibrous reinforcement material.
- 7. The support housing of claim 6, wherein the body includes boundary regions having a first densities adjacent to the outer and mounting surfaces of the housing and an internal regions having second densities between the boundary regions, the first densities being greater than the second densities.
- 8. The support housing of claim 6, wherein the body is a unitary structure made of an admixture of a moldable plastic material and the antimicrobial agent.
- 9. The support housing of claim 6, wherein the body is a structural foam including a substantially closed skin on the outer surfaces and the mounting surface and a porous interior region within the skin.
- 10. The support housing of claim 6, wherein the mounting surface of the body is substantially planar and is substantially flush with the machine surface when the support housing is mounted thereon.
- 11. The support housing of claim 6, including apertures extending through portions of the body and transverse to the mounting surface, each of the apertures including a metallic reinforcing insert for receiving a fastener for securing the housing to a machine surface.
- 12. The support housing of claim 6, wherein the bearing support surface is formed by an inner periphery of an aperture extending substantially transverse to the mounting surface.
- 13. A support housing for a bearing insert, the bearing insert including an inner race, an outer race and a plurality of bearing elements disposed therebetween, the support housing comprising:a bearing insert support portion configured to receive and support the bearing insert; and an attachment portion integral with the bearing insert support portion, the attachment portion including a plurality of apertures configured to receive fasteners for securing the support housing to a machine support surface; wherein the bearing insert support portion and the attachment portion comprise an admixture of a moldable structural foam polymeric material and an antimicrobial agent for inhibiting growth of microorganisms, the housing forming a substantially closed skin on outer surfaces thereof and a porous structure within interior regions bounded by the skin.
- 14. The support housing of claim 13, wherein the structural foam has a varying density from the skin to the interior regions.
- 15. The support housing of claim 13, wherein the attachment portion forms a base on which the support housing is mounted when placed in service, and wherein the base includes a base mounting surface extending substantially in a plane and coextensive with the base.
- 16. The support housing of claim 13, wherein the admixture further includes a fibrous reinforcing material.
- 17. The support housing of claim 16, wherein the fibrous reinforcing material includes a fiberglass reinforcing component.
- 18. The support housing of claim 13, wherein the mounting portion includes a substantially planar mounting surface for securing the housing to a machine surface.
- 19. The support housing of claim 18, wherein the mounting surface is substantially flush with the machine surface when the support housing is mounted thereon.
