Abstract
The bearing provides an outer ring, an inner ring, at least one seal to one of the rings and cooperating with the other ring, and at least one sealing flange. The sealing flange includes a fixing portion to fix the flange to the other ring, an end portion and a connecting portion to connect the fixing portion and end portion. The end portion of the flange is curved and disposed axially facing the connecting portion. The curved end portion and connecting portion define an annular space that open radially towards the other ring. The curved end portion is mounted axially in contact against an outer lateral face of the seal.
Claims18
A bearing comprising:
- an outer ring,
- an inner ring,
- at least one seal fixed to one of the rings and cooperating with the other ring, and at least one sealing flange providing a fixing portion to fix the at least one sealing flange to the other ring,
- the at least one sealing flange having an end portion and a connecting portion to connect the fixing portion and the end portion, wherein
- the end portion of the at least one sealing flange is curved and disposed axially facing the connecting portion, wherein
- the end portion and the connecting portion define an annular space that opens radially towards the other ring, wherein
- the end portion is configured to axially contact against an outer lateral face of the at least one seal, and
- wherein the at least one sealing flange is at least elastically deformable in an axial direction, at least the connecting portion of the at least one sealing flange being axially deformed towards an exterior of bearing due to axial contact between the end portion and the at least one seal.
A bearing comprising:
- an outer ring,
- an inner ring,
- at least one seal fixed to one of the rings and cooperating with the other ring, and at least one sealing flange providing a fixing portion to fix the at least one sealing flange to the other ring,
- the at least one sealing flange having an end portion and a connecting portion to connect the fixing portion and the end portion, wherein
- the end portion of the at least one sealing flange is curved and disposed axially facing the connecting portion, wherein
- the end portion and the connecting portion define an annular space that opens radially towards the other ring, wherein
- the end portion is configured to axially contact against an outer lateral face of the at least one seal, and
- wherein the end portion of the at least one sealing flange provides at least one through hole formed axially through the end portion to allow the diffusion of lubricant provided in the annular space towards a location where the end portion axially contacts with the at least one seal.
A bearing comprising:
- an outer ring,
- an inner ring,
- at least one seal fixed to one of the rings and cooperating with the other ring, and at least one sealing flange providing a fixing portion to fix the at least one sealing flange to the other ring,
- the at least one sealing flange having an end portion and a connecting portion to connect the fixing portion and the end portion, wherein
- the end portion of the at least one sealing flange is curved and disposed axially facing the connecting portion, wherein
- the end portion and the connecting portion define an annular space that opens radially towards the other ring, wherein
- the end portion is configured to axially contact against an outer lateral face of the at least one seal, and
- wherein the end portion of the at least one sealing flange has a corrugated shape.
