Abstract
Seal assemblies, bearing assemblies, and gaskets and their components can be used as pre-packaged systems or assemblies inside a can housing. Gaskets or washers to restrict flow and gaskets or washers with memory lips to operate as sealing lips can be included to increase the number of sealing points inside the pre-packaged systems. In a pre-packaged configuration, the cylinder can be a straight cylinder, a stepped cylinder, or a split cylinder. Bearing assemblies can be pre-packaged with the sealing assemblies.
Claims33
A cartridge seal and bearing system comprising:
- a can housing having a body having a wall with an interior surface defining a bore having a first end and a second end, the first end having a retaining wall or a retaining disc;
- a structural component having a body located in the bore of the can housing;
- a first seal element comprising an inside flange, an outside flange, and a center channel section located between the inside and outside flanges, the outside flange of the first seal element being pressed against the interior surface of the can housing by the structural component;
- a second seal element comprising an inside flange, an outside flange, and a center channel section located between the inside and outside flanges, the outside flange of the second seal element being pressed against the interior surface of the can housing by the structural component;
- a bearing assembly comprising an inner ring, an outer ring, and a plurality of rolling elements between the inner and outer rings, said bearing assembly located in the bore and closer to the second seal element than the first seal element;
- wherein the outer ring is in a loose fit arrangement inside the bore when initially assembled or the inner ring is in a loose fit arrangement with a shaft when the shaft is inserted in through the inner ring;
- and
- wherein the structural component has a flange stub, and wherein the flange stub is spaced from the interior surface of the can housing.

A method of assembling a pre-packaged cartridge and bearing system comprising:
- providing a can housing having a body having a wall with an interior surface defining a bore having a first end and a second end, the first end having a retaining wall or a retaining disc;
- placing a seal assembly inside the bore, the seal assembly comprising:
- a structural component having a body located in the bore of the can housing;
- a first seal element comprising an inside flange, an outside flange, and a center channel section located between the inside and outside flanges, the outside flange of the first seal element being pressed against the interior surface of the can housing by the structural component;
- a second seal element comprising an inside flange, an outside flange, and a center channel section located between the inside and outside flanges, the outside flange of the second seal element being pressed against the interior surface of the can housing by the structural component;
- placing a bearing assembly inside the bore, the bearing assembly comprising an inner ring, an outer ring, and a plurality of rolling elements between the inner and outer rings, said bearing assembly located in the bore and closer to the second seal element than the first seal element;
- wherein the outer ring is in a loose fit arrangement inside the bore when initially assembled inside the bore or the inner ring is in a loose fit arrangement with a shaft when the shaft is inserted in through the inner ring;
- and
- wherein the structural component has a flange stub, and wherein the flange stub is spaced from the interior surface of the can housing.
