Abstract
A roller structure including a cylindrical casing having an outer wear surface and an inner surface provided by a bore extending through the cylindrical casing. At least one anti-friction bearing is positioned within the bore in contact with the inside surface of the cylindrical casing. The anti-friction bearing includes a solid lubricant. In one embodiment, the roller structure is a roller turn roller and is a component of a guide for a turn of a conveyor system, wherein the outer wear surface is for contacting the chain of the conveyer system. A method of lubricating a roller structure is also provided.
Claims14
A roller structure comprising:
- a cylindrical casing having an outer wear surface and an inner surface provided by a bore extending through the cylindrical casing;
- at least a first and second anti-friction bearing positioned within the bore in contact with the inside surface of the cylindrical casing, wherein the first anti-friction bearing that is proximate to a first opening to the bore and the second anti-friction bearing is proximate to a second opening to the bore;
- a first bushing proximate to a first side of the casing, the first bushing having a first flange and a first cylindrical body, wherein the first flange is in contact with an outer sidewall face of the inner ring of the first anti-friction bearing and the first cylindrical body is in contact with a bore face of the first anti-friction bearing, wherein the first cylindrical body has a first length;
- a second bushing proximate to a second side of the casing, the second bushing having a second flange and a second cylindrical body having a second length that is greater than the first length, wherein the second flange is in contact with the outer sidewall face of the inner ring of the second anti-friction bearing and the second cylindrical body is in contact with the bore face of the second anti-friction bearing and the bore face of the first anti-friction bearing;
- and
- a spacer between the first anti-friction bearing and the second anti-friction bearing, wherein the spacer is in contact with the inner sidewall face of the inner ring of the first anti-friction bearing and the inner sidewall face of the inner ring of the second anti-friction bearing.
