A quick release pillow block bearing assembly has end pieces, a center bearing housing carrying a bearing, and quick release pins for retaining the bearing housing with the end pieces. The invention enables replacement and or repair of the bearing and its counterparts easily, efficiently, and less often. The user need only remove the quick release pins remove the bearing housing and thereby gain access to the housing, which also provides access to the bearing/shaft and counterparts. Upon removal of the quick release pins, the center housing may be removed from the structure, while the end pieces stay in place, allowing one to remove and install the bearing quickly. It also enables removal of the shaft in seconds, thus permitting easy and quick replacement of worn sections of the bearing.

The present invention relates to a pressure roller bearing for a pallet car of a pelletizing machine. The bearing includes an external annular race having: an exterior surface for reversible mating engagement with a tooth gap of a wheel, a pair of sidewalls defining ends of the bearing, wherein the radial diameter of the exterior surface at a center portion in the axial direction is greater than the radial diameter of the exterior surface at the ends of the bearing, and an interior annular groove; an internal annular race defining a hole therethrough for receiving an axle, and having an exterior annular groove; and a plurality of rolling cylindrical members located in an interior space defined by the interior annular groove and the exterior annular groove when the internal annular race is received by the external annular race.

A bearing body is provided. The bearing body includes first and second support surfaces inclined so as to slope upward from a side on the imaginary central vertical plane passing through an axis of a rotating shaft to be supported toward one and the other outer sides in the width direction of the rotating shaft. First and second transitional regions that respectively make transitions from the first and second support surfaces to a first and end surface of the bearing body on one side in the axial direction of the rotating shaft have a curved shape projecting obliquely upward such that an orientation of a normal line changes from a perpendicular direction to a parallel direction with respect to the axis of the rotating shaft toward one side from the other side in the axial direction of the rotating shaft.

A method of manufacturing a bottom bearing may include forming a first half-cylinder and a second half-cylinder, the first half-cylinder including a first shoulder and a first inside surface and the second half-cylinder including a second shoulder and a second inside surface. The first shoulder and second shoulder are configured to bear the weight of a vertical shaft by exerting an upward force on a sleeve in mechanical communication with the vertical shaft.

A bearing system that accepts a journal of a roll includes a housing defining a cavity and having a forward wall that defines an opening into the cavity, the opening configured to accept the journal through the opening and into the cavity. A sleeve is positioned within the cavity of the housing, the sleeve configured to surround the end of the journal. A first seal is positioned within the cavity of the housing adjacent to the forward wall of the housing, the first seal having an engagement surface. A second seal is positioned within the cavity of the housing and operably connected to the sleeve, the second seal having an engagement surface in contact with the engagement surface of the first seal.

This invention provides an idler for use in conveyor systems and associated shaft and support structure that reduces the potential for infiltration of contaminants into the bearing assemblies at the opposing ends of the shaft. By use of stampings, co-molded polymer with sealed metal end caps, press-fit end shafts and stamped-metal support structures a more contamination-resistant and efficiently constructed idler assembly is provided. A hollow shaft center section can be used. The polymer defines at least three sealing structures. The shaft defines a multi-piece unit, with the end shafts press-fit onto the center shaft section and held in place by the bearing subassemblies—affixed to the idler sleeve. The support framework includes three stamped and/or cut, and folded sheet metal pieces—a center section with a pair of opposing central risers that engage end shafts, and two opposing, separately attached, end risers, that engage outermost idler end shafts.

To provide a ball transfer and a seal member for a ball transfer, a seal member is employed which is characterized in that it has a seal member employing pile fiber that, at a ball transfer having a main body which has a socket, an inner surface of which is a hemispherical concave surface, a plurality of ball bearings arranged at the main exterior socket, a primary ball, diameter of which is greater than that of said ball bearings and which is rotatably supported by the socket by way of the ball bearings, and a housing-like case which surrounds the main body socket and rotatably supports the ball bearings and the primary ball at a bearing portion thereof and which has a hole from which a portion of the primary ball is made to protrude at an upper surface of the primary ball socket.

A modular roller device to facilitate horizontal displacement of objects and materials, including large, heavy, or bulky objects and materials comprising a frame constructed of at least one formed rod, a first rolling member rotatably mounted to a first support arm, and a second rolling member rotatably mounted to a second support arm, wherein the first rolling member may be arranged in a generally parallel orientation relative to the second rolling member. The frame may comprise at least one extending section, and the opposing first and second support arms may be coupled thereto. The at least one extending section may comprise a longitudinally extending section and/or a diagonally extending section. The modular roller device may further comprise at least one secondary extending section. The modularly roller devices can be further combined to a form a system to facilitate the horizontal displacement of objects and materials.

The roller comprises a covering layer made of a fibre composite material and a cylindrical roller main body having an outer first lateral surface, a first end section and a second end section. The covering layer completely surrounds the first lateral surface in the circumferential direction. A first edge region of the covering layer extends beyond the first end section, is folded over inwards and is fixed in relation to the roller main body. In a crosslapper, the roller can be provided as a deflection roller of a conveyor belt. In a carding machine, the roller can be provided as an engagement roller for engagement with fibre material.

An end cap assembly for a conveyor roll includes an end cap configured to fit over an end of the conveyor roll, and the end cap has an opening. The end cap assembly further includes a spring member configured to be positioned between the end of the conveyor roll and the end cap, and a fastener that is insertable into the opening of the end cap. The fastener is configured to cooperate with the spring member to apply a retention force to assist in retaining the end cap on the conveyor roll.
