Abstract: Provided is a roll unit to be dipped in a surface treatment liquid of a copper foil, wherein a bearing box for housing a roil shaft is configured from two bearing boxes that are divisible, one of the bearing boxes is configured from a roll-side bearing box arranged on a roll main body-side and the other bearing box is configured from a shaft end-side bearing box arranged on the shaft end-side of the roll, a shaft sleeve covering an outer periphery of the roll shaft is provided in the roll-side bearing box and an oil seal is provided along an outer periphery of the shaft sleeve, and a bearing for rotatably supporting the shaft is disposed in the shaft end-side bearing box.

Abstract: An oil film bearing assembly rotatably supports the neck of a roll in a rolling mill. The bearing assembly comprises a housing containing a sleeve bearing and a thrust bearing. A circular lock assembly coacts with the thrust bearing to axially retain the bearing assembly on the roll neck. The lock assembly is axially received on and is rotatable into and out of mechanical interengagement with the roll neck. First bearing elements are carried by and project inwardly from the lock assembly to contact a surface of the roll neck at a first location, and second bearing elements project inwardly from the housing to contact an outer surface of the lock assembly at a second location spaced axially from the first location.

Abstract: The roller can be suitably used for a guide section of a moving unit capable of moving a heavy matter without enormously increasing rigidity of a rail and is capable of reducing weight and production cost of the moving unit. The roller comprises: a tubular core having an outer circumferential face, in which a groove section is formed; and a resin coat section continuously coating the outer circumferential face of the tubular core, an inner face of the groove section, both ends of the tubular core and at least parts of an inner circumferential face thereof.

Abstract: A seat track assembly includes a first track having a mounting wall and first and second spaced apart side walls extending from the mounting wall, and a second track having a base flange and first and second spaced apart side flanges extending from the base flange. The side walls and the side flanges each have a pair of flat surfaces which cooperate to define a pair of load transmission channels. The load transmission channels are preferably square-shaped and oriented at 45 degrees. Load transmission elements are positioned in the load transmission channels. At least one of the first and second tracks produce an interference with the load transmission elements so that at least one of the first and second tracks is resiliently deflected by the load transmission elements to bias the load transmission elements into engagement with each of the four flat surfaces.

Abstract: A stud type track roller bearing includes a shaft provided with a flange, an annular side plate located in an opposed relationship and fixedly attached to the shaft, a ring fitted onto the flange, a plurality of rollers interposed between the ring and the shaft, a plurality of balls interposed between the ring and the flange also between the ring and the side plate, a retainer for retaining the rollers in position. The rollers mainly serve to support the load in the radial direction and the balls mainly serve to support the load in the axial direction.

Abstract: A hydroextractor which is mainly useful to carry out the industrial dedusting, rinsing and centrifuging of rugs, comprises a hollow cylindrical body (2) having holes in its surface. The cylindrical body is rotated around its longitudinal axis bya drive morot (7) connected to a shaft (6) connected to the closed end of the cylindrical body. The rotation of the cylindrical body is guided by pairs of rollers (9) placed on its periphery and which rotate in individual annular roller paths (8). The rollers are mounted by supports (10) and, in turn, support the cylindrical body.

Abstract: A roller bearing for supporting pipes subject to thermal expansion which includes a mounting defined by a base plate having opposite side walls bent into generally converging relationship to each other in a direction away from the base plate, a pillow block supported from the base plate, a roller between each side wall and the pillow block, a bearing pin rotatably supporting each roller, and each bearing pin being in spanning relationship between the pillow block and an associated one of the side walls.

Abstract: Positions of marker images included in two images obtained by a digital radiography system are detected by a marker position detecting section. The marker image intervals in each image are calculated by an extension rate correcting section in accordance with the detected positions of the marker images. Reduction/extension for one image is perfomed in accordance with the extension rate of the image obtained by a ratio of the calculated marker image intervals, thereby coinciding extension rates of two images.
