Amendment October 30, 2002 The scope of claims for utility model registration is amended as follows.

[Claims for Utility Model Registration] 1. A utility model installed between a circumferential groove-like constriction formed at the end of a roll of a rolling mill and a chock divided into upper and lower parts along the axis of the roll. In a split type bearing for a rolling mill that supports the end of a roll, the bearing has one inner ring formed with a double-row raceway and a single-row raceway, and the front side of the bearing is formed with a spacer. A compound comprising a pair of outer rings assembled together, a cage interposed between the inner ring and the outer ring, and tapered rollers that are held by the cage and roll between the inner and outer rings. It is a row inward tapered roller bearing, and the inner ring, outer ring, cage, and spacer are each divided into two along the roll axis to form semicircular halves, and the two halves are each divided into two semicircular halves. A split type bearing for a rolling mill, characterized in that each half of the inner ring is fastened to the constriction of the roll by a fastening ring wound around the outer periphery of both axial ends of the inner ring half. 2. The split type bearing for a rolling mill according to claim 1, wherein an engaging portion is formed between the pair of outer rings and the spacer to prevent at least the spacer from moving radially inward with respect to the outer ring. 3. The outer ring and the spacer are divided into upper and lower halves along the roll axis, and the upper half of the outer ring and the spacer are engaged with each other, and the upper chock of the chock is divided into the upper and lower halves. 3. The split bearing for a rolling mill according to claim 2, wherein the split bearing is integrally attached to the bearing. 4 A collar for positioning the inner ring in the axial direction with respect to the roll is interposed between one axial end face of the inner ring and one side face of the neck part of the roll. Claim 1 or 3 further comprising a position adjustment bolt for adjusting the relative position in the axial direction between the collar and the collar.
The described split bearing for a rolling mill.

[Claims for Utility Model Registration] 1. A utility model installed between a circumferential groove-like constriction formed at the end of a roll of a rolling mill and a chock divided into upper and lower parts along the axis of the roll. In a split type bearing for a rolling mill that supports the end of a roll, the bearing has one inner ring formed with a double-row raceway and a single-row raceway, and the front side of the bearing is formed with a spacer. A compound comprising a pair of outer rings assembled together, a cage interposed between the inner ring and the outer ring, and tapered rollers that are held by the cage and roll between the inner and outer rings. It is a row inward tapered roller bearing, and the inner ring, outer ring, cage, and spacer are each divided into two along the roll axis to form semicircular halves, and the two halves are each divided into two semicircular halves. A split type bearing for a rolling mill, characterized in that each half of the inner ring is fastened to the constriction of the roll by a fastening ring wound around the outer periphery of both axial ends of the inner ring half. 2. The split type bearing for a rolling mill according to claim 1, wherein an engaging portion is formed between the pair of outer rings and the spacer to prevent at least the spacer from moving radially inward with respect to the outer ring. 3. The outer ring and the spacer are divided into upper and lower halves along the roll axis, and the upper half of the outer ring and the spacer are engaged with each other, and the upper chock of the chock is divided into the upper and lower halves. 3. The split bearing for a rolling mill according to claim 2, wherein the split bearing is integrally attached to the bearing. 4 A collar for positioning the inner ring in the axial direction with respect to the roll is interposed between one axial end surface of the inner ring and one side of the neck of the roll. 4. The split type bearing for a rolling mill according to claim 1, further comprising a position adjustment bolt for adjusting the relative position in the axial direction between the bearing and the collar.
