SOLUTION: In a rolling bearing A having an aligning ring, rollers 3 are arranged between an inner ring 1 and an outer ring 2, and a spherical part 21 of the outer ring 2 is fitted to an aligning ring 4. The aligning ring 4 has a spherical part 4a on its inner periphery 4a for supporting the outer ring 2 in an aligning manner under a state arranged inside a bearing box. The aligning ring 4, is divided into two along a plane perpendicular to an axis at a center portion in an axial direction. Cutouts 43 for application of knock pins are formed on outer peripheral side ends of a pair of circular members 41, 42 composing the aligning ring 4. Relative rotation of the outer ring 2 and the aligning ring 4 is regulated by means of the knock pins formed on specified portions on a circumference.

摘要： PURPOSE:To prevent the generation of rust in the projecting parts at both ends of roll shaft by force-fitting a sleeve made of a corrosion resistant material on the outer periphery of the projecting parts at both ends of roll shaft. CONSTITUTION:An outer jacket 2 is supported with the roll shaft 1 on the stationary side of a back-up roll of a rolling mill through plural rollers 3. The corrosion resistant sleeve 4 is force-fitted on the outer periphery of the projecting parts 1a at both ends of the roll shaft 1. Positioning hols 4a, 1b are coaxially formed on the sleeve 4 and the roll shaft 1 in a radial direction and a locking pin 6 for the sleeve 4 is projectingly provided on a lower supporting member 5. When the roll shaft 1 is placed on the lower supporting member 5, the locking pin 6 is fit. An upper supporting member 7 is placed and integrally fixed with a bolt 8. Cooling water is poured on the whole during operation, but the projecting parts 1 at both ends of the roll shaft 1 is not rusted because the sleeve 4 is force-fitted.

摘要： PROBLEM TO BE SOLVED: To improve the strength to the axial load of a flange 3a mounted on an inside part of an outer ring 3 of a double row cylindrical roller bearing 1.
SOLUTION: The inner diameter part of the outer ring 3 is provided with raceway faces 3b, 3c of several roller rows, the flange 3a is mounted radially inward between the raceway faces 3b, 3c adjacent to each other in the axial direction, and a grinding clearance groove 3f is formed on a corner at a base side of the flange 3a. A deep hard layer 12 deeper than the grinding clearance groove 3f is continuously formed on the entire surface layer of an area including the flange 3a and the raceway faces 3b, 3c at both sides of the flange by high-frequency quenching. Whereby a bottom part of the grinding clearance groove 3f is hardened, and the cracking from the grinding clearance groove 3f is hardly generated when it receives the axial load.

摘要： PROBLEM TO BE SOLVED: To make grooves caused by wear hard to form on the mating roll of contact in a roll for rolling mills. SOLUTION: As for the crowning parts 10, 11 which are formed at the shaft ends of the main body 2 of the roll, the length in the axial direction of the crowning parts 10, 11 of the main body 2 of the roll is made to differ in each position in the circumferential direction. In this way, the position where the boundary parts between the outer peripheral cylindrical part of the main body 2 of the roll and the crowning parts 10, 11 are brought into contact with the mating roll of contact are shifted one by one and contact stress to the mating roll of contact is dispersed in the axial direction.
