In a self-aligning bearing positioning and supporting one end of a rotation shaft in an axial direction and allowing the rotation shaft to bend, the bearing is structured as a double row cylindrical roller bearing with aligning ring, a first row of cylindrical roller group is positioned by being held in an axial direction between a radially inward flange provided in an intermediate portion in an axial direction of an outer ring having an outer peripheral surface formed in a spherical surface shape, and a flange provided in one outer end of two inner rings, and a second row of cylindrical roller group is positioned by being held in the axial direction between the flange of the outer ring and a flange provided in another outer ends of the two inner rings.

Self-aligning bearing

In a torque releasing device, a bearing is composed of an angular contact ball bearing, raceway surfaces of which are applied with a pre-load in order that the occurrence of fretting at the bearing during torque transmission may be prevented. Thus is ensured that the torque is securely released.

Torque releasing device

A roll apparatus provided at a continuous caster for transferring a cast piece to a predetermined location includes: at least three divided rolls arranged to align concentrically and in an axial direction thereof to constitute a roll forming a cast piece transfer path. At least one end portion of at least of the divided rolls is supported by a cylindrical roller bearing of a full roller type.
