In some embodiments, a roll for use in a rotary manufacturing system includes a cylindrical contact section that extends along a roll axis and may include a contact surface, an end face, a channel section, and a core section may have a core wall and a core shaft. The channel section may include a first wall and a channel shaft, and the channel section may define a channel between the first wall and the channel shaft that encircles the channel shaft and the roll axis. The channel may have an inner face, an outer face, and a channel end. The channel section and the core section may be attached to each other.

In the linear motion guide unit, a retainer plate for retaining rolling elements, or rollers, is prevented from deformation so as to smoothly guide the rollers. The retainer plate is composed of a retainer member, frame members fitted into respective through holes formed in the retainer member, and a fixing member disposed in a longitudinally extending recess of the retainer member. The frame members form a predetermined gap between the fixing member and a carriage. Tightening forces of fastening bolts are not applied to the retainer member, thereby avoiding deformation of the retainer member.

Disclosed is a rail of a machining apparatus having a traveling carriage, wherein rail members of a rail are connected at a rail member connecting portion in series such that running surfaces of adjacent rail members are in contact with each other, wherein the rack members are arranged in series on an attachment surface of the rail member such that an interval between teeth of adjacent rack members at a rack member opposing portion at which the adjacent rack members are opposed to each other is the same as a predetermined tooth pitch of the rack members, and wherein the rack members are attached to an attachment surface of the rail member by bolts which are inserted through the elongated holes formed on the attachment surface and which are screwed into the threaded holes of the rack member.

The present invention provides a composite static rotary table and a method for protecting a composite static rotary table. The composite static rotary table comprises: a housing body provided with a mounting space; a rotary table body driven by a connecting mandrel to rotate; a base, the connecting mandrel being arranged through the base; an air stopping film arranged between the rotary table body and the base; and an auxiliary supporting assembly fixedly arranged in the mounting space and configured for assisting the rotary table body to be levitated relative to the base. The present invention is intended to solve the problem of ensuring the stable non-contact rotation of the rotary body of the rotary table relative to the base, while improving the bearing capacity of the rotary table.
