In a cross section perpendicular to the longitudinal direction, the rail 10 includes a bottom wall portion 11, a first side wall portion 12, a second side wall portion 13, and a top wall portion 14. One first rolling surface 41 is made up of a wall surface 15A on an inner side of a first corner portion 15, which is a region where the second side wall portion 13 and the bottom wall portion 11 are connected. The other first rolling surface 41 is made up of a wall surface 16A on an inner side of a second corner portion 16, which is a region where the first side wall portion 12 and the top wall portion 14 are connected.

An aircraft seat module includes an enclosure unit which delimits a flight passenger seating region at least partially, and includes a door unit which at least closes a passage region to the flight passenger seating region in one or more operation states. The aircraft seat module further includes a bearing device which supports the door unit movably relative to the enclosure unit and has for this purpose a bearing module having a first bearing element and a second bearing element which are supported such that they are movable relative to each other.

An extreme load creeper interface comprising a planar roller array wherein a plurality of extreme load rollers with parallel rotational axes are dispersed both laterally and longitudinally within the plane, so as to fractionalize a weight applied perpendicular to the plane, and thereby promote longitudinal motion of the roller array in a direction perpendicular to the plurality of roller rotational axes.

In a finite linear motion guide unit, a retainer for retaining rollers rolling between guide members is formed into a V-like shape to thereby increase a rated load. A first guide member is formed into a V-like concave form, and a second guide member is formed into a V-like convex form. Needle rollers are retained by the V-shaped retainer and roll on a raceway formed by facing surfaces of the guide members. The V-shaped retainer includes a pair of roller retainer plate portions for retaining the needle rollers, and a retainer connection portion. A retainer straying prevention mechanism is composed of a pinion disposed in a cross-opening, and racks disposed on the guide members and meshing with the pinion.

A system for transporting fiber ends can comprise a fiber supply assembly that supplies fiber along a first axis. A plurality of eyeboards can be positioned along the first axis. Each eyeboard can define a plurality of openings therethrough. Each opening of the plurality of openings can be configured to receive therethrough a fiber from the fiber supply assembly. A track can extend along the first axis. The track can pass proximate to each eyeboard of the at least one eyeboard. A carriage can be movable along the track. The carriage can define at least one fiber attachment element. An actuator can be configured to move the carriage along the track.

A guide assembly includes an annular guide body defining a cavity, and a plurality of roller assemblies mounted within the guide body. Each roller assembly includes an annular roller mounted onto a pin and arranged to rotate around the pin. The pins are arranged such that their axes define a ring around the interior of the guide body and the annular rollers arranged to protrude through respective openings in the guide body into the cavity. Each annular roller has a concave outer surface.

An aircraft seat module comprises an enclosure unit which delimits a flight passenger seating region at least partially, and comprises a door unit which is at least configured to close a passage region to the flight passenger seating region in at least one operation state, and further comprises a bearing device which is configured to support the door unit movably relative to the enclosure unit and has for this purpose a bearing module comprising a first bearing element and a second bearing element which are supported such that they are movable relative to each other.

A roller carriage for displaceable linear guidance in a longitudinal direction on a rail element is disclosed. The roller carriage includes a carrier, a first roller or pair, a second roller or pair, and roller or pair. Every one of the first roller or pair, the second roller or pair, and the third roller or pair is mounted on the carrier such that each can rotate about a rotating axle. The rotating axles are substantially parallel to one another and the first roller or pair, the second roller or pair, and the third roller or pair are disposed on the roller carriage such that the first roller or pair can be brought into engagement with a first track of the rail element and the second roller or pair and the third roller or pair can be brought into engagement with a second track of the rail element. One of the first roller or pair, the second roller or pair, and the third roller or pair is mounted such that it can move in a transverse direction perpendicular to the longitudinal direction relative to the carrier, and wherein the movably mounted roller is resiliently pretensioned in transverse direction by a first spring element.

The present disclosure describes bearing assemblies for a mover of a linear motor system. The bearing assemblies may include a plurality of bearings, a housing that retains the bearings, a plurality of springs biasing at least one of the plurality of bearings towards a track of the linear motor system, and at least one dampening element dampening movement of one or more of the plurality of springs.

One or more embodiments of the present disclosure are directed to a transmission mechanism. The transmission mechanism may include a guiding rail, and a slider movably disposed on the guiding rail, wherein the slider may be provided with a rolling part, the rolling part may roll with respect to the guiding rail, and limit the slider in a first direction and a second direction of the guiding rail, and the first direction and the second direction may both be perpendicular to a length direction of the guiding rail, and an angle between the first direction and the second direction may be greater than 0° and less than 180°.
