摘要： A roller bearing for linear movement of the type wherein the rollers circulate endlessly is provided. A direction changing path is provided in the shape of a circular curve reversing relative to the direction of movement of the bearing, a connecting load track and return hole at each end, for circulating the rollers. The shape of such direction changing path is obtained in such a manner that the projection of the path onto a plane perpendicular to the direction of movement of the bearing is also a circular curve. As a result, width and height of the bearing unit are made optimum so as to achieve an overall most compact bearing unit. Also a preload device and grease are arranged. The compact endless linear movement roller bearing thus obtained is made without any decrease in the bearing load capacity of prior art apparatus the same size. The roller bearing has good rigidity due to the preload device and has very small frictional resistance due to the spatially circularly curved shape of the direction changing path for the rollers.

摘要： There is provided a thin finite linear motion rolling guide unit having an apparatus for preventing a positional deviation of a holder. The guide unit comprises a U-shaped bed member, an inverse U-shaped table member, and a M-shaped holder sandwiched between the bed member and the table member. Holding holes are formed horizontally in a line at regular intervals in a pair of outside opposite walls so as to rotatably hold the balls between the opposite track grooves formed on the bed member and the table member. Circular holes are formed in the central portions in the lognitudinal direction of the inside opposite walls of the holder. A pin is pressure inserted and fixed into the holes. A single type inside belt and a double-single type outside belt are wrapped to the central portion of the pin by a half rotation in the opposite directions so that the outside belt comes into contact with outer edges of the inside belt. Both belts are extended horizontally in the opposite directions along the upper and lower surfaces of flat plate-shaped coupling portions. Upper and lower sides of both belts are coupled and fixed to coupling portions on the tables and bed sides, repectively. Thus, the motion of the holder can be restricted to 1/2 of the rolling guide unit. In place of the belts, wire ropes can be also wrapped around a pulley with double V-shaped guide grooves attached to a rotary shaft.

摘要： A linear motion rolling contact bearing assembly includes a rail having a U-shaped transverse cross section and a pair of guide grooves defined on the opposite side walls of the rail and a slider which is received in the U-shaped rail to travel along the rail. The slider is preferably provided with a pair of endless circulation paths located side-by-side each of which is provided with a plurality of rolling members. A part of each of the endless circulation paths is defined as a load path section which is located opposite to the corresponding one of the pair of guide grooves and where the plurality of rolling members are partly exposed to come into engagement with the pair of guide grooves of the rail to provide a rolling contact between the slider and the rail. The slider is also provided with a feed-in port for each of the pair of endless circulation paths, and thus the rolling members may be fed into the endless circulation paths through the feed-in ports. The feed-in port is pluggable by a plugging member and thus the rolling member are prevented from escaping from the endless circulation path undesirably.
