摘要： A roller retainer 11 encloses an outer periphery of the roller 9 situated on a diagonal 20 when the roller 9 is viewed from the side surface thereof. Whether the rollers 9 are arranged in a parallel manner or in a cross manner, the roller retainer 11 is able to keep a constant position and thus the disposition of the roller retainer 11 is free from the influence of the direction the roller 9. Also, since the roller retainer 11 restricts a corner portion 9a of the roller 9, the roller 9 is difficult to slip off the roller retainer 11 and thus the roller 9 can be restricted positively, thereby being able to control the skew of the roller 9.

摘要翻译： 当从其侧表面观察辊9时，辊保持器11包围位于对角线20上的辊9的外周。 无论辊9是平行布置还是以交叉方式布置，辊保持器11能够保持恒定的位置，因此辊保持器11的布置没有辊9的方向的影响。另外， 由于辊保持器11限制辊9的角部9a，所以辊9难以从辊保持器11脱落，因此可以积极地限制辊9，从而能够控制辊9的偏斜。

A combination of linear and curve guide portions 16a and 16b different in inclination angle and a combination of linear and curve guide portion 17a and 17b different in inclination angle are formed respectively in opposite end surfaces of the roller retainer 15 in a retainer moving direction. In a linear race, the linear guide portions 16a and 17a come into contact with adjacent roller retainers 15 respectively. In a curved race, the curve guide portions 16b and 17b come into contact with adjacent roller retainers 15 respectively.

摘要： The linear motion rolling guide unit has a top seal secured to the casing which comprises a pair of lip seals that are in sliding contact with side areas of the upper surface of the track rail. The lip seals each have a pair of lip portions that incline from a base portion outwardly toward the sides of the casing. Because the lip portions are spaced a predetermined distance from each other, their sealing actions are not affected by each other, effectively preventing further ingress into the raceway grooves of foreign matters that have entered into the slider. When the pressure in the raceway grooves is increased by the supplied grease, the lip portion on the outer side is pressed with an increased force against the upper surface of the track rail, effectively preventing leakage of the grease.

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.
