摘要： A sleeve fits in a through-hole in a carriage to provide a return passage which makes sure of both the flexibility and the stiffness of the sleeve. The sleeve is constituted with fore and aft circular ends, a pair of columns and a pair of flexible columns lying lengthwise between the fore and aft circular ends to guide the roller, lengthwise slits lying between the flexible columns and the columns, and complementary ends made on the terminals of the fore and aft circular ends. The flexible columns have raised lands having curved outer surfaces, and recessions flanked by the raised lands and having rolling wall surfaces or the return passage. The raised lands and the recessions are arranged alternately in the lengthwise direction of the sleeve to give the sleeve the capability of elastic deformation.

摘要： An effective contact length in race surfaces formed on grooved races cut in an outer ring and an inner ring is made as greater as permitted to improve the load-carrying capacity, and correspondingly guide parts born against axially opposite ends of a roller are made as less as possible in width to reduce frictional contact resistance applied to the axially opposite ends of the roller, thereby preventing a skew of the roller. An inside circular surface on the outer ring is staggered or different in level on opposite sides of a outside grooved race to make greater the race surface than an effective contact length of circular rolling surfaces of the rollers and correspondingly less the guide part in width than the race surface.

摘要： A linear motion guide unit includes a guide rail and a slider. A carriage of the slider has a central portion located above the guide rail, and wing portions which extend downward from widthwise opposite ends of the central portion. Shoulder portions of the carriage located in inner boundary regions between the central portion and the wing portions of the carriage have first inclined surface so that the shoulder portions have padding portions. Corner portions of the guide rail located between an upper surface and longitudinal sides of the guide rail have second inclined surfaces which face the first inclined surfaces of the carriage and extend in the longitudinal direction parallel to the first inclined surfaces. The first inclined surfaces have an inclination angle substantially the same as an inclination angle of the nose surfaces of threaded holes formed in the carriage for attachment of a counterpart member.

摘要： A porous compact impregnated with lubricant fits into an end cap in a fashion exposed in part to a turnaround passage to apply the lubricant around balls while the balls roll through the turnaround passage. The porous compact is placed in a concavity in an end cap major part and a slot rounded at opposite ends thereof is formed in an outside curved portion of the turnaround passage to communicate the concavity with the turnaround passage. An applicator nose of the porous compact is exposed to the turnaround passage through the slot. The balls while being guided along edges of the slot come into rolling-contact with the exposed surface of the porous compact to be coated with the lubricant.

摘要： End rings fit over the opposite ends of the retainer inserted in the outer sleeve to keep properly the retainer against either of rotational and axial directions. End rings fit over the opposite ends of the retainer extending out of the outer sleeve to make abutment against the outer sleeve to cover the outside peripheries of the retainer. The circular groove of the retainer is composed of the raceway groove having the raceway surface with the slit, the return passage lying in parallel with the raceway groove and a pair of turnaround passages to intercommunicate between the raceway groove and the return passage. The end rings are kept in angular location against rotation by means of engagement between the first projections at the opposite ends of outer circular groove of the retainer and the second projections in the inside circular grooves of the end rings. The outer sleeve is to keep the retainer in lengthwise direction.

摘要： A porous compact impregnated with lubricant fits into a lengthwise hole in the carriage to apply the lubricant around balls rolling through a return passage to realize maintenance-free lubrication. The carriage has a flat upper portion which has threaded holes lying midway between the widthwise opposed bulges to fasten counterparts to the carriage. The carriage has widthwise opposed corners where the flat upper portion merges the respective bulges. The corners each have therein a lengthwise hole in which the cylindrical porous compact impregnated with lubricant is inserted to extend across the overall length of corners. The bulges of the carriage have threaded holes which are used to fasten the end caps to the fore and aft ends of the carriage.

摘要： The turning bearing has a separator whose leading and trailing sides are concaved to fit over circular rolling surfaces of the rollers to provide concavities where concaved surfaces lying either in parallel with and in perpendicular to the axis of the roller. The rollers fit in the separator in either of two different directions. The separator can be easier installed into the raceway through a loading hole without the posture of the separator in mind. The separator has a quadrilateral in a transverse cross-section perpendicular to a traveling direction of the separator of which a peripheral surface is in opposition to the outer ring and the inner ring. The separator has a center through-hole. The concaved surfaces in the separator are contoured in arced or curved profiles and bulge gradually closer to a circular edge of the through-hole to form arcing bulges at bottoms of the curved surfaces.

摘要： A loading hole made in either of an outer ring and an inner ring is provided in two rows of raceways defined between the outer ring and the inner ring, one to each raceway. The loading hole is set out of the guide surface and, therefore there is no fear that a closure fitted in the loading hole causes any obstacle to the rolling movement of the rollers. The loading hole extends radially of the bearing at a location that a center line of the loading hole lies set-off or biased from a center of the roller. An opening edge of the loading hole is exposed to the raceway in a location out of the guide surface, so that the rollers are allowed to roll smoothly without touching with the innermost edge of the closure.
