摘要： A roller bearing for a linear motion includes a bearing body having its opposing side surfaces respectively formed with a loaded roller rolling passage and a non-loaded roller rolling passage which extend in the longitudinal direction of the bearing body. A pair of end caps are respectively secured to both longitudinal ends of the bearing body. Each of the end caps has a roller-turning passage which connects the loaded and non-loaded roller rolling passages. The roller bearing further includes a multiplicity of rollers disposed within the loaded and non-loaded roller rolling passages. The loaded roller rolling passage is constituted by two or more parallel loaded roller rolling grooves each having a depth smaller than the diameter of the rollers. The non-loaded roller rolling passage is constituted by two or more parallel non-loaded roller rolling grooves each having a depth larger than the diameter of the rollers. Further, a load bearing portion is formed on the bearing body between the adjacent non-loaded roller rolling grooves. The load bearing portion has its surface made substantially flush with the surface of the bearing body at the side at which the non-loaded roller rolling grooves are formed.

摘要： A linear slide roller bearing unit having a pair of track shafts being constituted by a block member with a substantially triangular cross-section having loaded roller rolling surfaces formed on both side surface portions of a ridge orthogonally projecting from the center of an outer inclined surface portion thereof. A movable table of substantially U-shaped cross-section being provided with a pair of bearing bodies of substantially triangular cross-section which are screwed to corresponding recesses in the movable table, each bearing body having a pair of guide ridges each having one side surface defined as a loaded roller rolling surface confronting the corresponding loaded roller rolling surface of the associated track shaft and the other side surface defined as a non-loaded roller rolling surface. Barrel-shaped or cylindrical rollers recirculate along the rolling surfaces of the bearing bodies and contact the loaded roller rolling surfaces on the track shafts. A roller retainer is attached to each of the guide ridges so as to face the corresponding inner inclined surface portion of the associated bearing body and is adapted to guide the rollers so that they can recirculate through the space defined between the roller retainer and inner inclined surface portion. The rollers in the state of serving as loaded rollers are brought into the contact with the loaded roller rolling surfaces on the track shafts at a contact angle of about 45 degrees.

摘要： An improved linear bearing unit is disclosed which has no reduction in operative performance irrespective of elimination of a conventional retainer. The bearing case of the linear bearing unit contains a plurality of non-loading ball holes and semi-circular deep track grooves whereby an increased contact surface is achieved between the loading balls and track grooves. The upper track grooves involve a right angle therebetween relative to the center of the bearing unit, causing no edge load (referred to as critical load at edge portion) to occur. Further, prestress (or preload) may be applied to loading balls in some of four track grooves.According to another aspect of the invention an outer sleeve is fitted into the bearing case, which contains four track grooves on the inner wall thereof. Side covers (or return plates) firmly secured to both end faces of the bearing case contain annular grooves corresponding to annular projections on both the end faces of the outer sleeve, U-shaped concave portions in alignment with four track grooves thereon which serve for reversing the movement of the loading balls and tongue portions at the innermost end of the side covers.
