A slider S is provided with a pair of guide holes 31, 32 for forming a return guide path. Guide cylinders 34 in which the rollers 37 roll are inserted in the guide holes 31, 32. A pair of passage groove 42, 43 having different depth and intersecting with each other is provided in each of the end caps e1, e2. A divider frame 36 is provided integrally with one end of each guide cylinder 34 for defining the intersecting passage grooves.

摘要： A retainer to be installed in a linear motion guide unit is disclosed which composed of embracing parts to hold a roller on diametrically opposite sides thereof, and connecting flanges joining the embracing parts together with one another. The embracing parts to hold the roller between them are each made with a first lip raised above any one side thereof, and a second lip raised above another side thereof. The first and second lips raised in opposite direction are placed in an offset or staggered relation with one another in lengthwise direction of the embracing part or in axial direction of the roller so as to be tough to suffer any distortion and/or damage on molding operation. The retainer can sustain ample lubricant near the lips. The embracing parts come into rolling-contact with the rolling surface of the roller while the connecting flanges come into sliding contact with axially opposite ends of the roller.

摘要： A linear motion guide unit is disclosed, in which a slider fitting over a guide rail for movement is comprised of three components save rolling elements. The three components are joined together in the slider with using no fastener such as threaded fasteners, but just with fit-engagement that makes it possible to shrink the slider down in size. The three components are made up of a carriage made therein with raceway grooves and return passages, an upper component applied to the carriage to fit into recesses on the top surface of the carriage, and a lower component applied to the carriage to fit into recesses on the bottom surface of the carriage. The upper and lower components are joined together with the help of fit-engagement of hooks and hook holes, with holding firmly the carriage between them.

摘要： An expansion-molded article of a polypropylene resin is produced by filling pre-foamed particles of the polypropylene resin, which have a crystalline structure featuring an inherent peak inherent to the polypropylene resin and a high-temperature peak on the temperature side higher than the temperature corresponding to the inherent peak on a DSC curve obtained by differential scanning calorimetry of the pre-foamed particles and a bulk density of 0.04 g/cm.sup.3 or higher and require melting energy of 8-12 J/g at the high-temperature peak, in a mold without applying any pretreatment to the pre-foamed particles to build up an internal pressure therein, and then heating the pre-foamed particles, whereby the pre-foamed particles are caused to expand into the expansion-molded article conforming with the mold. The pre-foamed particles may alternatively have a bulk density lower than 0.04 g/cm.sup.3 and require melting energy of at least 8 J/g.

摘要： A slider for a linear motion rolling guide unit can ensure a smooth rolling movement and a reliable lubricating capability and eliminate the need for accurate dimension control to reduce the manufacturing costs. A turning corner 9 in an end cap 2 is made up of a pair of arced paths 9c connecting with a rolling path in the casing 1, and a straight path 9d providing a connection between the arced paths 9c and extending in a direction approximately perpendicular to the rolling path. The lubricating member A mounted in the end cap 2 has a lubricating face 18a exposed to the linear path 9d, and maintains a relation of the lubricating face 18a intersecting the outer peripheral faces of the arced paths 9c. A recessed area 19 is formed between the outer peripheral face of each arced path and the lubricating face 18a in a surplus length region extending outward from the intersection between the lubricating face 18a and the outer peripheral face of the arced path 9c.

摘要： The sliding mechanism including rolling elements 3 as a main element is protected against entry of foreign substances. First, second auxiliary lips 14, 15 are formed in positions on inclined faces 9b formed on lips 9 of end seals S facing and making contact with end faces of sealing members 4, 5. Gaps 10, 11 formed between different levels of the end faces of the sealing members 4, 5 and the inclined faces 9b of the lips 9 are filled with the first, second auxiliary lips 14, 15.

摘要： A linear motion guide unit is disclosed in which a tubular composition to provide a return passage is high in mechanical stiffness and also makes certain of sustainable application of lubricant to rolling elements rolling through the return passage, thereby ensuring proper lubrication under maintenance-free operation. The tubular composition to make the return passage is composed of a tubular skeleton to guide the rollers, and a porous compact impregnated with lubricant. The tubular skeleton is made up of forward and aft ends, a lengthwise column and a flexible spine, which extend between the ends. The flexible spine includes lengthwise opposite relief portions and a flexible middle section, which fit into the porous compact with separating from the porous compact to make a clearance between them. The flexible spine deflects as the rollers roll through the return passage, permitting the rollers coming into touch with the porous compact to lubricate the rollers.

摘要： Pre-foamed particles of an uncrosslinked, linear low-density polyethylene have a crystalline structure characterized in that two endothermic peaks appear on a DSC curve obtained by differential scanning calorimetry of the pre-foamed particles (said DSC curve having been obtained by heating 1-5 mg of the pre-foamed particles to 220.degree. C. at a rate of 10.degree. C./min by a differential scanning calorimeter) and the energy at the endothermic peak on the higher-temperature side is 5 J/g or more. A process for the production of the pre-foamed particles of the uncrosslinked, linear low-density polyethylene is also disclosed.
