Abstract: An anti-dust structure for a sliding block of a linear guideway comprises a sliding block, two end caps, plural rolling elements, a flexible anti-dust strip and a rail. The two end caps are assembled to both ends of the sliding block, the rolling elements are disposed on the rail. Between the end cap and the sliding block is defined a circulating path. The two end caps are each extended from an inner side thereof to form a linking portion, and the two linking portions of the two end caps are linked to each other to define an endless positioning groove including two longitudinal grooves and two transverse grooves. The flexible anti-dust strip is disposed in the positioning groove of the end caps and integrally formed with protruding lip portions for cooperating with the two longitudinal grooves.

Abstract: A rolling element chain system for a linear guideway comprises a slide rail, a slide block, a plurality of rolling elements and a rolling element chain. The circulating path of the slide block is interiorly provided with a guiding groove with a width C, and the rolling elements roll within the circulating path and are confined by the rolling element chain. The rolling element chain has a plurality of spacers for separating the rolling elements from one another and linking portions with a thickness t for linking the rolling elements with one another. The spacer at each end of the rolling element chain has a retaining capacity B for holding the corresponding rolling element. The above structure satisfies the relation: C<t+B/?.

Abstract: A linear guideway essentially comprises plural bolt-hole covers, and each of the bolt-hole covers essentially includes a main body and an elastic part. The main boy includes a cover plate and a positioning portion. The periphery of the positioning portion is provided with a guiding portion and a groove, and the positioning portion is provided with plural cutting grooves vertical to the cover plate for offering flexibility to the positioning portion. The elastic part is installed in the groove of the positioning portion. With the elastic functions of the positioning portion and the elastic part, the bolt-hole cover can be fixed in the bolt hole more stably through the interference with the bolt hole.

Abstract: A linear motion guide device includes a slider slidably attached onto a guide rail and each having one or more longitudinal grooves for forming a ball guiding channel between the slider and the guide rail, and two end caps attached to the ends of the slider, the slider includes two end portions each having two notches communicating with the longitudinal grooves, and two plates are disposed between the slider and the end caps and each include two or more ears engaged into the notches of the slider for anchoring the plates to the slider and each ear having an inclined surface for reducing the noises that may be generated by the movement of the ball bearing device.

Abstract: A synchronous spacer with a guiding block comprises strip-shaped links, a plurality of spacer elements, and a guiding block fixed at the end of the links. An arch-shaped surface is formed on the guiding block and is located correspondingly to inner surface of the track of the linear guideway, the guiding block is larger than spacer element of the synchronous spacer but is smaller than the rolling elements. With the guidance of the guiding block, the synchronous spacer is prevented from impacting the inner surface of the track, enabling the linear guideway to move smoothly and stably.

Abstract: A guiding device for a synchronous connector comprises a strip-like synchronous connector and at least one connecting member. Both ends of the synchronous connector are formed with two opposite fixing seats. The connecting member with elastic deformation characteristic is serially connected and fixed in the fixing seats at both ends of the synchronous connector, slide correspondingly to the clearance change during the operation of the two ends of the synchronous connector, and bend correspondingly to the turning action of the synchronous connector. By such arrangements, the elastic deformation characteristic of the connecting member can be utilized to avoid the collision interference with the rail wall surface, and the linear guiding device will be circulated smoothly and stably. In addition, the guiding device has the effect of absorbing the radial deformation of the synchronous connector and producing sufficient degree of freedom.

Abstract: A Synch-Motion spacer comprises a plurality of spacer elements, and strip-shaped links. An abutting surface is formed on each of the spacer elements and is located on the outer periphery of the receiving space and is arranged in the rolling direction of the rolling elements. An interval L being 0.3% larger than the abutting portion is formed in the abutting portion and is located in the rolling direction of the rolling elements. The abutting portion is made of thermoplastic polyamide elastomer with an elongation of 0-0.3%. The elongation of the spacer after oil immersion is less than the interval between the rolling elements and the spacers, so that no interference will be caused between the rolling elements.

Abstract: A synchronous spacer with a guiding block comprises strip-shaped links, a plurality of spacer elements, and a guiding block fixed at the end of the links. An arch-shaped surface is formed on the guiding block and is located correspondingly to inner surface of the track of the linear guideway, the guiding block is larger than spacer element of the synchronous spacer but is smaller than the rolling elements. With the guidance of the guiding block, the synchronous spacer is prevented from impacting the inner surface of the track, enabling the linear guideway to move smoothly and stably.

Abstract: An anti-dust structure for a sliding block of a linear guideway comprises a sliding block and a flexible anti-dust strip. A positioning groove is formed in the inner surface of the sliding block and located correspondingly to the upper steel ball groove. The flexible anti-dust strip has a plurality of lip portions that protrude out of the positioning groove, and the lip portions come into contact with the top surface of the rail. In this way, the flexible anti-dust strip can scrape off the grease and dust accumulated on the top surface of the rail at all times, preventing the dust and grease entering the upper steel ball groove via the top surface of the rail, and thus obtaining a better anti-dust function and ensuring the service life of the linear guideway.

Abstract: A lubrication device for linear slide guide, comprising of an end cover made up of resin and a cover plate made up of polymer elastomer wherein the cover plate is closely installed in the placement space of the end cover, meanwhile, the buffer part of the cover plate can be placed in the upward U-turning part and the downward U-turning part on two sides of the end cover to form a complete sealed body, therefore, the flowing channel of the end cover and the flowing space of the cover plate can form a continuous flowing channel so that when lubricant enters the side lubricant hole, the flowing space can evenly distribute the lubricant and let the lubricant enter the lubricant hole through lubricant channel to lubricate rolling component and sliding rail.
