Abstract: A linear motion guide device includes a slider slidably attached onto a guide rail, two end caps attached to two ends of the slider and each having a channel formed between two legs, two sealing members attached to the legs and located at two opposite side portions of the guide rail and each having a wiping member for engaging with the guide rail, and two further sealing members changeably attached to the legs and located farther away from the guide rail than the previous sealing members for making different sealing structures pr conditions with the guide rail, the end caps each include two anchoring slots formed in each leg for attaching the sealing members.

Abstract: A ball circulation system for linear guide way includes a slide rail, a slider coupled with the slide rail, and two end covers of the slider with an oil scraper. A cross-wise circulation passage and a separated circulation passage respectively formed at two side of the end cover are integrally combined in one structure so as to form two independent and opposite ball circulations. By so space in the circulation system is able to accommodate more rolling balls by twice filling procedure thereby improving the efficiency of assembly work. Besides, up and down motion of the rolling balls during circulation causes a uniform lubrication effect. Allowing accommodation of more rolling balls means substantially improving load carrying ability of the linear guide way.

Abstract: An adjusting structure for adjusting amount of lubricant applied to a linear guideway comprises a self-lubricating oil tank, a positioning board and at least one adjusting board. The self-lubricating oil tank is fixed on the slide block, and the self-lubricating oil tank has an oil-storage space and a lubricating unit. The adjusting board and the positioning board are superposed and arranged between the oil-storage space and the lubricating unit. The displacement of the adjusting board can change the size of the aligned apertures of the positioning board and the adjusting board, and can precisely adjust the amount of lubricating oil transmitted from the oil-storage space to the lubricating unit. Therefore, the present invention can use the adjusting board to change the lubricating effect at any time, it not only can save lubricating oil but also can improve the lubricating effect.

Abstract: An adjusting structure for an oil feeding device of a linear guideway comprises: an oil scraping piece, an end cap, a cover plate and an oil nozzle seat. The oil nozzle seat is provided for positioning an oil nozzle, and the oil nozzle seat is fixed on the end cap. The second positioning portion of the oil nozzle cooperates with the first positioning portion of the end cap to enable the oil nozzle seat to be movable or rotatable or positioned relative to the end cap, allowing the user to adjust the feeding angle of the oil nozzle.

Abstract: A linear sliding rail has a self-lubricating unit capable of adjusting a lubricant amount supplied therefrom. The linear sliding rail has a sliding body and a lubricant tank fitted thereon. Within the lubricant tank, a lubricant-containing device is received, through which a lubricant is released to lubricant the sliding rail. Within the lubricant tank, there are also pressing bodies. Screws are used to assemble the components in the self-lubricating unit and penetrate and protrude the tank cover so that a distal end of each of the screws may be connected with an adjustment bolt. Thus, the purpose of lubricant amount adjustment may be achieved by placing the pressing bodies against the lubricant-containing device at different levels according to the user's requirement.

Abstract: A linear motion guide device includes a slider slidably attached onto a guide rail, two end caps attached to the slider and each having a chamber formed in such as a frame, and two shanks each having an end segment for engaging into the chambers of the end caps from a notch of the frame, the shanks are engaged with a ball bearing device for retaining the ball bearing device in the slider. An anchoring device may anchor the end segments of the shanks to the end caps and may detachably secure the shanks to the end caps for allowing the shanks to be easily and readily attached to the end caps without distorting or deforming the shanks.

Abstract: An ellipsograph comprises an inner toothed horizontal ring gear serving as a support. A diametrically disposed main seat bar is mounted inside of the ring gear and rotatable about the center. A vertical shaft is mounted on the main seat with a revolving arm mounted thereon. A drawing implement such as a pen is slidably mounted on said arm. The main seat bar has a small gear provided on one end of the seat bar to be driven through meshing engagement with the inner teeth of the ring gear. Such movement is transmitted through a series of sprocket and chain trains disposed on the seat bar to the vertical shaft having the revolving arm. The track of the writing implement forms an ellipse when the seat bar is caused to rotate one revolution upon the ring gear.
