Abstract: A tappet roller assembly in which a roller shoe has a roller bore shaped to receive and retain a roller. The roller is sized and configured to rotate within the roller bore. The roller shoe may have a lubricating passage extending from a peripheral surface of the roller shoe to the roller bore to lubricate the roller.

Abstract: An apparatus and method of producing a pump including a housing and a cam received within the housing that is rotatable relative to the housing. The cam includes an axis of rotation. The pump further includes a retainer plate operable to abut the cam to restrict movement of the cam in a first direction along the axis of rotation. The pump further includes a biaser, such as a spring, operable to place a first constant force in the first direction on the retainer plate.

Abstract: A roller assembly, comprising a roller shoe having a bottom surface, and a groove at the bottom surface, the groove having a semicircular portion and a straight portion extending from the semicircular portion, the semicircular portion having a first diameter and the straight portion having a first width, and a cylindrical roller positioned in the roller shoe groove, the cylindrical roller having a second diameter, wherein the first width is greater than or equal to the first diameter and the second diameter is less than the first width.

Abstract: A rolling member guiding structure installed in the circulation tunnel of a sliding block in a linear transmission mechanism. The guiding structure has a bar shaped part disposed along the inner wall of the circulation tunnel of the sliding block so as to form the inner cavity of the circulation tunnel into a predetermined guiding space thereby guiding the rolling members to circulate along the circulation tunnel heading to a predetermined direction. With this structure, the contact area between the rolling member and the circulation tunnel can be minimized so as to reduce the frictional resistance to the rolling member and smooth the operation of the linear transmission mechanism.

Abstract: A linear motion guide apparatus includes a housing having a chamber formed by two side walls for slidably receiving an elongated track rail, one or more endless ball rolling passages are formed in the housing for receiving a number of bearing members, one or more ball retaining devices each include an elongated rod for engaging with the bearing members and for retaining the bearing members to the housing, and a fastening device for fastening the ball retaining device to the housing and to prevent the ball retaining device and the bearing members from being disengaged from the housing. A fastener may be used for fastening each of the end portions of the ball retaining device to the housing.

Abstract: The present invention relates to a retaining device for rolling-element and its manufacturing method, which is made up of the partition and the link-ring. The characteristic of the retaining device for rolling-element is that the partition is a hollow-ring-like structure to separate the rolling-elements, and the link-ring joins the partitions to become an unitary structure. Besides, the characteristic of the manufacturing method of the retaining device is use a bat to pass through the shaping mold, therefore reducing the degree of difficulty of manufacture, and saving the cost of manufacture.

Abstract: The present invention relates to a circulating apparatus for a linear guideway, and more particularly to the component of the unloading circulating portion of a rolling module of linear motion, the circulating apparatus is J-shaped, an end of which is disposed in the through holes, and end of which is connected to the loading path of the sliding block, the circulating apparatus is provided with a circulating path for enabling the rolling elements to move endlessly and circularly, in the circulating path are arranged two opposite grooves, the circulating apparatus comprises an outer circulating half tube and an inner circulating half tube which are connected together along the two opposite grooves.

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.
