摘要： A linear motion guide unit includes a rail having a raceway groove extending on each longitudinal side surface, and a slider fitting over the rail and movable relative to the rail. The rail includes a first rail member and a second rail member connected to each other in a longitudinal direction at a connecting portion. The first rail member has, at least at one end, a protrusion extending in the longitudinal direction. The second rail member has, at least at one end, a notch to be combined with the protrusion. In the connecting portion, the protrusion of the first rail member is combined with the notch of the second rail member to connect the first rail member and the second rail member. The protrusion and the notch are fixed with a columnar member extending in a direction intersecting the longitudinal direction.

摘要： A linear motion guide bearing 1 includes a rail 10, a slider 20, and a plurality of rolling elements. The slider 20 has formed therein a pair of circulation passages, which are spaces connecting one end and another end in each of a pair of load-carrying races, which are spaces between a pair of first rolling surfaces 41 and a pair of second rolling surfaces 42. In a cross section perpendicular to the longitudinal direction, the rail 10 includes a bottom wall portion 11, a first side wall portion 12, a second side wall portion 13, and a top wall portion 14. One first rolling surface 41 is made up of a wall surface 15A on an inner side of a first corner portion 15, which is a region where the second side wall portion 13 and the bottom wall portion 11 are connected. The other first rolling surface 41 is made up of a wall surface 16A on an inner side of a second corner portion 16, which is a region where the first side wall portion 12 and the top wall portion 14 are connected.

The slider has a lubricating oil supply device provided at least at one end face thereof. The lubricating oil supply device includes a lubricating member that retains lubricating oil and abuts against a raceway surface of the rail to supply the lubricating oil to the rail, a housing having front, rear, and bottom surfaces covering front, rear, and bottom surfaces of the lubricating member, with an upper surface of the housing being left open, and a cover that covers at least an upper surface of the lubricating member. The housing is fixed to the slider with a first fixing member. The cover is fixed to the housing with a second fixing member, without being fixed with the first fixing member.

摘要： A swing bearing allows a reduction in thickness, weight, and manufacturing cost by fixing together a pair of split rings each formed of a plate member to form an outer ring, and fixing together a pair of split rings each formed of a plate member to form an inner ring. The outer ring is composed of a pair of split rings which are obtained by splitting the outer ring at an axially midpoint of the first raceway groove, are formed of respective plate members, and are fixed together. The inner ring is composed of a pair of split rings which are obtained by splitting the inner ring at an axially midpoint of the second raceway groove, are formed of respective plate members, and are fixed together.

摘要： In a finite linear motion guide unit, a retainer for retaining rollers rolling between guide members is formed into a V-like shape to thereby increase a rated load. A first guide member is formed into a V-like concave form, and a second guide member is formed into a V-like convex form. Needle rollers are retained by the V-shaped retainer and roll on a raceway formed by facing surfaces of the guide members. The V-shaped retainer includes a pair of roller retainer plate portions for retaining the needle rollers, and a retainer connection portion. A retainer straying prevention mechanism is composed of a pinion disposed in a cross-opening, and racks disposed on the guide members and meshing with the pinion.

摘要： A curvilinear rolling guide unit allows a slider to readily straddle an endless guide rail and can prevent leakage of lubricant from a lubrication hole formed in each end cap. Each end cap is composed of an end cap body and a spacer. The end cap body has a lubrication hole, a lubrication groove, a slit which are formed in an upper portion thereof. The lubrication groove establish communication between the lubrication hole and turnaround passages. The slit extends from the lubrication hole to the under surface of the upper portion. A lubrication plug is fitted into the lubrication hole of the end cap body, closes the slit, and has a hole formed therein and serving as a lubrication passage communicating with the lubrication groove.

摘要： End rings fit over the opposite ends of the retainer inserted in the outer sleeve to keep properly the retainer against either of rotational and axial directions. End rings fit over the opposite ends of the retainer extending out of the outer sleeve to make abutment against the outer sleeve to cover the outside peripheries of the retainer. The circular groove of the retainer is composed of the raceway groove having the raceway surface with the slit, the return passage lying in parallel with the raceway groove and a pair of turnaround passages to intercommunicate between the raceway groove and the return passage. The end rings are kept in angular location against rotation by means of engagement between the first projections at the opposite ends of outer circular groove of the retainer and the second projections in the inside circular grooves of the end rings. The outer sleeve is to keep the retainer in lengthwise direction.

摘要： A porous compact impregnated with lubricant fits into a lengthwise hole in the carriage to apply the lubricant around balls rolling through a return passage to realize maintenance-free lubrication. The carriage has a flat upper portion which has threaded holes lying midway between the widthwise opposed bulges to fasten counterparts to the carriage. The carriage has widthwise opposed corners where the flat upper portion merges the respective bulges. The corners each have therein a lengthwise hole in which the cylindrical porous compact impregnated with lubricant is inserted to extend across the overall length of corners. The bulges of the carriage have threaded holes which are used to fasten the end caps to the fore and aft ends of the carriage.

摘要： A covering is easily mounted and/or demounted to envelop an overall sliding device with onboard moving-magnet linear motor. The covering helps improved propulsion, high velocity and response of a table even with small in dimension, compact in construction. End blocks are installed in opposite ends of a bed and a linear motor is placed between the bed and the table. The end blocks are made in solid bodies which are tightened to the bed together with a coil board. The end blocks have butting surfaces which can come into abutment against the ends of the table to protect the table from getting out of the bed. The end blocks have locking recesses which mate with locking jaws on the covering to fasten the covering to the end blocks.
