摘要： A motion guide apparatus is provided which can prevent a ball from contacting an edge of a ball rolling groove of a track member when the ball transfers from a rolling surface of the inner peripheral side of a turn-around path (an inner peripheral-side component) to the track member. The motion guide apparatus includes: a track member (2) including a ball rolling groove (2a); and a moving member assembled to the track member (2) in such a manner as to be movable relative to the track member (2). The moving member includes: a moving member body having a loaded ball rolling groove facing the ball rolling groove (2a), and a return path substantially parallel to the loaded ball rolling groove; and a lid member having a turn-around path. In cross section of the motion guide apparatus perpendicular to a length direction of the track member (2), letting the radius of curvature of the ball rolling groove (2a) be R, and letting the distance from a ball center (O) to a rolling surface (21) of the inner peripheral side of the turn-around path (an inner peripheral-side component (9a)) be r, R>r is set.

摘要： A circumferential guide for rolling bodies for use in a linear guide unit which has a carriage-type part and a rail-type part, that has at least one loaded roller body row and one unloaded roller body row during the intended operation. The circumferential guide is configured as a pre-mountable unit. A linear guide unit is also disclosed that contains at least one circumferential guide. The circumferential guide has at least one component for the rolling bodies, which at least partially guides both the loaded rolling body rows and the unloaded rolling body rows (Ru) during the intended operation. This configuration achieves that the parts requirement for the circumferential guide can be held low, resulting both in a reduction of production costs and in a compact and stable shape of the same.

摘要： A sealing member for a rolling device is applied to a rolling device with inner and outer members and a plurality of rolling members between so the rolling members can roll to allow relative rotational or linear movement of the outer member with respect to the inner member. The sealing member includes an inner and outer lip parts that press the inner and outer members, respectively. The outer lip part is less rigid than the inner lip part. The sealing member may have a substantially circular shape and surround the inner member. Alternatively, the sealing member may have a substantially plate-like shape and extend in a direction of relative movement of the outer member with respect to the inner member. The sealing member for a rolling device configured as described above and a rolling device provided with the sealing member can be adequately used even in a hostile environment.

摘要： This ball spline is capable of omitting ball retaining claws on an outer cylinder, forming by grinding raceway grooves in an inner surface of the outer cylinder easily with a high precision, positioning and fixing retainers simply on the outer cylinder, and reducing the manufacturing cost. In this ball spline, each of the retainers is formed by a pair of ball retaining units, which are fastened to the outer cylinder by engaging outer projections formed on the ball retaining units with grooves formed in the outer cylinder. The locking bores in spacer rings are engaged with locking projections on the ball retaining units, whereby the spacer rings are fixed to the ball retaining units.

摘要： A linear motion guide unit is described that allows seal attachment to be performed highly accurately and easily as well as preventing dislocation of the seals after attachment. Said effects are obtained by providing projections and slots in a slider and seals and mutually engaging these projections and slots. In addition, a linear motion guide unit is described that allows lubricant to be supplied both quickly and easily without having to disassemble the linear motion guide unit even when small in size. Said effect is obtained by forming lubricant injection holes in the seals and injecting a lubricant such as grease through said lubricant injection holes with a lubricant injector.

摘要： An unlimited sliding ball spline therefore includes a spline bearing consisting of an outer cylinder, a ball retainer provided on the inner side of the outer cylinder, and a plurality of balls held by the ball retainer in a plurality of unlimited passages formed on the inner side of the outer cylinder, in such a manner that the balls can be rolled in the unlimited passages; and a spline shaft supported on the plural balls in the spline bearing. The ball spline is capable of making linear, axial reciprocating movements and torque-transmitting rotational movements separately or simultaneously. A circumferential support bearing is disposed coaxially around the outer cylinder and is rotatable with respect thereto and further has a pair of angular contact bearings located on an inner surface thereof. The angular contact bearings are separated by a pre-pressure regulating spacer. A plurality of balls are located circumferentially between each angular contact bearing and corresponding ball rolling grooves on the outer surface of the outer cylinder.
