A thrust bearing cage includes a piloting feature to radially locate a thrust bearing with respect to one of the shafts. Specifically, the bearing cage includes an axial extension at an outer diameter that extends beyond the rollers and around an outer diameter of end of the shaft. This feature permits elimination of a washer.

A caster 1 includes a wheel 10, a fork 20, a second member 20, and a rolling bearing 40. The rolling bearing includes an outer ring 40A, an inner ring 40B, and a plurality of rolling elements. The outer ring 40A includes a first outer ring 41 and a second outer ring 42. The inner ring 40B includes a first inner ring 43 and a second inner ring 44.

A brake assembly including an operating shaft, a yoke, and a rotating element. The rotating element bearing may be positioned between a convex bearing surface of the operating shaft and a concave bearing surface of the yoke such that the rotating element bearing may be configured to move relative to the operating shaft and relative to the yoke during actuation of the brake.

An electric actuator 1 includes: an electric motor 10; a first motion conversion mechanism 20 that has a screw shaft 21 rotatably driven by the electric motor 10 and a nut 22 screwed with the screw shaft 21, and converts a rotary motion of the screw shaft 21 into a linear motion of the nut 22; and a housing 40 accommodating the electric motor 10 and the motion conversion mechanism 20. The housing 40 includes a pair of housing split bodies 41 and 42 split by a plane parallel to an axial direction of the screw shaft 21.

The present invention relates to a rotatable stand for an LCD monitor and the purpose thereof is to apply a rotating body having a specific structure to the LCD monitor, which is installed on a table therethrough, so as to enable the LCD monitor to freely and continuously make a full 360-degree rotation in left and right directions, while the conventional fixed structure of the LCD monitor is being maintained.

Provided is an electric actuator (1), including: a motor part (A); and a motion conversion mechanism part (B). The motion conversion mechanism part (B) includes: a ball screw shaft (33); and a ball screw nut (32), which is rotatably fitted to an outer periphery of the ball screw shaft (33), and is provided so as to be capable of transmitting torque with a rotor (24) of the motor part (A) rotatably supported through intermediation of a rolling bearing (27, 30). The ball screw shaft (33) advances toward one side in the axial direction or retreats toward another side in the axial direction in accordance with a rotation direction of the ball screw nut (32). In the electric actuator (1), a needle roller bearing (47) serving as a thrust bearing is arranged adjacent to the ball screw nut (32) on the another side in the axial direction.

A vehicle weight measurement device includes a diaphragm which covers an opening area of a groove portion of a mounting part to form an oil chamber of a predetermined space together with the groove portion; a pressure sensor which detects a change in pressure of measurement fluid in the oil chamber; a first piston which presses the diaphragm; a second piston which presses the first piston; and a bearing unit interposed between the second piston and a spring bush which receives one end of a spring of a suspension device and is relatively rotatable. The bearing unit includes a thrust needle bearing which swingably supports a load in a longitudinal direction of the suspension device, and a slide bush which does not receive a load in the longitudinal direction and receives a load in a radial direction while causing constant damping to swinging.

An object is to provide a mounting structure of a bearing member which enables size and weight reduction of entire apparatus and also contributes to cost reduction thereof. The mounting structure of a bearing member includes: a bearing member for supporting a rotary shaft; a case member to which the bearing member is mounted; and a mounting plate for clamping the bearing member in an axial direction of the rotary shaft in conjunction with the case member, wherein the mounting plate includes a mounting portion of a counter member which is mounted to the case member and clamps the case member in the axial direction in conjunction with the counter member.
