A sealing system includes a casing with an internal seat, a front edge, an opening, and a radially external lateral surface defining an annular seat. The annular seat includes an annular groove axially spaced from the front edge, itself including one or more mechanical stops, and a plurality of axial grooves connected to the annular groove and interrupting radially at least part of the front edge. The annular groove defines a bottom wall provided with projections spaced from one another and defining depressions, the projections circumferentially offset from the axial grooves. The sealing system further includes a cover with a bottom wall and an annular coupling portion. A radially inner surface of the annular coupling portion includes teeth projecting radially inward and spaced circumferentially from each other. The annular seat is configured to receive the at least one pair of teeth of the annular coupling portion of the cover.

A three-rows-of-ball bearings sliding rail is disclosed. An inner sliding rail body (1) is supported in outer sliding rail bodies (2-1, 2-2) through three rows of support ball bearings (3-1, 3-2, 3-3) which are arranged in parallel in a lengthwise direction of the inner sliding rail body. The three rows of support ball bearings (3-1, 3-2, 3-3) are respectively limited within a length range of the outer sliding rail bodies (2-1, 2-2) via ball retainers (4). Each of the outer sliding rail bodies (2-1, 2-2) includes a bottom plate (21), a first side wall (221) and a second side wall (222) which are respectively located at two sides in a widthwise direction of the bottom plate (21), are integrally formed with the bottom plate (21) and extended in a lengthwise direction of the bottom plate (21). The first side wall (221) includes a first arm and a supporting part (2211) which is bent inwardly and extends horizontally from a bottom end of the first arm. The second side wall (222) includes a second arm and an arc-shaped part (2221) which is bent inwardly from a bottom end of the second arm and integrally formed with the second arm. The three rows of support ball bearings (3-1, 3-2, 3-3) are respectively located within an upper inner corner end and a lower inner corner end of the first side wall (221), and the arc-shaped part (2221) in a cross section of the outer sliding rail bodies (2-1, 2-2); and connection lines of centers of the three rows of support ball bearings (3-1, 3-2, 3-3) form an equilateral triangle in the cross section of the outer sliding rail bodies (2-1, 2-2). This sliding rail can solve the problem of insufficient bearing capacity in the existing three-rows-of-ball bearings sliding rail, and can meet installation space requirements for a hidden sliding rail.

The disclosure provides adjustable hinge fasteners and methods thereof, for securing a bidet washing apparatus to a toilet.

A dishwasher appliance may include a slide assembly that may be mounted within the dishwasher appliance. The slide assembly may include an inner member including an engagement tab. The slide assembly may also include a ball bearing slide that is transitionable between an engaged and a disengaged position relative to the inner member. Further, the slide assembly may include an end cap that may be attached and positioned, at least partially, within the ball bearing slide.

A ball retainer for a slide apparatus and a mold for manufacturing the same. The ball retainer includes, in a width direction, a first extension part and a second extension part that are extended from a center line, forming a pre-determined angle with each other, in a length direction, a body part formed in the center, and a pair of holding parts. Each holding part is respectively formed at each end of the body part. Each holding part includes a plurality of ball insertion grooves for inserting balls that are spaced apart in the length direction. Expansion parts each having an expanding cross-sectional area are respectively formed at both sides in the length direction of the first extension part and the second extension part.

A folding knife includes a handle, a blade, and first and second bearing pivots. The handle has first and second bearing apertures that open to an exterior of the handle. The blade is disposable at least partially within the handle and between the first and second bearing apertures. The first and second bearing pivots are insertable respectively into the first and second bearing apertures. Each of the first and second bearing pivots includes a thrust bearing surface, and at least one of the first and second bearing pivots includes a radial bearing surface about which the blade is configured to rotate. At least one of the first and second bearing pivots is selectively replaceable from the exterior of the handle to convert the knife between manual and automatic functions.

An aerodynamic bearing has an inner surface defining a channel for receiving a shaft. The inner surface is deformable between a first position in which the inner surface is located at a first radial distance, and a second position in which the inner surface is located at a second radial distance. The second radial distance is greater than the first radial distance. The inner surface is formed of at least one of an elastomeric material and a plastic material.

Disclosed is a knob assembly (100) for a cooking apparatus, featuring a knob body (NB) that rotates on and moves axially along a driving shaft (71) protruding from a control panel (30). A coupling part (150), connected to the driving shaft (71), is axially movable independently of the knob body (NB). The knob body (NB) includes an exposed operating button (140) that moves independently in a direction different from the axial direction. This operating button (140) has a first position allowing axial movement without interfering with the coupling part (150), and a second position that creates interference with the coupling part (150) during axial movement. Consequently, a user must first press the operating button (140) to enable axial pressing of the coupling part (150) and driving shaft (71) for operating the cooking apparatus, thereby preventing unintended operation or errors.
