A simplified installation tool for installing a cover strip in a linear guide rail assembly is provided. The installation tool includes a body having a channel that extends across a bottom surface of the body that is adapted to receive a guide rail. The channel is defined by an upper surface with a lead-in angled projection and sides defined by two L-shaped guide portions that extend from the upper surface and that face each other. Two undercut areas of the channel are located between the L-shaped guide portions and the upper surface of the channel. Retention tabs of the installation tool can attach to the carriage of the linear guide rail assembly. The lead-in angled projection provides a downward force on the cover strip as the carriage travels along the guide rail to press the cover strip into a flattened state within a slot of the guide rail.

A bearing device includes a bearing member provided with a circumferentially extending sliding surface and a housing holding the bearing member on an inner circumferential surface thereof. The bearing member is provided with a bearing outer peripheral surface on one side thereof facing the housing. The bearing outer peripheral surface is surface roughened. The housing is provided with a housing inner peripheral surface on one side thereof facing the bearing member. The housing inner peripheral surface is surface roughened. When a mean height Rc of a roughness curve element of either of the bearing outer peripheral surface and the housing inner peripheral surface is X m, the remaining other of the bearing outer peripheral surface and the housing inner peripheral surface has a material ratio Rmr (X m) of roughness curve being equal to or less than 10% in at least one measurement direction.

Various embodiments of stand-off devices and methods are disclosed. The stand-off device can space a bearing assembly apart from a support, such as a frame of a conveyor belt, thereby providing access between the bearing assembly and the frame, such as for cleaning fluid. Certain embodiments of the stand-off device include a first end and a second end, with the first end being receivable in a securing hole of the bearing assembly and the second end configured to protrude from the bearing assembly.
