A telescoping tool includes a pole assembly, a driveshaft, a plurality of bearings, and at least one connection member. The pole assembly includes an outer pole and an inner pole. The inner pole is slidably received in the outer pole. The pole assembly is movable between a retracted configuration and an extended configuration. The driveshaft extends longitudinally in the outer pole and the inner pole. Each bearing of the plurality of bearings includes a driveshaft passage defined therein. The driveshaft passage receives the driveshaft therethrough. Each bearing further includes an end connection passage defined therein. The at least one connection member joins adjacent bearings of the plurality of bearings. The at least one connection member is disposed in the end connection passage of each of the adjacent bearings.

A mounting device includes a first mount portion and a second mount portion. The first mount portion is in communication with a first pin extending along a first axis. The second mount portion is in communication with a pair of opposing second pins extending along a second axis different than the first axis. The second pins are in rotational communication with and extend outward from the first pin. The first and second mount portions are configured to translate along the first and second axes and rotate about the first and second axes with respect to one another.

A ball screw spline assembly includes: a ball screw spline including a first nut including a first mounting surface adapted to receive a first fastening element for installing the first nut to a housing; a second nut including a second mounting surface adapted to receive a second fastening element for installing the second nut to the housing; and a shaft passing through the first nut and the second nut; the housing including a first portion and a second portion, the first portion extends in a direction substantially parallel to the shaft, and the second portion extends in a direction substantially perpendicular to the shaft; a connecting plate coupling the second nut to the first portion, the first nut is installed to the second portion; the first mounting surface and the second mounting surface are located within a space defined by the first portion, the second portion and the connecting plate, such that the ball screw spline is integrally installable to the housing. The ball screw spline is integrally installable to the housing, and thus there is no need to remove the spline nut from the shaft when installing and maintaining the ball screw spline. With the bolts adapted to be received within the housing without protruding from the housing, the robot arm including the ball screw spline assembly can be compact since the pulley no longer interferes with the bolts mounted on the spline nut.

A bushing apparatus includes: a housing with first and second ends, the housing having an outer bore passing therethrough from the first end to the second end, wherein the bore includes a reduced-diameter band located between the first and second ends; and a bushing received in the outer bore, the bushing having first and second ends and an inner bore passing therethrough from the first end to the second end of the bushing, wherein the bushing includes an outer surface having a reduced-diameter groove located between the first and second ends, wherein the band is received in the groove in a radially overlapping relationship, so as to block movement of the bushing relative to the housing.

A bearing bush includes a core, an intermediate sleeve surrounding the core in a manner extending in a circumferential direction, an outer sleeve surrounding the intermediate sleeve in a manner extending in the circumferential direction, an elastomer body disposed between the intermediate sleeve and the outer sleeve, and a stop device. In embodiments, at axial ends of the core, the stop device protrudes from the core in a radial direction and limits a movement of the intermediate sleeve in an axial direction. The intermediate sleeve is mounted on the core and, relative to the stop device, in a circumferentially rotatable manner. The outer sleeve has several projections. The intermediate sleeve has at least one counter-projection which overlaps in the radial direction with the projections for limiting the axial deflection of the outer sleeve relative to the core.
