A bearing provides a first ring and a second ring capable of rotating concentrically relative to one another, and at least one seal provided with at least one sealing lip. The bearing further includes a sealing module providing a carrier reversibly secured to the first ring, the seal being mounted radially into contact with the carrier, a friction ring reversibly secured to the second ring, the sealing lip of the seal coming into contact with the friction ring, and at least one spacing element axially interposed between the friction ring and the second ring.

It is an object of the present invention to provide a thrust ball bearing which has a large load capacity, can realize thinned wall, and can further withstand a radial load. A pair of raceways (21, 22) include double rows of raceway grooves (23A, 23B) provided along a radial direction on surfaces facing each other. The retainer (40) includes claw-shaped protrusions (42) that protrude from peripheral edges of openings of pockets (41) in a convex manner and are arranged to face each other only in a circumferential direction of the retainer. A maximum width W of the claw-shaped protrusions (42) in the radial direction is smaller than a maximum width L of the raceway grooves (23) in the radial direction.

A bearing includes a first housing part and a second housing part. A housing gap is formed between the first housing part and the second housing part, and a bearing unit is arranged in the housing gap. In embodiments, a sealing system is provided that seals the housing gap. The sealing system may include at least one first sealing lip that is designed such that it can pivot. In embodiments, a first sealing lip is at a distance from the first housing part and/or the second housing part in the non-sealing state, and for sealing the housing gap, the first sealing lip may pivot and come into contact with the first housing part and/or the second housing part.

A slew bearing that includes an inner ring. The slew bearing also includes a first outer ring positioned about a first portion of the inner ring. The slew bearing also includes a second outer ring operably engaged with the first outer ring, wherein the second outer ring is positioned about a second portion of the inner ring opposite to the first outer ring. The slew bearing also includes at least one set of ball operably engaged with the inner ring and one or both of the first outer ring and the second outer ring. The inner ring of the slew bearing is configured to rotate about the first outer ring and the second outer ring.

The present disclosure relates to a frictional wave reducer mainly used for industrial robot joints and having an operating principle modified from that of a conventional strain wave gearing, which includes a wave generator having a conic pressurizing face on the outermost side, a toothless flex spline having a conic friction tube in which the wave generator is accommodated with the conic pressurizing face inscribed in the conic friction tube, and a toothless circular spline accommodating the toothless flex spline and having an internal conic friction face in which the conic friction tube is inscribed at a plurality of axially symmetrical points to form an internal friction wheel with the toothless flex spline. Accordingly, disadvantages of the conventional strain wave gearing are overcome to provide a reducer having high productivity and high rotation accuracy without generation of vibration and noise.

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.
