The present invention relates to a linkage unit (101) for a roller chain link assembly of a caterpillar track, the unit comprising a bushing (102) which has a body and a seat (103) retaining a sealing member (104) at each of the respective axial ends of the body, an outer roller (105) mounted on the bushing (102) for rotation relative to the bushing (102) and means for reducing friction (106) disposed between the internal surface of the outer roller (105) and the outer surface of the bushing (102). The present invention also relates to a roller chain link assembly (110) having the aforementioned linkage unit (101) and a caterpillar track (301) suitable for use in track-type machines employing the roller chain link assembly (110).

Disclosed is a needle roller bearing, in particular for use in supporting a bottom roller in a spinning machine. The needle roller bearing includes an inner ring and an outer ring which are arranged such that the inner ring and the outer ring are rotatable relatively to each other around a bearing rotation axis. A rolling chamber is defined between the inner ring and the outer ring, in which a plurality of needle rollers are arranged. A solid lubricant is disposed in the rolling chamber of the needle roller bearing.

An actuator is provided and includes first and second shafts, a friction plate affixed to the second shaft, a one-way clutch that includes an inner diameter portion affixed to the first shaft, an outer diameter portion and a one-way clutch portion interposed between the inner and output diameter portions and a bearing. The bearing is disposed such that a compressive load path is formed from the first shaft, through the bearing and the outer diameter portion and to the friction plate and the second shaft. The one-way clutch portion is configured for free-wheeling during forward rotation of the first shaft that permits forward rotation transmission to the second shaft and for jamming during reverse rotation of the first shaft to create a drag event on the friction plate that inhibits reverse rotation transmission to the second shaft.

An axial rolling bearing consisting of at least one annular bearing disc which has a circumferential raceway arched in profile cross section, and consisting of a multiplicity of rolling elements formed as bearing needles or bearing rollers and arranged next to one another in a circular form, which roll on the raceway of the bearing disc and are kept at uniform distances from one another by a bearing cage. The arched raceway is formed having at least one circumferential groove-shaped depression at least in the region of one of the two ends of the rolling elements.
