A track joint assembly includes a first track shoe and a second track shoe, and a cartridge pin coupling together the first track shoe and the second track shoe. A sealed and lubricated track joint is formed by pin lugs on the first and the second track shoes, a cartridge pin, a pin retainer, a pin bore extending through pin lugs of the coupled-together track shoes, and a pin stop located in one of the pin lugs to inhibit displacement of the cartridge pin.

A cartridge pin assembly in a track chain assembly includes a sleeve bearing having a flared end.

A track roller includes a roller shell, a roller shaft extending through the roller shell, and a collar. The collar includes a center body interference-fitted upon the roller shaft, and a seal carrier. A clearance extends radially between a center body outer surface and a face seal assembly held in axial compression between the seal carrier and the roller shell. An oil void is formed in the center body and fluidly connected to the clearance to provide an increased oil volume for lubrication and heat-dissipation.

A track pin assembly includes a pin having a first axial end and a second axial end configured to engage a respective outer link of a joint, a first cavity which defines a tank for containing lubricating oil or grease, and a second cavity arranged at the second axial end of the pin and open at the second axial end of the pin. A sensor, arranged in the second cavity, includes a sensor element configured to measure a temperature and to generate a signal indicative of the measured temperature, and a transmitter configured to irradiate a measuring signal that is representative of the signal generated by the sensor element. A power source, arranged in the second cavity, is configured to constantly supply the sensor.

A machine system includes a roller frame and a roller assembly mounted to the roller frame. The roller assembly includes first and second clamping collars positioned upon a roller shaft and each including a lower and an upper collar section. Fasteners clamp the lower and upper collar sections to the roller shaft to form static seals. The clamping collars may be formed with splitlines to enable the clamping collars to deform so as to simulate interference fits with the roller shaft.

A rotating member attachment assembly includes a shaft including a cylindrical configuration defining a cylindrical axis, a first axial end and a second axial end along the cylindrical axis; a first coupler defining a first hole that defines a first hole axis and that is configured to receive the shaft, the first coupler further including a first inner axial end, and a first outer axial end; a first shaft bushing disposed on the shaft at the first axial end; and a first coupler bushing disposed in the first hole of the first coupler.
