ABSTRACT:
A track roller device comprising a shaft having a pair of axially spaced inside cylinders rotatably supported thereon, which cylinders have radially projecting annular flanges at the axially outer ends thereof. An intermediate cylinder is mounted on and surrounds the inside cylinders and is fixedly connected thereto. The intermediate cylinder has a radially outwardly projecting annular boss disposed substantially midway between the axial ends thereof. Separate rollers are removably mounted on the right and left ends of the intermediate cylinder and abut the opposite sides of the boss. The radial flanges of the inside cylinders are accommodated within cylindrical recesses formed in the radially outer ends of the rollers, and these flanges abut end walls formed on the rollers, whereby the rollers are thus axially confined between the flanges and the annular boss. A lubricant supply inlet extends radially through the boss for permitting lubricant to be supplied to suitable passages formed between the intermediate cylinder and the inside cylinders.
