Caterpillar D7G dozer carrier roller assy supplier
The top rollers maintain the track link at its optimum height to ensure a tight binding of all the different elements for more efficient machine operation. A thorough study of the OEMs (Original Equipment Manufacturers) original drawing representing the upper roller required performances, will allow us to manufacture all the different types of carrier rollers available on the market. The best solution will be applied to our production line after rigorous analysis of the drawings.
Our products are made of 40Mn to 50Mn steel, which will go through a high frequency induction modulation process in order to obtain HRC50-55. This material, chosen for its quality and durability, meeting the requirements of heavier weights as well as the precision of our production lines, are the main competitiveness of our top rollers. All of the top roller shells are assembled with O-rings, bushings, seals, shaft and other small parts. Each step is strictly inspected to ensure pressure resistance and tensile resistance.
