At SC Industries, we have earned a reputation among customers in a number of industries for our ability to machine precision thin-walled components with proportionally large diameters. This carburized thin wall bearing sleeve was machined for a customer in the off-road construction and mining equipment industry.
As with any rotating component, bearings must be machined precisely to ensure proper operation of the machinery in which it is to be used. If tolerances are not met, the bearing can cause vibration, which not only leads to failure of the bearing itself, but premature wear of other mechanical components.
The bearing shown here has an outer diameter of 9.4″, an inner diameter of 8.9″, and a length of 4″. Dimensional tolerances as tight as ± 0.0004″ and a surface finish of 32 µin were achieved by utilizing the capabilities of our CNC lathe in conjunction with precision grinding equipment.
The bearings were machined in accordance with customer provided prints and heat treated using a tightly controlled process to carburize the part to the specified depth without causing distortion. For this project, we manufactured a total of 100 sleeve bearings with a turnaround time of 4 weeks.
