Roller Life Calculation

"Will plastic rollers or cam followers last in my application?"  We hear this question in many variations every day.

Together with a leading university Intech engineers developed a roller life cycle calculation, to reassure our customers of the reliability of Intech Power-Core rollers. This calculation includes calculation of flat development and number of expected life cycles.

The roller life calculation is based on experimental data collected in tests over a period of three years. We can say with confidence that the calculation has become a reliable predictive tool for durability of plastic rollers.

Generally, it is the static load that causes rollers - made from any material - to develop permanent flat spots. Our calculation encompasses both the static (fig.1) and dynamic (fig.2) load state.

Using this calculation we can accurately assess the life expectancy when replacing existing rollers, where the roller OD and width are dictated by existing design.
