Intech Power-Core 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 we developed a roller life calculation, to reassure our customers of the reliability of Intech Power-CoreTM 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.
