D490 Differential Shafts hold rolls straight and true. Interchangeable cartridges allow you to determine how the shaft engages the core to best suit the material and core you’re running. Choose from a heavy gauge wire spring design (D490S) for fiber cores, or a 2-row, 12-ball, torque activated design (D490B) for fiber or PVC cores.

The result is improved finished roll quality, reduced scrap and fast, easy setups for even the most sensitive materials. Because D490 Differential Shafts are manufactured in North America, Europe and China, they are easily sourced and supported worldwide. All components conform to Tidland’s high quality standards and are interchangeable regardless of where the shaft is installed.
