TASK roll shells, available in several patterns, are designed to match the excellent performance of its dies. Roll shells operate under extremely harsh conditions. Therefore, it is vital that the dimensions are accurate and the hardening process is of the highest standard. TASK will assess your needs and help select the correct design for the application.

Our roller shells are manufactured in the following steels:

●40Cr (normal alloy steel)

●20CrMnTi (“alloy steel” or “20MnCr5)

●100Cr6 (“bearing steel”)

The roller shells are case hardened.

The heat treatment achieves 58-62HRC harness for 1.2-1.5mm depth.

Roller Shell Surface Types as follows:

●Fluted End Closed           ●Fluted End Open

●Fluted End Dimple          ●Dimple 

●Helical Fluted
