shell (n)

A grab comprises two jaws (also called clamshells) usually made of steel that are connected on one side to a hinge in a way that enables rotation.

Once the melt has been poured into the mould, solidification can be straight-walled, rough-walled and sponge-like (exogenous solidification) or shell-forming (endogenous).

In conjunction with the End Cap and Lubricating Systems, the Roller Profile acts as a bearing shell and safety cover, as well as providing protection against soiling.
