Abstract
A toggle clamp unit of a plastic processing machine, especially of an injection molding machine, including a front plate and a crosshead which is arranged movable relatively to the front plate in a direction of closing, wherein at least two levers are supported articulated at the front plate, wherein the at least two levers are each connected articulated with at least one link which links are supported articulated at the crosshead and wherein the crosshead is provided with at least one linear bearing by which the crosshead is movably supported relatively to the front plate in the direction of closing. To design the linear bearing very smooth-running and to reduce the requirement of lubrication the invention proposes that the linear bearing is designed as a roller bearing.
