By mounting the grooved roll on a spindle, it turns on the bearing’s inner race: this enables an increase in line speed over conventional rollers by as much as +30%

Because the wire groove is not machined directly on a bearing it can have a deeper V-groove. This allows for a wider opening that greatly simplifies the stringing process

Changeover times are reduced to a fraction because the wide spacing between rollers easily accommodates the operator’s hands for manual stringing

Because wire deflection takes place by wrapping around the rollers’ outer arc, the assembly body does not need to open. This fully-rigid construction helps maintain tolerance accuracy

Micrometer adjustment of spindle cartridges allows for accurate and repeatable settings

All aspects of the assembly are precision machined, delivering measurably superior tolerance accuracy than assemblies made from cold-rolled plates
