NITRILE SERIES
Nitrile Oval Bellow (NOB)
» Large stroke and great flexibility, easy to fit close to workpiece with various shapes
» Large inner support structure to protect the sheet metal from deformation and damage during
handling process
» Tread pattern efficiently increases the friction force between cups and workpiece in order to
prevent the oily metal sheets from slipping during the handling process
» Available in 60 durometer material
» Ideal for sheet metal with different thickness and shapes
» Oval 1.5 Bellows cups are ideal for workpieces with uneven rectangle shapes
Application
» Ideal for sheet metal handling including oily stamping applications
» Ideal for parts with uneven surface
» Applicable for glass, plywood and other stamping materials
