NITRILE SERIES
Nitrile Round Bellow (NRB)
» 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
» Round 1.5 Bellows cups are ideal for workpieces with uneven 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
