JW Winco, Inc., a Ganter Company and supplier of standard industrial machine components, offers GN 6342 washers with axial friction bearing, stainless steel.
Used in connection with such items as Winco’s adjustable levers (GN 300 Series) or wing screws (GN 835 series) with threaded studs, the RoHS compliant washers with axial friction bearing almost double the clamping force due to lower area friction. Also, the mounting contact surface acts gently on the piece being clamped.
The washer body is stainless steel, European Standard No. 1.4305 (AISI 303) and the sliding disk is slightly greased, temperature resistant to 250 °F (120 °C), and made from Polyamide 46 glass fiber reinforced technopolymer plastic.
