Type B - with bores for countersunk screws and centering attachments
GN297.3 Heavy Duty Hinges
Horizontally elongated, stainless steel, heavy duty hinges GN 237.3 are designed for use under tough conditions. Attachment points with a wider spacing and more installation holes allow a more effective introduction of force into the mounting surface. The hinge pins are integral and allow the hinges to be used in environments with strong vibrations and shocks.
The selected materials allow the hinges to be used in aggressive environments. Wear is minimized by the effective friction pairing of the hinge components and lubrication.
The type B hinge has centering attachments that prevent lateral slippage under high loads and protect the mounting screws from impermissible transverse force.
