GN 237.3-A4-B Heavy Duty Hinges For particularly aggressive environments, with bores for countersunk screws and centering attachments

Horizontally elongated 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 material of the hinge leaves (Version NI) is very robust and, thanks to the martensite structure, is suitable for use in aggressive environments, albeit subject to some restrictions. The heavy-duty hinges (Version A4) can also be used in particularly aggressive environments thanks to the materials used. 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.
