Winco, a manufacturer of standard parts and ganter company, provides a number of specialty hinges. For heavy duty applications, the company has created the GN 237.3, a compact, heavy duty hinge of stainless steel. Designed to have a 180° range of motion, these hinges are made to stand up to high dynamic wear—regardless of the mounting orientation—because of special shim washers the company has integrated.
Depending on the selected type, the hinge bands also have centering extensions that are meant tp ensure a tighter fit—preventing sliding and eliminating the transverse forces that otherwise place extremely heavy loads on the screws. The hinge pin is designed to be secured against loss by a recess and supplied with lifetime lubrication. An asymmetrical band arrangement and the associated possibility of a third fastening hole are available for mounting in areas with thinner material cross-sections.
Another product, the hinge series GN 235 is meant to be mounted with socket head cap screws and with the offset axis is supposed to still swivel by 180° without collision. Horizontal and vertical slots are meant to simplify adjustment, and the hole pattern should correspond to existing hole arrangements, in order to make it easier to replace existing hinges.
Additional functionality is offered by hinges with variable friction, and in another Winco-Norm part, an integrated spring is meant to ensure independent return of the hinge. This special product range—which also includes integrated damping, indexing, and locking functions—is being continually expanded by Winco, says the company.
One kinematic highlight that is available from Winco is the multiple-joint hinge with either a 4x, 7x, or 10x joint mechanism, which is designed to open flaps and shift their position at the same time. 180° is also standard here, and the internal installation once again makes use of slots.
A last product series is the design hinges GN 138. Winco offers systems for appearance-sensitive applications through this series. The closed hinge body of die-cast zinc is made to hide the fastening screws and is available in various sizes, soon also in stainless steel.
