You might think that when it comes to opening and closing, all the possibilities of hinges have already been exhausted. Not even close. Winco regularly succeeds in making further improvements to hinges, adding practical extra features or creating designs for very particular niche applications.
For heavy duty applications, for example, try hinge GN 237.3, a compact, heavy duty hinge of stainless steel. With a 180° range of motion, these hinges can stand up to even high dynamic wear—regardless of the mounting orientation—thanks to special shim washers. Depending on the selected type, the hinge bands also have centering extensions that ensure a tighter fit—preventing sliding and eliminating the transverse forces that otherwise place extremely heavy loads on the screws. The hinge pin is secured against loss by a recess and supplied with lifetime lubrication. An asymmetrical band arrangement and the associated possibility of a third fastening hole proves its value especially when mounted in areas with thinner material cross-sections.
The hinge series GN 235, on the other hand, can be mounted with socket head cap screws and—thanks to
the offset axis—still swivels by 180° without collision. Horizontal and vertical slots simplify adjustment, and
the hole pattern corresponds to existing hole arrangements, making it easier to replace existing hinges.
Hinges from Winco
Additional functionality is offered by hinges with variable friction, and in another Winco-Norm part, an integrated spring ensures independent return of the hinge. This special product range, which also includes integrated damping, indexing and locking functions, is being continually expanded by Winco. One kinematic highlight is already available from Winco: the multiple-joint hinge with either a 4x, 7x or 10x joint mechanism, which opens flaps and shifts their position at the same time. 180° is also standard here, and the internal installation once again makes use of slots.
With its design hinges GN 138, Winco offers solutions for appearance-sensitive applications: the closed hinge body of die-cast zinc hides the fastening screws and is available in various sizes—soon also in stainless steel.
