From simple hinges for welding or multi-joint hinges with complex kinematics, JW Winco offers a vast selection for high-quality door and flap solutions. The company is continually making improvements to hinges — whether that’s adding new, practical features or designing for niche applications.

Winco offers a variety of door and flap solutions, including hinges with extra functions.
For example, consider hinge GN 237.3 for heavy-duty applications. It is a compact, heavy-duty hinge made of stainless steel. With a 180° range of motion, the GN 237 can withstand high-dynamic wear, regardless of the mounting orientation. This is thanks to the use of special shim washers.
Depending on the type, the hinge bands also have centering extensions that ensure a tight fit and prevent sliding, eliminating the transverse forces that otherwise place 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 option of a third fastening hole proves its value, particularly 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. An offset axis means it can swivel by 180° without risking collision. Horizontal and vertical slots simplify adjustments and the hole pattern corresponds to existing hole arrangements, making it easier to replace the current hinges.
Winco also offers hinges with additional functionality and variable friction. For example, as part of another Winco-Norm part, an integrated spring ensures an independent return of the hinge. This special product line is continually being expanded and includes integrated damping, indexing, and locking functions. One kinematic highlight already available is the multiple-joint hinge, with either a 4x, 7x or 10x joint mechanism that opens flaps and shifts their position at the same time. The 180° feature is standard and the internal installation uses 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. It will also soon be available in stainless steel.
