Adjustable Friction Hinges have virtually no radial play.

Press Release Summary:

Offered with black or silver powder-coated, textured finish, GN 437 Zinc Die-Cast Adjustable Friction Hinges utilize plastic interlocking friction cones that are temperature resistant to 176°F to achieve friction torque. Set screw allows mobility of hinge to be changed and generates constant braking torque that is adjustable across rotating range. Rotation of doors and flaps is inhibited, preventing inadvertent movement. Hinges have virtually no radial play and no play at all in axial direction.

J.W. Winco, Inc. Offers Zinc Die-cast Adjustable Friction Hinges

NEW BERLIN, WI – J.W. Winco, Inc., a leading supplier of standard industrial machine components, announced it now offers GN 437 Zinc Die-Cast Adjustable Friction Hinges.

The RoHS-compliant hinge body is zinc die-cast, with either a black powder coated, textured finish or silver powder coated, textured finish. The friction cone, which is temperature resistant to 80° C (176° F),  is plastic, while the set screw and hexagon nut are steel, zinc plated, with a blue passivated finish.

The set screw allows the mobility of the hinge to be changed, and it also generates a constant braking torque adjustable across the entire rotating range. The rotation of doors and flaps is inhibited, preventing inadvertent movement. Interlocking two slim friction cones achieves the friction torque, as the large friction surface and the hard-wearing plastic of the friction cones guarantee a long service life with virtually no wear. Due to the structure and the pre-stress of the friction cones, the hinge has virtually no radial play and no play at all in the axial direction.

J.W. Winco offers an extensive selection of inch and metric size adjustable levers, cabinet U-handles, plastic and steel hinges and locking mechanisms, revolving and retractable handles, hand wheels, hand cranks, tube connection and conveyor components, inch and metric construction tubing, shock absorption mounts, leveling mounts, hand knobs, spring, ball and indexing plungers, jig, fixture and fastening components, retaining magnet assemblies, toggle clamps, metric casters and wheels, universal joints, oil sight glasses, and metric tools for the industrial and commercial equipment industries.
