Hinge bushing with wires Tefcold SpareParts 12786

A bushing in a refrigeration door hinge carries the mechanical load of the door while maintaining an electrical path. The hinge pin passes through the bushing, which is pressed into the hinge leaf. When the door opens or closes, the bushing prevents metal-to-metal wear and keeps the hinge aligned. On models that integrate lighting, defrost heaters or door switches, the bushing also contains small-diameter wires that bridge the hinge halves, ensuring the circuit remains unbroken regardless of door position.

The operator does not interact with the bushing directly; it is fitted during hinge assembly or repair. Once installed, the bushing remains in place until the hinge is disassembled for maintenance or replacement. The wires are crimped or soldered to terminals on each hinge leaf, so no additional connection work is required beyond securing the hinge to the cabinet and door.

This bushing is manufactured as a single moulded unit combining a polymer sleeve and the embedded conductors. The polymer provides the bearing surface and electrical insulation between the hinge pin and the metal leaves, while the wires carry the low-voltage signal or power across the hinge joint.

Tefcold SpareParts article 12786 is a direct replacement for the original bushing on Tefcold commercial refrigeration and freezer cabinets that use electrically continuous hinges. It fits models where the door wiring must pass through the hinge without interruption.
