Locking plates engage a keyway in a shaft or adapter sleeve and are attached to the side face of the nut by two bolts secured with locking wire.
A locking plate consists of a plate, two hexagonal head bolts with drilled heads and lock wire to secure them
Spacers are the small parts inserted in-between the two bearings of your skate wheel axles. They take care of the coherence between the two bearings, in order to optimize the matching and synchronization of their rotation. The bearings lean on them when tightened.

The development direction of special cables is diversified. Large-scale military enterprises shoulder the task of national modern equipment and high-tech equipment. The demand for lightweight, high-temperature cables is particularly large. The cable used in construction is mainly double-layer flame-retardant and heat-resistant wire and cable and low-smoke and halogen-free environmentally friendly wire and cable, mainly to prevent fire hazards and prevent unsafe accidents. As the energy of the mainland becomes increasingly tense, the exploitation of oil and natural gas began to turn to the sea, and thus the demand for integrated cables used in the marine sector increased. The civil aviation industry in the country is booming. Boeing aircraft use a lot of cables, among which light weight, small volume, and high temperature resistant radiation cross-linking or silane cross-linked wires and cables are used. Among the many types of special cables, the market prospects for several high-temperature superconducting power transmission cables are promising. High-temperature cables, with their strong vitality, are used in a variety of short-distance transmission of large currents, and supply exceeds demand.
In the next few years, there will be more kinds of special cables for special cables, and his role in social development and progress will also become increasingly important.
The most common model is shown on the 3D diagram below (in blue): a floating collar spacer with an axle of 8 mm.
The general use and development direction of special cables
Special cable is different from ordinary cable. Special cable can be used in special occasions, and its function is also special, such as high temperature resistance, strong acid and alkali resistance, and termite resistance. Among them, high-temperature wire and cable are mainly used in energy development, steel, aerospace, oil exploration and metal smelting and other fields. The low-inductance cable has a good heat dissipation effect. It not only has a large cooling water flow, but also does not block or limit the flow. Low-noise cables are mainly used in medical, industrial, defense, and other fields that require small signal measurement and can detect bass. There are also functionalized wire and cable and new green cables.
