Hebei Hankai high speed rotary shaft seals

The 20x35x7 oil seal refers to its dimensions in millimeters a diameter of 20 mm, an outer diameter of 35 mm, and a width of 7 mm. This specific sizing makes it ideal for various applications that require a compact sealing solution. The oil seal is generally made from rubber or elastomeric materials, which provide flexibility and resilience against physical wear and chemical exposure. Its design often includes a metal casing, which enhances its structural integrity while facilitating installation.

2. Contamination Prevention These seals also prevent the ingress of contaminants such as dirt, dust, and moisture, which could otherwise compromise the functionality of the machinery.

Use Of Wire Mesh In Concrete

Black annealed wire is also utilized as a sheathing material in cable manufacturing. The sheathing process involves wrapping the wire around the cable to create a protective layer that shields the internal components from physical damage, environmental factors, and wear. This protective layer is vital for ensuring the longevity and reliability of the cables, especially those used in harsh environments or exposed to external mechanical forces. For example, in telecommunications and power transmission, cables often run through underground conduits or are exposed to outdoor elements. The black annealed wire sheathing helps to prevent abrasion, cuts, and other forms of damage, thereby extending the lifespan of the cables.
