Expanded metal grating is also highly customizable, allowing for tailored solutions that meet specific project requirements. It is available in various materials, including steel, aluminum, and stainless steel, making it suitable for different environmental conditions. Each material has its unique properties, such as corrosion resistance (in the case of stainless steel) or lightweight flexibility (as seen with aluminum), enabling engineers and architects to select the most appropriate option for their projects.

The perfect remedy for this is to use oil seal materials that are rated for the temperature of your application. Also, ensure that the elastomer is free from volatile constituents like waxes, plasticizers, etc.
Temperature:
Another type of seal design has the metal encased in rubber (Figure 2.11).

Oil seals made of HNBR are characterised by excellent properties that include high resistance to mineral oils with additives, low steam and gas permeability, good cold flexibility down to -30 °C depending on type, good ozone resistance and friction resistance. HNBR seals withstand heat up to 150°C.

The skeleton oil seal structure consists of three parts: the oil seal body, the reinforced skeleton and the self-tightening coil spring. The sealing body is divided into bottom, waist frame oil seal structure diagram, cutting edge and sealing lip according to different parts. Generally, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain interference. Therefore, after the oil seal is installed on the oil seal seat and the shaft, the pressure of the oil seal edge and the contraction force of the self-tightening coil spring will produce a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease or even disappear. , Therefore, adding a spring can compensate for the self-tightening force of the oil seal at any time.

Nitrile (also known as Buna N)
Most ERIKS oil seals, such as the types M, MST, R and RST, are made of NBR as standard.
