In the manufacturing sector, high temperature oil seals are used in machinery that processes materials at high temperatures, such as extruders and injection molding machines. In the oil and gas industry, they play an essential role in ensuring the reliability of pumps and compressors operating in high-temperature environments. These seals are also utilized in power generation systems where steam and thermal energy processes involve significant temperature fluctuations.

Oil seals, also known as shaft seals or rotary seals, are essential components widely used in various mechanical systems to prevent the leakage of lubricants and the entry of contaminants. The dimensions of oil seals are typically presented in a format indicating the inner diameter, outer diameter, and width. For example, the 35x52x7 oil seal has an inner diameter of 35 mm, an outer diameter of 52 mm, and a width of 7 mm. This article delves into the significance, construction, and applications of 35x52x7 oil seals.

1. Material Composition The price of hydraulic cylinder oil seals is significantly affected by the materials used in their manufacturing. Common materials include nitrile rubber (NBR), polytetrafluoroethylene (PTFE), and polyurethane (PU). Each material has its unique properties, such as temperature resistance, chemical compatibility, and durability, influencing the overall cost. High-performance seals made from premium materials tend to be more expensive but can offer longer lifespans and better resistance to harsh conditions.

The design of the lip is crucial; its profile allows it to make optimal contact with the shaft, creating a seal that can accommodate the shaft's rotation. Some rotary lip seals also include a dust lip or exclusion barrier, which helps protect the primary sealing lip from contaminants such as dirt and debris.
