Hebei Hankai hydraulic ram rebuild kit
The hydraulic cylinder oil seal is typically made of rubber or other synthetic materials that are resistant to hydraulic fluid and capable of withstanding high pressure and temperatures
. The seal is carefully designed to provide a tight fit between the moving parts of the cylinder, such as the piston and the cylinder walls, to prevent any fluid from leaking out. Without a proper oil seal, hydraulic fluid could leak out of the cylinder, leading to a loss of pressure and potentially damaging the entire hydraulic system.hydraulic cylinder oil seal

This particular oil seal is designed to accommodate a shaft diameter of 50mm while sealing against a housing with an outer diameter of 90mm, ensuring tight closure and effective sealing. The 10mm width is optimal for creating a sufficient sealing surface to prevent leakage while maintaining a low profile in installations.

One of the primary factors influencing the price of oil seals is the cost of raw materials. Oil seals are typically made from a combination of rubber, plastics, and metals, all of which have their own price volatility. For instance, the cost of synthetic rubber can change dramatically based on the price of crude oil, as it is a petroleum-based product. When oil prices rise, manufacturers may face higher production costs, which they often pass on to consumers. Furthermore, geopolitical tensions or natural disasters can disrupt the supply chain, leading to increased raw material costs and, subsequently, higher oil seal prices.
