hydraulic oil seal material

Oil seals are generally constructed from materials that can withstand the specific chemical properties of the lubricant they are sealing. Common materials include rubber, silicone, and various elastomers. The design of an oil seal often incorporates a lip that rolls against a shaft or surface, creating a dynamic seal that can accommodate movement while maintaining its sealing capabilities.

A boom cylinder seal kit is a collection of various seals and components designed to maintain the integrity of hydraulic cylinders, specifically those used in booms of excavators, cranes, and other machinery. The primary purpose of these seal kits is to prevent hydraulic fluid leaks, ensuring that the hydraulic system operates smoothly and efficiently. The kits typically include O-rings, piston seals, rod seals, and backup rings, each designed to withstand high pressure and temperature conditions inherent in hydraulic operations.

Moreover, heavy machinery, such as excavators and loaders, employs these oil seals to protect hydraulic systems and ensure efficient operation. Given the rigorous conditions these machines operate under, high-quality oil seals are imperative to prevent costly downtime and repairs.

This is one of the frequent reasons for oil seal failure, and this is majorly because of the volatility of any of the elastomer’s constituents. These causative constituents may be part of the elastomer formulation, or gases that got entrapped in the elastomer during the molding process. The deceiving fact about this failure is that sometimes the oil seal won’t show any visual sign of out-gassing, however, sometimes when the out-gassing is extreme, they shrink.
