- Skeleton oil seals are typically made of rubber or metal, with a spring-like structure that allows them to be flexible and adapt to the movement of the machinery. They are often placed in housing units or mounted directly onto the rotating part to ensure a tight seal.
The speed at which an oil seal can operate effectively depends on the previously outlined conditions together with the design of the seal itself. Some designs allow for a range of maximum peripheral speeds and are therefore more suitable for larger shaft diameters. Speeds below and above the recommended range can cause friction and thus impact the sealing material.

Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.

Trailer hub oil seals play a critical role in maintaining the integrity of the wheel hub assembly on trailers and other towed vehicles. These seals are designed to prevent the leakage of lubricating oil and the ingress of contaminants, ensuring the proper functioning and longevity of the wheel bearings and other internal components. The trailer hub oil seal is typically positioned within the hub assembly, creating a barrier that helps retain the lubricant and protect the bearings from moisture, dirt, and debris.
