Furthermore, dust wiper seals help maintain the seal integrity of a system, preventing leaks and ensuring that pressure and fluid levels remain consistent. By creating a tight seal between moving parts, these seals help prevent air and fluid from escaping, which can lead to performance issues and system failure. In hydraulic systems, for example, leaks can result in a loss of power and efficiency, increasing the risk of equipment failure and downtime. Dust wiper seals help prevent these issues by maintaining a secure seal and keeping contaminants at bay.

A skeleton oil seal, also known as a metal casing seal or a rubber oil seal with a metal reinforcing ring, consists of an elastomeric material molded around a metal skeleton. This design provides enhanced stability and durability compared to traditional oil seals. The metal skeleton not only supports the seal but also adds structural integrity, allowing it to withstand higher pressures and temperatures.

In the 18^th century, although usually made from wood, bedframes also started to be constructed using metal. Mattresses were stuffed with cotton and maids and personal valets no longer slept on trundles on the floor. The bed was not used for receiving visitors, but rather as a private space. In the 19^th century, the four-poster beds were less lavish, and metal bedsprings were invented. It was during the 20^th century when the water bed was created, as well as the air, innerspring, and memory foam mattresses, and now in the 20^th century, we are spoilt for choice!
