Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.

Oil seals are typically made of rubber or synthetic materials that are resistant to oil, heat, and pressure. They are designed to withstand the harsh conditions within an engine or machinery, such as high temperatures and varying levels of pressure. The seal is usually placed in a housing or a groove in order to effectively seal the gap between two moving parts.

2. Walking Foot A walking foot, or a feed dog system, can be invaluable when sewing fur and leather. This feature helps to feed the materials evenly through the machine, minimizing the risk of shifting. It works by moving the upper layer of the fabric in sync with the feed dogs beneath, which is particularly useful when working with slippery and bulky materials.
