Oil seals work by creating a tight seal around the rotating shaft. This prevents oil and other fluids from escaping while allowing the shaft to rotate smoothly. The seal is usually made up of a lip that fits snugly against the shaft, preventing any leaks from occurring. Some oil seals also have additional features, such as springs or gaskets, to provide extra support and ensure a secure fit.

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.
