Oil seals can be made from various materials, including rubber, silicone, and polyurethane. The choice of material often depends on the operating conditions such as temperature, pressure, and the type of lubricant being used. For the 50x65x8 oil seal, nitrile rubber (NBR) is commonly utilized due to its excellent oil resistance and durability in a range of temperatures.

A cooling rack, typically made of wire or metal mesh, allows baked goods to cool down evenly and maintain their texture. When you take cookies, cakes, or bread out of the oven, they may still hold onto residual heat, continuing to cook if left on a hot baking sheet. This can lead to overcooked edges or soggy bottoms—definitely not the desired outcome! By placing your items on a cooling rack, you allow air to circulate around all sides, promoting even cooling.

The design of these shelves can vary from simple wire racks to more elaborate structures with slots for each sheet. A wire rack style allows for easy visibility and access, as well as excellent airflow to aid in cooling baked goods.
