dust sealing
This particular oil seal is designed to accommodate a shaft diameter of 50mm while sealing against a housing with an outer diameter of 90mm, ensuring tight closure and effective sealing. The 10mm width is optimal for creating a sufficient sealing surface to prevent leakage while maintaining a low profile in installations.

A baking sheet, also known as a cookie sheet or baking tray, is a flat metal pan used in an oven to bake a variety of items, from cookies and pastries to roasted vegetables. The material of the baking sheet matters; aluminum sheets conduct heat evenly, allowing for uniform baking, while dark-colored sheets can absorb more heat and may lead to quicker browning of baked goods. It's essential to choose the right baking sheet for the task at hand. For example, for delicate cookies that require gentle heat, a light aluminum sheet is often preferable, while for items that benefit from a crispy bottom, such as pizza, a darker sheet may be more suitable.
