Oil seals come in various designs depending on the specific requirements of the machinery. The 20x30x7 oil seal, for example, is a standard radial shaft seal that is installed along the shaft to prevent oil from leaking out or contaminants from entering the machinery. This type of seal is commonly used in engines, gearboxes, and other rotating equipment where the sealing of fluids is essential.
When comparing durability, cylindrical roller bearings generally have a higher capacity for load carrying due to the larger contact patch between the roller and races
cylindrical roller bearing vs ball bearing. However, they may not perform well under impact loads or high-speed applications because of their design. Ball bearings, while capable of handling combined loads, may not withstand extremely heavy radial loads as effectively as their cylindrical counterparts.
