1. Lubrication Retention The primary function of a grease seal is to retain the lubricating grease within the bearing. This grease is crucial for reducing friction, minimizing wear, and ensuring that the bearing operates smoothly. When grease escapes, the bearing can run dry, leading to overheating and potential failure.

The complexity of the manufacturing process also plays a significant role in determining the price of oil seals. Production involves several steps, including material preparation, molding, and quality control. High-precision seals that are engineered for specific applications typically come at a higher price point due to the advanced technology and expertise required in their production. Manufacturers with stringent quality control measures may also incur higher operational costs, which can be passed on to consumers through increased prices.
