The design must be such that it balances the need for a tight seal with the amount of friction generated during operation. Excessive friction can lead to wear and heat buildup, while insufficient sealing can allow fluid leakage. Therefore, engineers carefully select materials and dimensions to ensure optimal performance.

The hub axle seal's primary function is to keep the axle lubricated. The lubricant, often a type of grease or oil, is crucial for reducing friction between moving parts. Without proper lubrication, the components can suffer from overheating and excessive wear, potentially leading to significant damage and costly repairs. Additionally, the seal prevents water and dirt from entering the axle assembly, which can cause rust and corrosion, further jeopardizing the integrity of the axle.
Another significant advantage of galvanised garden fences is their low maintenance requirements. Unlike wooden fences that need regular treatments to prevent decay, galvanised fences only require occasional cleaning to remove dirt and debris. In most cases, a simple rinse with a garden hose is sufficient to keep them looking pristine. This ease of upkeep allows homeowners to spend more time enjoying their gardens rather than worrying about fence maintenance.
