Hebei Hankai 40x55x8 oil seal
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.

Moreover, modern materials and technologies allow for a variety of functionalities in bike rack design. Some custom racks feature integrated locking mechanisms, ensuring that bikes remain secure while owners are away. Others include built-in maintenance stations where cyclists can perform minor repairs or inflate their tires. These added functionalities promote a culture of cycling by addressing common concerns cyclists face in urban settings.
