Which of the following is an advantage of a QD bushing?

A QD (Quick Disconnect) bushing is designed for ease of installation and removal, which is a key feature that distinguishes it from other types of bushings. The ability to remove a QD bushing easily with a bearing puller is a significant advantage because it greatly simplifies the maintenance process. This quick removal capability allows for efficient replacement or adjustment without the need for extensive disassembly of surrounding components.

Furthermore, using a bearing puller reduces the risk of damage to the surrounding equipment, which can occur with more rigid or complex bushing designs. This can save time and costs in labor during repairs.

In contrast, while lower installation cost, greater torque capacity, and higher resistance to wear are important factors in mechanical design, they do not specifically pertain to the unique benefits that a QD bushing offers. Therefore, the most compelling advantage highlighted here is indeed its compatibility with bearing pullers for easy removal, enhancing maintenance efficiency.
