[0002] A bearing housing is a device used to support and protect bearings and is typically installed on the rotating shaft of a machine. The primary function of a bearing housing is to provide a stable mounting environment for the bearings, ensuring their proper operation while protecting them from contamination and damage. Bearing housings are typically made of metal, offering strength and rigidity to withstand loads and shocks. When designing a bearing housing, factors such as the bearing type, size, operating conditions, and lubrication method must be considered to ensure performance and lifespan. Bearing housings come in a variety of configurations, including vertical, horizontal, and suspended types, suited to a variety of applications.

[0003] When disassembling or assembling the bearing housing, multiple bolts are usually used to firmly fix the bearing or sealing cover to the bearing housing.

[0004] However, when these bolts experience thread stripping, disassembly becomes extremely difficult. Thread stripping occurs when the bolt threads become damaged during force application, preventing the bolt from rotating properly and causing it to loosen. This condition not only makes disassembly extremely difficult but can also cause further damage to the bolt and screw hole.

[0005] Furthermore, the large number of bolts that need to be removed not only significantly increases the time required for disassembly, but also makes the entire disassembly process more tedious and complicated. Each bolt needs to be handled individually, which is not only labor-intensive but may also require the use of special tools and techniques to cope with different disassembly situations.
