The head bowl bearing is a part used in many vehicles. As a kind of operating component, it often has a very large loss. In this case, it is very important to understand and avoid the loss. This issue will simply share the damage methods and related reasons.
Damage condition: When the head bowl bearing manufacturer wholesales the product under load and rotates, the inner ring, outer raceway surface or rotating body surface will show fish scale peeling phenomenon due to rotation fatigue.
Reason: The load is too large. Poor installation, torque load, foreign matter intrusion, water ingress. Poor lubrication, inappropriate lubricant, inappropriate bearing clearance. The bearing box has poor accuracy, uneven rigidity of the bearing box, large shaft deflection, rust, corrosion points, scratches and embossing.
Countermeasures: Check the load size and re-examine the bearing used to improve the installation steps, improve the sealing device, and prevent rust when shutting down. Use lubricants with appropriate viscosity and improve lubrication methods. Check the accuracy of the shaft and bearing box. Check the side clearance.
Damage condition: The customized effect of the head bowl bearing of the modular type shows a dark surface with slight wear. The dark surface has multiple small gaps from the surface to the inside, with a depth of 5-10m, and small shedding occurs in a large scale.
Reason: The lubricant is not suitable. Foreign matter enters the lubricant. The poor lubricant causes the surface to be rough. The surface gloss of the matching rotating parts is not good.
Countermeasure: Select lubricant to improve the sealing device to improve the surface gloss of the matching rotating parts.
Damage condition: The so-called jamming commonly seen in the customization of motorcycle head bowl bearings is the surface damage caused by the combing of some small burns caused by the sliding surface. Strip scars on the guide surface and the rotating surface circle. The swing strip scars on the roller end face are close to the jamming of the shaft ring surface of the roller end face.
Reason: Too much load, too much preload. Poor lubrication. Foreign matter biting in. Inclination of the outer side of the inner ring, shaft deflection. Poor precision of the shaft and bearing box.
Countermeasures: Check the load size. Preload as much as possible. Improve lubricants and lubrication methods. Check the precision of the shaft and bearing box.
Damage condition: The so-called cracking refers to the cracking of a small part due to the impact or excessive load on the rib of the raceway wheel or the part of the roller angle.
