Customized Thrust Ball Bearing

The engineering game behind bearing contact formsDeep within modern industrial systems, a small yet crucial design choice often determines the lifespan and reliability of an entire piece of equipment. Bearings, the core fulcrum of rotating machinery, depend on the contact pattern between their rolling elements and raceways—whether it's "point" or "line"—to quietly impact the operational safety of everything from wind turbines to steel rolling mills.Industry data shows that nearly 90% of premature bearing failures are not due to manufacturing defects, but rather to misjudgment of contact type during the selection phase. This seemingly minor difference can quickly evolve into a systemic failure in real-world operating conditions, resulting in costly downtime and replacement.On a laboratory's extreme test bench, a pair of identical bearings are subjected to progressively increasing loads. On one side is a deep-groove ball bearing with steel balls, and on the other is a roller bearing. As the pressure increases, the monitoring system records distinct response curves: the roller bearing exhibits greater rigidity under heavy loads, while the ball bearing, while flexible under light loads and high speeds, is the first to show signs of fatigue under the combined stresses.This difference stems from the inherent contact configuration.In ball bearings, the rolling elements and raceways form a tiny elliptical contact area, theoretically representing "point contact." Roller bearings, on the other hand, achieve "line contact" through cylindrical contact, resulting in a larger load-bearing area and lower unit stress. However, the complex mechanical environment often separates ideal models from real-world operation.A real-world example reveals the cost of misuse. A wind turbine main shaft suddenly began making unusual noises less than halfway through its design lifespan. Disassembly revealed numerous micron-scale spalling pits on the inner race of the bearing. Electron microscope observation revealed patterns resembling butterfly wings—typical subsurface fatigue damage. Analysis revealed that the point contact structure, under the combined effects of long-term alternating stress and slight deflection, had quietly developed a network of cracks within it, ultimately leading to surface spalling.At another steel mill, infrared thermal imaging of rolling mill bearings revealed localized temperatures exceeding 200°C above the surrounding area. Further testing confirmed that due to inadequate consideration of shaft deformation, the normally evenly distributed linear contact area was compressed into an extremely narrow rectangular band. This resulted in a sharp increase in stress at the ends, causing "edge collapse" and rapid material degradation.

WXING Bearing, a leading name in the global bearing industry, cordially invites its valued partners and clients worldwide to visit its booth at the 138th China Import and Export Fair (Canton Fair). We are excited to showcase our latest innovations and high-quality products at Booth No. 19.1D27 from October 15th to 19th, 2025.A Legacy of Quality and Innovation, Forged Over DecadesThe WXING story is one of passion, perseverance, and family legacy, beginning in the very heartland of China's bearing industry.The Humble Beginnings (1995): Our journey started in 1995 in Yandian, Shandong Province – known as "The Township of Bearing in China." Jack Lee's father, alongside family members, established a small factory, laying the foundational dreams and expertise that would define our future.Establishing a Foundation (2000): Through relentless effort, the family founded the Linqing Shengli Factory in 2000. As the third factory in Linqing town, it began independent production and supply to local industries. It was here that a young Jack Lee gained firsthand experience on the production floor, learning the intricacies of bearing manufacturing from the ground up.Scaling New Heights (2005): Rapid growth led to the construction of a new, expansive 25,000 square meter workshop in 2005. This era marked a significant technological leap with the introduction of state-of-the-art equipment, imported production technologies, and stringent quality standards, positioning the company as a reliable, high-quality supplier across China.Going Global (2010): Embracing a new vision, Jack Lee founded Jiaxing Waye Bearing Co. Ltd. (now Zhejiang Waxing Electromechanical Co., Ltd.) to expand into the international market. Under the registered brand "WXING," the company began its global ascent. Today, WXING bearings are trusted in over 100 countries, with annual sales exceeding USD 10 million.Visit Us at Canton Fair – Booth 19.1D27At this year's Canton Fair, we are proud to present the culmination of our decades-long journey.

Characteristics and causes of bearing grinding cracksGrinding is a common metal cutting process in the machinery manufacturing industry and is also widely used in the bearing processing industry. During the grinding process, heat-treated and quenched bearing parts may develop a network of cracks or regularly arranged fine cracks, known as grinding cracks. These cracks not only affect the appearance of bearing parts but, more importantly, directly impact their quality. This article discusses the characteristics and causes of bearing grinding cracks, as well as preventative measures.

The hidden truth behind the "abnormal sonata" of bearings1. Lubrication factorsLubrication is as important to bearings as blood is to the human body. When lubrication is insufficient, an effective lubrication film cannot be formed at key friction points such as between the rolling element and raceway, between the cage and the rolling element inside the bearing, and the metal surfaces are in direct contact, causing the friction coefficient to increase dramatically. This dry friction between metals will generate a lot of heat, accompanied by a sharp "squeaking" sound, like the sound of scratching a blackboard with fingernails, which is very irritating. For example, in some high-temperature, high-speed mechanical equipment, if the grease is not replenished in time, the lubrication state of the bearing will deteriorate rapidly, and abnormal rotation noise will also appear.2) Installation problemsInstallation is a key link to ensure the normal operation of the bearing. Any slight improper installation may become a hidden danger of abnormal rotation noise. Installation eccentricity is a common problem. When the bearing is not accurately aligned with the shaft or bearing seat during installation, the force inside the bearing will become uneven. Some rolling elements are under pressure, while other parts are underloaded. This uneven force state will cause the movement trajectory of the rolling elements on the raceway to deviate, generate additional friction and vibration, and emit an abnormal "clicking" sound.3) Quality defectsThe quality problem of the bearing itself is also an important reason for abnormal rotation noise. Material defects are a manifestation of quality defects. For example, during the production process of the rolling element or ring of the bearing, if there are defects such as pores, sand holes, inclusions, etc. inside the material, these defective parts are prone to stress concentration when bearing loads, resulting in a decrease in the strength of the local material. As the bearing runs, these weak parts will gradually develop cracks, peeling and other damages, resulting in abnormal rotation noise. In order to reduce costs, some small manufacturers do not strictly control the purchase of raw materials and use poor quality steel, and the bearings produced are prone to such problems.4) Overload operationBearings are designed with a rated load capacity. When the equipment is in an overloaded state for a long time, the actual load on the bearing far exceeds its rated load. This will cause excessive pressure on the parts inside the bearing, resulting in a sharp increase in the contact stress between the rolling element and the raceway, and increased surface wear. As wear continues to develop, the clearance of the bearing will gradually increase, the stability of the internal structure will be destroyed, and abnormal rotation noise will be generated. On the production lines of some factories, in order to pursue output, the equipment is in a high-load operation state for a long time. The bearing is subjected to excessive pressure for a long time, and abnormal noise will soon appear, shortening the service life of the equipment.
