1, Two generator bearings from Dongguan Lihao Bearing Co., Ltd. have successfully passed the rigorous 1000 hour test conducted by a Russian host customer.
BLH bearings and two generator bearings have successfully passed 1000 hours of rigorous testing by Russian host customers
Recently, BLH Bearing (Dongguan Lihao Bearing Co., Ltd.) has received significant good news. The company has submitted two generator bearings, BL6206-2RSM and BL609-2RSM, to Russian host customers for testing. They have successfully passed the customer's rigorous 1000 hour durability test. During the test, the bearings operated stably without any failure, and all performance indicators met or even exceeded customer expectations. With excellent quality, they have won high recognition in the international market and laid a solid foundation for the company to further cultivate the Russian market.
As a high-tech enterprise in Guangdong, BLH Bearing has always focused on the research and manufacturing of high-end bearings, strictly operating in accordance with the IATF 16949 quality management system. With world leading manufacturing processes, advanced fully automatic grinding and assembly equipment, and carbon nitrogen co diffusion heat treatment technology, the product's service life is increased by 5-10 times compared to industry standards, and the rotation accuracy reaches P4 level. Previously, BLH Bearing has served customers in 36 countries and regions around the world, and has a deep international market accumulation. The two generator bearings tested this time are core products developed by BLH factory specifically for the demand of the Russian market. They are specially adapted to the harsh operating conditions of generators and have been optimized in terms of wear resistance, impact resistance, stability, and other aspects.
It is reported that this test was led by a Russian host customer throughout the entire process, and the testing standards far exceeded the industry's conventional requirements. It simulated extreme working conditions in the actual operation of the generator and continuously tested for 1000 hours without interruption. The focus was on testing key indicators such as the fatigue life, operating accuracy, and sealing performance of the bearings - this test is a long-term durability testing standard that exceeds ordinary bearings, and is the ultimate test of the material quality, manufacturing accuracy, and structural design of the bearings. The test results showed that the BL6206-2RSM and BL609-2RSM bearings operated smoothly, without abnormal vibration or leakage throughout the entire testing cycle. All performance parameters remained stable without any signs of failure, fully demonstrating the excellent product reliability and durability of BLH bearings, and also confirming the company's research and development strength and manufacturing level in the field of generator bearings.
At present, the Russian market has a strong demand for bearing products, but at the same time faces strict market access standards and anti-dumping policy challenges. The success of this test not only breaks the quality bias of the international market towards Chinese bearings, but also becomes an important milestone for BLH bearings to break through trade barriers and deepen cooperation in the Russian market. Russian customers are highly satisfied with the test results and have clearly stated that they will further deepen their cooperation with BLH bearings to promote long-term win-win outcomes in the field of generator bearings.
BLH bearing technology engineers stated that the successful passing of rigorous testing for both products is a result of the company's adherence to the development philosophy of "quality first, innovation driven". In the future, BLH will continue to increase research and development investment, deeply cultivate the high-end bearing field, optimize product structure, enhance product core competitiveness, rely on a sound international market layout, continuously expand global cooperation territory, especially deeply cultivate potential markets such as Russia, provide reliable bearing solutions for global customers with higher quality products and services, and help promote the high-quality development of the global equipment manufacturing industry.
2, Automobile generator bearings
The bearings of automobile generators are exposed to harsh environments such as electric brush wear, dust, and external dust, mud, and water. The bearings must have good sealing performance and be able to withstand high loads by driving the generator rotor through V-shaped ribbed pulleys; With the continuous improvement of automobile performance, higher requirements have been put forward for the performance of automobile engines and generators. The maximum speed of the motor has exceeded 20000rpm, and the bearings must have ultra-high speed performance; Automobile generators require low friction torque, and the bearings of automobile generators must meet low starting and rotating torque requirements; Long lifespan, high reliability, and other requirements.
The bearings of automobile generators have the following characteristics:
1. The inner and outer rings, as well as steel balls, require materials with high purity and special treatment to obtain excellent organization; And high-precision positional tolerances, excellent working surface morphology;
2. The retaining frame material has sufficient strength to maintain high-speed and high-temperature characteristics;
3. The sealing structure and sealing components have high-performance sealing, heat and wear resistance, as well as good oil and grease inertness and stability;
4. Lubricating grease has excellent resistance to bearing fatigue peeling, high and low temperature stability, and leakage resistance.
Recommended technical requirements:
1. Oils and fats: Japanese synergistic Multemp ET-K, New Japan Petroleum ENEOS ENS, German Krupp or German Laubo anti Lubcon Turmogreate N803 oils and fats.
2. Sealing ring: Acrylic rubber (ACM).
