Research and Design for Precision Bearing | FDB Motor

Home R&D

Jialian Technology has developed micron-level Herringbone Precision Fluid Dynamic Bearing (HGFDB) with professional technology and also has developed a unique machine for mass production of HGFDB. The production of HGFDB requires a high-precision processing machine. The process is special and high cost. We make the machines by ourselves, so we can increase the production capability quickly. Jialian Technology specializes in researching the precision structure of the sintered oil-impregnated bearings and the dynamic circulation system of the lubricant, thereby obtaining the best quality of the high-lubrication and low-friction design. The inner diameter of HGFDB have four sizes currently: 1.2mm, 1.5mm, 2.0mm, 3.0mm. The outer diameter sizes are 4.0mm, 5.0mm, 8.0mm. The other specifications are under development. If you want to pursue quietness, long life, good for high-speed rotation, high quality, and reduce cost for the rotator of your products, HGFDB will be the best choice.

The precision requirements of Herringbone Groove Fluid Dynamic Bearing (HGFDB) are extremely high which must reach micron level. The precision of its processing equipment must be higher. In addition, the processing of the herringbone grooves is special. There was no ready-made equipment on market at that time. For this reason, it is necessary to develop a processing machine by ourselves, though costly. After years of research and development and test, Jialian Technology has overcome difficulties and mastered the technology of manufacturing, production, and processing equipment. Jialian Technology can arrange production smoothly now. In addition, we can rapidly reach the needs of expanding market in order.

At the same time, we have also established Bearing Application Laboratory and Accelerated Life Laboratory for testing, verification, and statistical analysis of fluid dynamic pressure in bearings and product applications-related issues. According to the ISO9001 quality management system and international industrial and environmental standards to provide complete quality assurance. Jialian Technology has invested a lot of energy and manpower in product development, inspection and testing, analysis and improvement, production equipment development and standard system establishment, and successfully launched products of Herringbone Groove Fluid Dynamic Bearing series. Solving the problem of short-life oil leakage of traditional copper bearings and the high-price and the noise of ball bearings in one fell swoop. It can not only help extend bearing's life but also has a better ability to reduce vibration and noise. In addition, Jialian Technology has obtained a number of international patents such as bearing and processing equipment as listed above to ensure that customers can use them with confidence.

Product Development

Jialian Technology uses exclusive formula lubricating oil in Herringbone Groove Fluid Dynamic Bearing (HGFDB) which is the most suitable for the precision structure of sintered bearing. The lubricating oil forms a dynamic circulation system between shaft and bearing during operation to obtain the best quality of high lubrication and low friction. Quiet, long-life, suitable with high-speed rotation, and low-cost HGFDB is your best choice. The bearings are thoroughly tested before offering the market to ensure the best reliability.

Countries all around the world are concentrating on the issues of global warming and environmental pollution. In the production process, HGFDB doesn’t produce waste and pollution and doesn’t contain regulated toxic substances. All materials comply with the international environmental protection standards of RoHS (Restriction of Hazardous Substances).

The inner diameter of HGFDB products has four sizes currently: 1.2mm, 1.5mm, 2.0mm, and 3.0mm. The outer diameter sizes are 4.0mm,5.0mm, and 8.0mm. The other specifications are under development. If the rotating parts in your product want to pursue quietness, long-life, high-speed rotation, quality improvement, and cost down, HGFDB will be the best option.

Equipment Development

The precision requirements of Herringbone Groove Fluid Dynamic Bearing (HGFDB) are extremely high which must reach micron level. The precision of its processing equipment must be higher. In addition, the processing of the herringbone grooves is special and without any ready-made equipment available. It is necessary to develop Jialian-made machines, which make production equipment very expensive. After years of research and development and test, Jialian Technology has overcome difficulties and totally mastered the technology of independent design, manufacturing, production, and processing equipment. Jialian Technology can arrange production smoothly now. In addition, we can rapidly reach the needs of expanding market in order.
