1.Reliable durability:
Due to complicate inner structure and precise components, most multimedia products are labelled with “Handle with care” and “Guard against damp”. There also are strict standards applied on the matches among the components. Therefore, the product maintenance usually requires very professional equipments, and normally costs much. For example, IBM commercial harddisk need to go through hundreds of physical performance tests before launching, like out dropping, shocking, vibrating, pressuring and other extremely strict investigations. Such processing and analysing significantly enhance the products’ capability to survive in an extremely terrible condition, and thus well improve the data security. Once there is damage on the equipment, it may cost thousand dollars even more to run the data recovery. For the increasing demands of reliable devices, the bearings’ reliability and durability analysis for multimedia uses, become to a necessary project to the development of very top products.
For us, the capability to produce stable 450,000 rpm bearings, makes the production of lower speed modes for multimedia use become to an easy job. We therefore concentrate on the improvement of product durability. By adopting hith quality ZGCr15 materials, dedicated phenolic&textolite cages and reliable P4/ABEC 7 precision, RHD can deliver the unbeatable product durability, fully guarantee that the bearings’ service life.
2. Excellent Lubrication
The report of the bearing damage indicates that about 40% bearings are damaged due to the insufficient lubrication. It obviously has heavy impacts on the bearing’s fatigue life, friction factor, wear, working temperature and the vibration. In other words, the bearings can not be persistent working in an effective condition without good lubrication. The lubrication also can improve the heat-dissipating, corrosion resistance, sealing, and reducing external forces. In consequence, good lubrication is the key to extend the bearing’s service life.
RHD continuously worked on the bearing’s operation condition and heat-generation, moved much further in the contents of chemical composition, drop point, viscosity coefficient, and finally developed the appropriate lubrication, Based on the figures of platform tests, it has been proved that the stable lubrication can be achieved over the whole bearing’s service life.
3. Superior Low-noise
With multimedia player gradually becomes a part of our daily life, more and more customers are requesting low noise production. That leads to a huge challenge to the bearing industry due to the unavoidable vibration in the operation. The solution of low-noise multimedia player thus governs the trend of multimedia-use bearings. By sufficient fundamental researches, our specialists run through a lot of works on the noise reducing system. Now we are able to sustain the bearing’s working noise between 17dB—30dB at a “silent” condition. According to the analysis figures, RHD could further reduce 3dB via adopting the dedicated inner structure, and increasing the service life of bearings by 2 to 5 times.
