1. P4/ABEC7 and P2/ABEC9 precision;
By employing the most advanced techniques, RHD now is able to apply P2/ABEC9 & P4/ABEC7 production, fully achieving world-class standards.

2. 20dB-30dB low-noise world-class operating condition:
RHDs motor bearing series now is able to stably stay in 20dB-30dB at 60, 000 rpm, and even can achieve 17dB standard for customized products.

3. Finest military high carbon chrome bearing steel - ZGCr15:
RHD adopts military high carbon chrome bearing steel (ZGCr15) which contains particular low oxygen composition. We also take strict controls on harmful composition such as P and S etc. To cast ZGCr15, we need to run through the latest improved electroslag remelting techniques, purifying the metal contents into pure & compact structured steel ingots. Its high consistency, fine and even granular crystals greatly improve the mechanical properties, assist the bearings be able to withstand very heavy loads and deformation-resistance, subsequently make the bearings service life significantly longer.

4. Top Textolite-based phenolic Cage:
RHD bearing adopted the textolite-based phenolic material which could only be provided by few suppliers in the world. By adopting textolite-based phenolic cage, plus P4/ABEC7 precision, our bearing can reach 60, 000rpm rotating speed at 20-30dB. The material also has the following properties, such as high temperature resistance, corrosion-resistance, self-lubrication, and so on.
