1. Dedicated Measurement Equipment for Critical Parameters:

High-precision dynamic radial and axial clearance;
Precision bearing inner/outer ring rotation accuracy including inner/outer diameters and end vibration (dynamic measurement, conforms to national evaluation standards). Repeat accuracy is within 0.6μm – 1.5μm;
Precision bearing rigidity (optimizing structures by preloading and then measuring end face convex border). Air shaft loaded, the repeatability is within 1~2μm);
Matched bearing dynamic and static friction moments (of single bearings). The stability value of the air spindle shaft (support and rotary component) is 0.5mN·m/4h;
Bearing vibration (acceleration and… Read the rest

As a leading player in the bearing industry, RHD’s motor bearing series has below outstanding features:
1. P4/ABEC 7 and P2/ABEC 9 precision:
With the emergence of new materials like rare earth permanent magnet Nd-FE-B and magnetic composite materials, more and more high-performance motors are appearing on the market. That also results in a great demand of top quality bearings. Since adopting dedicated cages and precise processing, the friction factor can be decreased significantly and therefore enhancing the rotating speed and service life. Such bearings are widely used for… Read the rest

1.Real 450,000 rpm operation speed:
Dentist has recognised that the pains during treatment could be reduced significantly if the drill bit be able to reach an extremely high rotating speed. As far as the… Read the rest

RHD Bearing Co., Ltd has years of research experience in manufacturing precise machine tool bearings, and our products have the following outstanding features:
1. Ultra-accuracy – P4/ABEC 7 for spindles.
For most small equipments like mini-motors, wheel gearing systems, cam gears, generators, high sensitivity servo motors, pressure rotors, printers and photocopiers, regular bearing’s precision would be good enough for uses. However, in the case of machine tool spindles, the bearing’s precision becomes to a key issue influencing the overall performance and stability. Although P5/ABEC 5 bearings are ubiquitous in Asia,… Read the rest
