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

With fast development of electronic and computing technologies and methodologies in the last 20 years, the speed controlling technique applied in the electrical motor industry had great improvement. For precise CNC machinery, numerous wide-range speed regulated DC motors were replaced by permanent magnet synchronous brushless AC motors, particularly in robots and mechanical arms.

To maintain motors at proper operating condition, there are several crucial components require regular maintenance. Bearings, certainly to say, should be the top of the importance, which coupling most mechanical operations. As such a critical element, its… Read the rest
