At the beginning when CHG Bearing designs and develops strander we were targeting at the import standards. After the development of more than a decade our company has developed 61868, 61880, 61892, 61896, 618/530, 618/630, 618/750, 618/850, 618/980 which have gain recognition and received positive evaluation among our customers. Currently the strander bearing in our company has formed our own features: high speed, high accuracy, long life, low vibration and low noise.
Currently the domestic High-speed Tubular Strander Bearing basically adopts 618 series while the same foreign equipment is inclined to choose N18. These two series of bearings have their own advantages. CHG bearing is researching and developing both and has accumulated mature technology. We can provide technology consultation and products selection for customers in many ways.
