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 strander bearings both have their own advantages.



CHG company is researching and developing both types of strander bearings, and has accumulated rich technical experiences. We can provide technology consultation and produtcs selection for customers in many ways.


The production and processing accuracy of CHG strander bearings all reach P5 standard ( P4 standard if required ) after the bearing is integrally designed and cage is weight lightened. The revolving speed has reached or even exceeded the same type of imported bearing. For example, the designed limit speed of 61868P53 is 2400r/min, the actual stable revolving speed in production can reach 2000r/min; the design revolving speed of 618/630P53 can reach 1100r/min, the actual stable revolving speed in production can reach 900r/min. and under full load, the strander bearing service life is about five years.
