Essence of life is versed in development goes roller bearing of low noise low vibration
Origin: Global mechanically-laid web

Japanese essence is versed in development went the roller bearing that uses for elevator windlass- - " elevator moves a roller bearing automatically with Jing Yin low vibration " series. Turn sound falls not only the 1/5 to the past, clearance limits also was reduced make an appointment with 1/2.

Elevator windlass because action the radial load at the axis is very big, because this meeting makes,the axis produces bending. Consequently, windlass can be used mostly move a roller bearing automatically, absorb this kind of bending. In recent years, be changed as a result of the high speed of elevator and large change ceaseless development, because this is new,the product strives to reduce vibration and rotational noise.

Specific for, new series improved the surface roughness of roller, inner ring and outer lane chamfer and circularity. Used circularity and roller diameter difference to be before 1/2, surface roughness is about before the roller of 3/4. Additional, inside and outside encircles what the circularity of orbit face also reached a level to make an appointment with 1/3, surface roughness is 2/3 about.
