NU312 bearing 60*130*31mm high capacity cylindrical roller bearings NU312EM have high bearing capacity. The new structure design of the flange and the end face of the roller not only improves the axial bearing capacity, but also improves the lubrication condition of the contact area between the roller end face and the flange, and improves the ...
NSK NU314EM Single row Cylindrical roller bearings with brass, ring guided cage. These EM series Cylindrical roller bearings have higher load carrying capacity, lower noise and superior cage strength than the ordinary type. Product data of NSK NJ314EM Cylindrical Roller Bearing. d=70 mm Inside Dia
running of traction motor bearings is an occurrence of electric pitting of the bearings. To prevent electric pitting, NSK developed ceramic coating insulated bearings and PPS-resin coating insulated bearings (Photo 1). Relationship between bearing temperature and insulation resistance of ceramic-insulated bearings was assessed.
By combining technology with our design engineering expertise we are able to offer a breadth of advanced bearings and solutions. With variety of bearings, competitive prices, fast delivery and good after-sale service, hope we will get a chance to talk bearings together. NSK cylindrical roller bearing catalogue:
