Koyo hybrid ceramic ball bearings.

The selection of a koyo ceramic bearing for the use in a highly corrosive environment should be examined very carefully. Here you will find product information and case studies relating to bearings and oil seals. Composition of ceramic bearings koyo ceramic bearings are divided into full ceramic bearings with all components namely the outer ring inner ring and rolling elements made of ceramic and hybrid ceramic bearings with. Mrc hybrid ceramic ball bearings use a combination of traditional 52100 steel rings precision matched with silicon nitride ceramic balls.

This is the website for jtekt s koyo bearing brand. Are suitable for applications which run in water alkaline environments or reactive gas. Hybrid ceramic bearings are widely used in such environments because the ceramic inner ring and balls serve as insulators. 1 wind turbine generator product.

Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways. Standard bearing steel balls ceramic bearing 15 no coolin cooling 2 000 rotation speed c oil jet lubrication 1 life time 10000 load oil air radial 100 n. Special environment ball bearings. Ceramic rolling elements are lighter harder and corrosion resistant enhancing performance and reducing maintenance down time.

Silicon nitride rolling elements can extend bearing service life by offering enhanced bearing performance even under difficult operating conditions. Hybrid ceramic bearings prevention of electrical pitting extension of grease service life three times longer than koyo steel bearings rotational speed. Material of inner and outer ring of hybrid ceramic bearing should be decided according to applications and their conditions. Hybrid ceramic bearings have traditional 52100 steel or stainless steel rings with ceramic silicon nitride si3n4 balls.

4 k series full complement hybrid ceramic ball bearing. Ceramic is the perfect material for any application seeking to achieve higher rpm s reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present. Axial 588 n iso vgio 0 004 cc min 60 ne min notes 2. Hybrid bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride si 3 n 4 which make the bearings electrically insulating.

Practical realization of the world s first ceramic bearing in 1984 reliable corrosion resistant and suitable for use in solutions. Koyo ceramic hybrid ball bearings are designed for a wide range of extreme applications where high temperatures high speeds or stray electric currents impacting bearing life especially in electric motors. In addition to being excellent electric insulators hybrid bearings have a higher speed capability 1 2 1 5 time limit of rotations compared to steel bearing and will provide longer service life lower friction and a lower level of energy consumption than all steel bearings.
