Hybrid Ceramic Ball Bearings Pdf

They feature rings of bearing steel and balls of bearing grade silicon nitride.

Hybrid ceramic ball bearings pdf.

This unique ceramic material insulates the bearing against passage of stray electri cal currents while also providing extended. Hybrid bearings with ceramic balls hybrid bearings using ceramic balls are designed for applications where high grade electrical isolation is necessary and or high speeds occur. 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. 25 000 min 1 dmn 2 75 106 lubrication.

Long life and the need for minimal lubrication make this material appropriate for extreme applications. There are advantages to both hybrid and full ceramic ball bearings but it s best to speak to an expert if you re unsure whether hybrid or ceramic bearings are right for you. 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. We developed hybrid ceramic ball bearings using silicon nitride ceramic balls for turbochargers which have long life low power loss high seizure resistance and high durability and started mass production from 1998.

When most people think of ceramic bearings they are referring to hybrid bearings. Mrc hybrid deep groove ball bearings provide a highly effective solution for both new and installed electric motors and gen erators. 1 spindle angular contact ball bearing product. The robust design together with a combination of steel and ceramics makes the bearings useful for many different applications.

In addition to being excellent electric insulators hybrid bearings have a higher speed capability and will provide longer service life than all steel bearings in most applications. Ceramic hybrid bearings. Ceramic hybrid bearings have steel races and ceramic balls. Hybrid ceramic bearings 20 to 30 reduction in temperature rise upper limit of rotational speed range is 1 2 1 5 times higher compared to koyo steel bearings rotational speed.

Ceramic balls are suitable for applications where high loads high speeds and extreme temperatures are factors. This is the first adoption of hybrid ceramic ball bearings for passenger car turbochargers in the world. Hybrid bearings use ceramic balls paired with metal inner and outer rings. Oil or grease spindle power.

Hybrid ceramic bearings have traditional 52100 steel or stainless steel rings with ceramic silicon nitride si3n4 balls. Mrc hybrid ceramic ball bearings use a combination of traditional 52100 steel rings precision matched with silicon nitride ceramic balls. 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.
